The Oxide CLI and Rust SDK have been updated to support all the new features such as boot disk designation, instance update, and VPC internet gateway. Please be sure to upgrade to the latest versions.
The Go SDK and Oxide Terraform Provider have also been updated to support boot disk designation. They will be enhanced to manage internet gateway objects in a future release.
In this release, the control plane is enhanced to attempt restarting instances that have gone into the failed state. This new feature allows previously running instances to come back up after software updates. See New Features for more information.

Installation

Oxide Computer Model 0 must be installed and configured under the guidance of Oxide technicians. The requirement may change in future releases.

Upgrade from version 10 is supported. We recommend shutting down all running instances on the rack before software update commences. Any instances that aren’t stopped for software update are transitioned to the failed state when the control plane comes up. They will be automatically restarted afterwards in a controlled manner. Failed instances may also be started or stopped manually while they are waiting to be restarted.

All existing setup and data (e.g., projects, users, instances) remain intact after the software update.

New Features

Improved Failed Instance Handling

The Oxide control plane has been enhanced to allow failed instances to be auto-restarted or started/stopped manually. Prior to this release, instances marked failed because of planned or unexpected sled reboots or hypervisor process failures can only be revived by deleting/recreating them. The handling of instance state transition has also been improved to prevent timeout-related failures (e.g., omicron#5235).

Auto-restart policy is configurable on a per-instance basis using the new PUT /v1/instances/{instance} endpoint (or the corresponding instance update CLI command). If no policy is set, instances will automatically restart by default.

Boot Disk

Users can now designate one of an instance’s disks as its boot disk. The boot disk can be specified at instance create time or changed later using the new PUT /v1/instances/{instance} endpoint (or the corresponding instance update CLI command). In a future release, this endpoint will also be used to change instance CPU and memory size. Instance updates are allowed only when the instance is stopped.

Prior to this release, when an instance was provisioned, the first disk in the request body was implicitly treated as the boot disk. The firmware also attempted to boot from other disks in an unpredictable fashion if it could not find the bootloader on the first disk, sometimes resulting in unusable instances as described in this terraform provider issue.

Telemetry

Prior to v10, the rack telemetry data was limited to rack-level network metrics, resource utilization, and a subset of disk and instance data. In v10 and v11, we have further expanded the metrics coverage to include:

Power, component temperatures, fan speeds
Instance network interface (e.g., I/O, packet drops, errors)
Virtual disk statistics improvements

The metrics data can be consumed using Oxide’s Oximeter Query Language, "OxQL", which is described in RFD 463. Please note that the query language is experimental and its syntax may change in future releases. Details about available timeseries will be added to this site soon.

Internet Gateways

Internet gateways support the routing of VPC traffic to networks outside of the Oxide rack. They can be used to ensure that instances only use certain external IP addresses when sending traffic to a given network. Prior to this release, only the system-defined internet gateway was available for routing external traffic using the default IP pool of each silo. Starting from v11, project users can optionally set up internet gateways in their VPCs against other IP pools. These gateways can be applied as routing targets to customize instance outbound traffic based on the packet destinations. You can find an example of such granular routing setup and more details about internet gateways in the Networking guide.

Please note that the management of internet gateways is available through API only at this time. The web console, Go SDK, and Terraform provider will provide the same support in the next release.

Rack Reconfigurator

The reconfigurator module provides the foundation for Oxide control plane service configuration changes during hardware and software maintenance. It is accessible by Oxide technicians only at this time. It will be made available to rack operators in the form of component update/replacement capabilities in a future release.

Enable replacement of external DNS instances
Support horizontal scaling and replacement of oximeter (metrics collector) instances

Web console changes

Image uploads are ~3x faster, as fast as CLI (omicron#6690)

v7

system

Important Notes

The instance_create API endpoint now returns a success response as soon as orchestration is finished. The hypervisor-level setup and booting has been made asynchronous to avoid timeouts (e.g., when there are many concurrent large instance requests). Care must be taken when provisioning instances to poll for instance state and connect to an instance only when it has transitioned to the running state.
The Oxide CLI, Go SDK, and Terraform Provider have been updated for various API enhancements such as IP pool utilization described under New Features. Please ensure you obtain the latest version of the clients.

System Requirements

Please refer to v1.0.0 release notes.

Installation

Oxide Computer Model 0 must be installed and configured under the guidance of Oxide technicians. The requirement may change in future releases.

Upgrade Compatibility

Upgrade from version 6 is supported. We recommend shutting down all running instances on the rack before the software update commences.

All existing setup and data (e.g., projects, users, instances) will remain intact after the software update.

New Features

Floating IPs in web console

The web console now supports creating and deleting floating IP addresses, as well as attaching to and detaching from instances.

IP pool utilization in API and web console

The IP pool management page in the web console now includes real-time utilization data, giving fleet administrators visibility into the number of external IP addresses currently allocated in each pool. See also the ip_pool_utilization_view API endpoint.

Bug fixes and minor enhancements

New API endpoint floating_ip_update for updating floating IP name and description (omicron#5016)
New API endpoint networking_bgp_message_history for retrieving BGP message history (maghemite-PR#179)
Fix capacity and utilization showing "undefined" in some cases (console#1954)

v6

system

Important Notes

IP pools have been reworked for greater flexibility and can now be managed through the web console UI.
1. In v5, an IP pool was either fleet-scoped (i.e., available to users in all silos) or silo-scoped (i.e., available in one silo). In v6, an IP pool can be linked to any number of silos. This enables configurations that were not possible in v5, such as an IP pool shared by silos A and B but not C.
2. There is no longer a concept of fleet-scoped pool: users can only allocate IP addresses from pools explicitly linked to their silo. The behavior of a fleet-scoped pool can be recreated in the new model by linking a pool to every silo individually.
3. The software update process will set up links between existing pools and silos in a way that preserves v5 behavior:
  1. Formerly fleet-scoped pools will be linked to every silo.
  2. If a formerly fleet-scoped pool was marked “default” for the fleet, it will continue to be the default for each silo unless that silo had its own default pool overriding the fleet-level default.
4. After setting up a new silo, you will need to link an IP pool to it before users can allocate external IPs.
5. Please review the updated IP Pool Management guide and API docs and update any API client that manipulates IP pools.
The Oxide CLI, Go SDK, and Terraform Provider have been updated for floating IP attach/detach support and the IP Pool changes mentioned above as well as other API enhancements, please ensure you obtain the latest versions.
The NewClient function in the Go SDK has been modified to no longer require user agent, and now takes a Config struct instead. You can find more information about this, and other changes in the Go SDK changelog.
The latest release of the Oxide CLI produces JSON-formatted output.

System Requirements

Please refer to v1.0.0 release notes.

Installation

Oxide Computer Model 0 must be installed and configured under the guidance of Oxide technicians. The requirement may change in future releases.

Upgrade Compatibility

Upgrade from version 5 is supported. We recommend shutting down all running instances on the rack before the software update commences.

All existing setup and data (e.g., projects, users, instances) should remain intact after the software update.

New Features

This release comes with two new features for rack switch failover support, security fixes, and other minor enhancements.

Fault-Tolerant Multipath Connectivity

Each of the two Oxide rack switches (aka “sidecars”) can now be connected to two or more uplinks allowing rack connectivity to remain available should there be a single physical switch or uplink failure. For static multipath routing configurations, this is made possible through Bidirectional Forwarding Detection (BFD) provided in this release. New tunnel routing capabilities within the rack’s internal network ensure packets leaving the rack are always routed to a rack switch with sufficient connectivity to forward packets to their final destination. For BGP routing configurations, tunnel routes adapt to changes in BGP routing tables. These features work together to eliminate single points of failure by automatically detecting connectivity issues and redirecting network traffic to the functional network paths. (Note: BFD verifies IP connectivity between the source and destination by actively sending control packets and/or passively responding to control packets from the neighboring devices.)

Floating IP address attach/detach

The floating IP feature introduced in v5 allows a consistent IP addresses to be allocated to a new instance and the address to be de-allocated upon instance termination. The feature has been further enhanced in v6 to allow floating IPs to be allocated to, or de-allocated from, running instances. In other words, you can move a floating IP from one instance to another on the fly. See the latest Guest Networking Guide for more information.

Web console improvements

Manage IP pools: add/remove IP ranges, link/unlink silos, set default pool (console#1910)
Select from list of SSH keys on instance create form (console#1867)
Firewall rules table includes priority and direction, is sorted by priority (console#1887)
Add user data (e.g., cloud-init config YAML) field under Advanced on instance create form (console#800)
Show external IPs at top of instance page (console#1882)

Bug fixes and minor enhancements

TCP state machine race condition could leave Nexus API or guest instance TCP connections in the wrong state (opte#442)
Outbound TCP flow occasionally hung as old TCP flows were in FLOW_WAIT, blocking port reuse (opte#436)
Instances could not transition to failed state when their propolis zones crashed or were purged (omicron#4709)
API
- Select the SSH keys to inject into instances at create time (omicron#3056)
- Users can list IP pools available to them (omicron#2148)
- Project deletion did not enforce the removal of the project’s floating IP addresses (omicron#4854)
- Instance create requests with hostnames not conforming to RFC 1035 are now prohibited (omicron#4938)
Web console
- Enhance number field and use it more consistently (console#1926)
- Fix y-axis units for large numbers on instance disk metrics charts (console#1916)
- Clickable styling (underline and hover) on links in tables (console#1899)
- Handle empty IP address in network interface create form (console#1854)
- Instance networking config moved under Advanced/Networking on instance create (console#800)
- Don’t allow editing on the instance create form while submit is in progress (console#1893)
- Relative times (e.g., “7d ago”) have a tooltip showing absolute time (console#1879)
- Increase page size on tables from 10 to 25 (console#1878)
- Pressing enter while adding target, host, or port to firewall rule should not submit form (console#1919)
Reliability improvements
- Improved network device driver error handling (propolis#583)
- Stop checking the disk parent image/snapshot if the scrub is done (crucible#1093)
Storage performance improvements (crucible-PR#1058, crucible-PR#1066, crucible-PR#1089, crucible-PR#1094, crucible-PR#1107)
Control plane datastores now use ZFS datasets in encrypted mode (omicron-PR#4853)

v5

system

Important Notes

This release comes with new features for multi-tenant management. As part of this change, silo creation now requires a set of resource quotas (vcpu, memory, storage) to be specified.
1. As part of the software update, all existing silos will have resource quotas configured to use all available fleet capacity initially. Fleet administrators can modify the quotas afterwards via the new /v1/system/silos/{silo}/quotas API.
2. See the New Features section for more information about silo resource allocation.
A previous issue with disk deletion (omicron#3866) resulted in incomplete removal of backend data volumes and over-reported disk usage. The issue may manifest as 500 errors when a user attempts to delete a project that has no resource in it. Such partially removed disks will be un-deleted during the software update process. They are marked in faulted state so that they can be cleanly deleted again. Please review and remove any faulted disks once the system has been updated.
The disk_import_blocks_from_url API endpoint for importing disk images from a remote URL is no longer supported. Please download image files to your local workstation and use the disk_bulk_write APIs to import them instead. (Note: The oxide disk import CLI command is not affected by this change.)
The Oxide CLI binaries (v0.2.0) have been updated for the new floating IP and resource quota endpoints.

System Requirements

Please refer to v1.0.0 release notes.

Installation

Oxide Computer Model 0 must be installed and configured under the guidance of Oxide technicians. The requirement may change in future releases.

Upgrade Compatibility

Upgrades from version 3 and 4 are both supported. We recommend shutting down all running instances on the rack before the software update commences.

All existing setup and data (e.g., projects, users, instances) should remain intact after the software update.

New Features

This release includes several new features for rack management and VM instance networking:

Silo resource allocation

Fleet administrators can now set limits on virtual resources (vcpu, memory, storage) usable by individual silos. Quotas are set during silo creation and can be modified afterwards to levels at or above the current utilization. Silo administrators can query the capacity and current utilization via API or CLI to independently manage the rack resources allocated to them.

Quotas are enforced when a new disk is provisioned and when an instance is started. If the action causes the silo’s aggregate resource usage to exceed its quotas, users will receive an InsufficientCapacity error. Please refer to the new Silo Management guide for details on usable capacity and utilization calculations as well as some possible exception scenarios.

Marking sled non-provisionable

This new API allows operators to temporarily exclude a sled from new workload placement. The action may be required when diagnosing and mitigating the impact of unexpected sled issues (e.g., unresponsive sleds, unscheduled reboots). This operator API is a precursor for the sled maintenance and replacement feature set.

Floating IP address

Floating IPs are permanent, project-scoped resources which bind an individual IP address from a given IP Pool. They allow for well-known addresses to be allocated (explicitly or automatically) and assigned to target instances, making it easier to host services from a consistent address. Floating IPs are allocated or de-allocated only when instances are created or destroyed at this time. They can also be used along with ephemeral IP so that an instance can be accessed on more than one external IP address. Please refer to the user guides (Configuring Guest Networking and Managing Floating IPs) for more information.

Bug fixes:

Security fix: CVE-2023-50913 SSRF in Oxide software that could allow attacker to access the ClickHouse metrics datastore.
Spurious errors were returned for snapshot or disk deletions after multiple delete requests on the same snapshot (omicron#3866, omicron-PR#4547)
Disk create or instance start requests under high concurrency failed to complete (omicron#3304)
Instances sometimes fail to boot up when they are created under very high concurrency (propolis#535)
IP address could not be left blank when adding NIC to instance (console#1438)
Image sizes were not available on image picker (console#1824)
Project picker showed only the first 20 projects (console#1817)
Disk snapshot action did not provide any UI feedback (console#1815)
BGP configuration was not applied to switches after upgrade (omicron#4474)
BGP failed to handle ConnectRetryTimerExpires in Active state (maghemite#93)
Link parameters from rack setup was not persisted in the control plane datastore (omicron#4470)
Link config API did not allow for setting link autonegotiation (omicron#4458)
RoT on production Rev E gimlet incorrectly prohibited software update (omicron#4420)
Reliability improvements:
- Support for non-power-of-2 multipath route selection (dendrite-PR#685)
- Background tasks to populate NAT entries of sleds and instances during normal and unexpected restarts (omicron#3631)
- Better handling of racing VM suspend conditions (propolis#559, propolis#561)
- Better handling of project resource usage mismatch conditions (omicron#4426)
Storage backend reliability and performance improvements (crucible-PR#1014, crucible#1038, crucible#1021, crucible-PR#991, crucible-PR#1019, crucible-PR#1047)

system

Important Notes

Starting from this release, the numbering convention follows an integer version numbering scheme. Upgrade from v1.0.2 to this release, version 3, does not require a system reset or other special handling.
Please note that there are two functional changes around the instance lifecycle:
- The vCPU and memory resources of stopped instances no longer count toward current utilization in the web UI and system metrics API.
- The transient instance state rebooting may not be reflected in the UI or API if the reboot operation completes almost instantly. The instance may be considered running throughout the process.
  These changes allow more accurate reporting of resource utilization and reduced concurrent instance provisioning errors.
There is a change in the ClickHouse timeseries key generation method. Historical metrics are dropped as part of the software update. Utilization metrics will be re-populated once a new instance/disk lifecycle event (e.g., create, start, delete) has taken place.

System Requirements

Please refer to v1.0.0 release notes.

Installation

Oxide Computer Model 0 must be installed and configured under the guidance of Oxide technicians. The requirement may change in future releases.

Upgrade Compatibility

Upgrade from version 1.0.2 is supported. We recommend shutting down all running instances on the rack before the software update commences.

All existing setup and data (e.g., projects, users, instances) should remain intact after the software update.

New Features

This release includes a number of performance and VM workflow reliability improvements.

Support for Border Gateway Protocol (BGP); see the updated API documentation for more details about the setup
Improved virtual disk read/write performance (crucible#872, crucible#981, crucible#586)
Ping API endpoint for control plane connectivity healthcheck (omicron#3923)
Silo utilization summary table (console#1783)

Bug fixes:

Instances provisioned in bulk from the same image were stuck in stopping state due to back pressure on read-only parent (crucible#9696, crucible-PR#984)
Spurious errors returned for snapshot or disk deletions after multiple delete requests on the same snapshot (omicron#3866, omicron-PR#920)
500 errors were returned when attempting to delete images (omicron#3033)
Firewall rules using VPC as target traffic filtering was based on an instance’s private IP only but not its public IP (opte#380)
Instance DNS was hardcoded to 8.8.8.8 (opte#390)
Disk replica placement did not maximize physical disk spread over separate sleds (omicron#3702)
Guest OS panicked upon executing lshw -C disk (propolis#520)
Disk run-time metrics were not captured after a timeseries format change (crucible#942)
User with silo collaborator role was unable to start an instance (omicron#4272)
Unsuccessful deletion of running instances could still remove public IP (omicron#2842)
IP Pool API get responses now include the is_default value (omicron#4005)
Silo TLS certificate can now be specified in Silo Create UI (console#1736)
Additional stratum checks for more reliable NTP synchronization (omicron-PR#4119)
Improved physical disk out-of-space handling (crucible#861)
Improved back pressure handling under heavy disk write workload (crucible#902)
Added TLS certificate CN/SAN validation against rack external domain name (omicron#4045)
curl upgrade (from 8.3.0 to 8.4.0) for CVEs (helios#119)

Important Notes

This is the first release of Oxide Computer Model 0, also known as the “0x1” rack. In future release notes, we will include detailed changelogs for each software component to highlight changes such as new features, bug fixes, and upgrade impact.

System Requirements

Oxide Computer is an appliance built with tightly integrated hardware and software components. It requires the following supporting services external to the rack for it to be operational:

L2 network that supports bidirectional port forwarding
NTP service for system time synchronization
Domain name service and a delegated subdomain for use by the rack
Identity provider that supports SAML authentication

Supported systems for the official clients:

Browsers for web console: Chrome, Edge, Firefox, Safari
OSes for CLI: Linux, macOS, Windows

Installation

Oxide Computer Model 0 must be installed and configured under the guidance of Oxide technicians. The requirement may change in future releases.

Features

The Oxide rack covers the complete hardware and software stack for deploying and managing virtual machine instances and related virtualized resources such as

persistent block storage in the form of detachable virtual disks
snapshots and disk images
private network interface for intra-subnet access
public network interface for inbound access
built-in NAT service for outbound public network access
virtual private cloud (VPC) and firewall capabilities

Many of the popular Linux distros such as Ubuntu, Debian and CentOS are supported as the guest operating systems for VM instances. Microsoft Windows server and desktop operating systems will be fully supported soon in the upcoming releases.

The key features for operators and administrators include:

organizing and isolating virtual resources by tenants and by projects
integrating with SAML-based identity provider for identity and access management
managing IP address allocation
basic metrics and visualizations for capacity utilization

The key management features for end-users include:

self-service orchestration via the web console and API
command-line tools including Oxide CLI and Terraform
capabilities to build custom integration tools using Oxide SDK
project-level resource utilization and disk I/O metrics

The rack also comes with built-in security features to ensure all hardware and software are genuine Oxide products:

purpose-built hardware root of trust (RoT) – present on every Oxide server and switch – cryptographically validates that its own firmware is genuine and unmodified
encryption of data at rest via internal key management system built on the RoT
trust quorum establishment at boot time to ensure the cryptographically-derived rack secret is verified before unlocking storage

More details about Oxide Computer can be found in the product documentation.
