Introduction
The Incus team is pleased to announce the release of Incus 6.5!
A strong focus for this release was on performance. Costly internal calls like resolving large number of profiles and devices have been optimized significantly leading to up to a 20-30x performance improvement. Similarly, handling of systems with thousands of instances per server has also been greatly improved, cutting down startup checks from tens of minutes down to tens of seconds.
But this isn’t just a bugfix release, Incus 6.5 also introduces quite a few new features and other improvements. From making our CLI experience more consistent, to making it easier to perform low-level actions on virtual machines, to improving the life of application container users and through a number of great new features for OVN users, this release should have something for everyone!
As usual, you can try it for yourself online: Linux Containers - Incus - Try it online
Enjoy!
New features
Instance auto-restart
A common request ever since we first rolled out application containers support in Incus, the ability to have instances automatically restart when they exit makes it easier to handle applications crashing or reloading.
This is controlled through a new boot.autorestart configuration key which when set to true will have Incus attempt to restart a given instance up to 10 times over a 1 minute time span.
User requested instance shutdown/stop do not trigger the auto-restart logic.

Column selection in all list commands
Over the past few releases, we’ve been working on improving the consistency of the incus CLI commands. This started with making sure that all our list commands support --format and now with this release, all list commands also now support --columns.
This allows for easily customizing the output you’re getting, as well as making it much easier to script the incus command by combining both --format=csv with --column= to select just the relevant column(s).

QMP command hooks and scriptlet
Incus currently relies on QEMU to run its virtual machines.
The way Incus interacts with QEMU can be a bit complex at times as it’s effectively done through three different mechanisms:
- QEMU command line
- QEMU configuration file
- QEMU Machine Protocol (QMP)
We usually try to avoid polluting the command line as much as possible, so this is kept to a minimum, but we allow the user to pass in additional arguments through raw.qemu.
Our preference for any device which doesn’t need live-updating or doesn’t need to ever be hotplugged or hot removed is the use of the QEMU configuration file. This is easily templated and can pretty easily be tested. We have the raw.qemu.conf configuration option that can be used to extend or override the content of that configuration file.
And then we have QMP which we use for anything hotpluggable, so effectively all disks, network interfaces, USB devices or any other PCI devices. As the QEMU team is slowly trying to deprecate the configuration file, we expect to progressively be moving more and more of the VM configuration over to QMP.
The main issue with QMP so far has been that unlike the QEMU command line or a config file, it’s very opaque. It’s not possible to easily see what’s been configured and because any of those objects will have been configured after QEMU started, it wasn’t possible to override or re-configure them through the existing mechanisms.
But things are different now thanks to a few new configuration options:
raw.qemu.qmp.earlyraw.qemu.qmp.pre-startraw.qemu.qmp.post-startraw.qemu.scriptlet
The first three take a JSON list of QMP commands. QMP commands are normally already all JSON encoded, so that makes it easy to add a number of custom commands to the instance configuration. The commands will be run in order at one of the specified times.
early runs prior to Incus having added anything through QMP, pre-start runs after Incus has added all its devices through QMP and post-start runs immediately after QEMU was instructed to start the VM.
raw.qemu.scriptlet is an even more flexible option as it takes a sriptlet (python-like syntax) which must define a function named qemu_hook and passes it the stage as an argument. That stage is one of early, pre-start or post-start. The different between that and the raw.qemu.qmp options is that a scriptlet can handle command responses and have logic to react to it.
That means that this QEMU scriptlet can call the run_qmp command, pass a custom QMP command, read through its return value and issue more commands if needed, allowing for dynamic re-configuration of the VM.
Note that this is a very low level mechanism which we only expect expert users to use in very specific cases. As with any raw configuration key, its use is effectively unsupported by the Incus team and it should also be kept disabled for any untrusted projects.
Live disk resize support in virtual machines
It’s now possible to resize either the VM root disk or any attached disk and have the VM be notified of the change. This then causes the operating system to update the size of the disk and allows the user to immediately make use of the additional space without having to restart the VM.
stgraber@castiana:~$ incus exec v1 bash
root@v1:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 10G 0 disk
├─sda1 8:1 0 100M 0 part /boot/efi
└─sda2 8:2 0 9.9G 0 part /
root@v1:~#
exit
stgraber@castiana:~$ incus config device override v1 root size=20GiB

stgraber@castiana:~$ incus exec v1 bash
root@v1:~# lsblk

root@v1:~#
PCI devices hotplug
Adding and removing PCI devices on a VM can now be done live.
This now matches the behavior found in NIC, GPU and disk devices.
OVN load-balancer health checks
Incus’ support for OVN load-balancers has so far been pretty basic, essentially being limited to just basic load-balancing of traffic on a set of target with no monitoring of the backend.
But this is now changing with initial support for OVN’s load-balancer health checks.
This is configured through a set of configuration keys on the load-balancer:
healthcheck=> Enables health checkinghealthcheck.failure_count=> Number of failed attempts to consider backend as failedhealthcheck.interval=> How often to check the backends (in seconds)healthcheck.success_count=> Number of successful attempts to consider backend as onlinehealthcheck.timeout=> How long to wait for a response before considering it failed
Only healthcheck is required, all the others have reasonable defaults.

ECMP support for OVN interconnect
The network integration support for OVN interconnect has been extended in a few small ways:
- The
ovn.transit.patternconfiguration option now supports a newpeerNamevariable - It’s now possible to have multiple peers on a network targeting the same network integration
- IP allocation on the transit switch is now recorded directly in the OVN database rather than relying on random subnets
The end result is that it’s now possible to change the default core.transit.pattern to include peerName in the template and then add multiple peers to a network, all pointing to the same interconnection.
This internally will result in mutliple transit switches being created and so long as the peer names match on all participating systems, traffic will be balanced between those switches through ECMP.
Doing so allows for very effective load-balancing of interconnection traffic.

Promiscuous mode for OVN NICs
A new security.promiscuous configuration key is now available on OVN NICs.
When it’s enabled, any OVN traffic that has an unknown MAC address as its destination will now be sent over to the OVN NIC.
The main use for this is for nested environments where you want to have some nested containers or VMs directly sit on the parent OVN network without having their own dedicated ports.
This is typically a development/testing use case as promiscuous mode causes a lot of unnecessary network traffic to hit the NIC.

Ability to run off IP allocation on OVN NICs
Another new OVN NIC option is the ability to turn off IP allocation completely.
This is often related to the previous case where a promiscuous NIC typically doesn’t need to have its own IPv4 and IPv6 address. To handle this, it’s now possible to set both ipv4.address and ipv6.address to none, disabling allocations.
Note that OVN doesn’t allow disabling just one protocol, so both keys must currently be set to none for this to work.

Customizable OIDC scope request
It’s now possible to configure the list of OpenID Connect Scopes that are being requested.
Setting oidc.scopes in the server config will override the default of openid, offline_access and can be useful to pull in additional information through scopes like profile.

Configurable LVM PV metadata size
Very very large LVM volumes groups containing thousands of logical volumes may exceed the reserved metadata size.
This was already configurable on LVM thin provisioned pools (default), but for thick provisioning, there was no matching configuration.
Now the lvm.metadata_size configuration key can be set to override LVM’s default.
Note that this can only be done at creation time.

Configurable OVS socket path
There are a few cases where OpenVSwitch doesn’t run at the usual address.
The most common case of this would be MicroOVN users where the OpenVSwitch socket is instead stored within /var/snap/microovn/common/....
Until now, those users had to jump through some hoops to get a working OVS socket in /run so Incus would properly connect to it.
With this change, it’s now possible to set the network.ovs.connection configuration key to a valid OVSDB connection string and have Incus reach OpenVSwitch through that. The default value is unix:/run/openvswitch/db.sock.
