MAAS KVM Host Fails Deployment w/error in rackd.log

[nwalling]

Hello,
MAAS Version 3.2.5

I am deploying a machine as a MAAS KVM Host that uses LXD like the picture below:

The machine deploys the OS, then does the reboot, but never finishes rebooting and the deployment eventually fails by timeout. There is an error present in rackd.log:

2022-09-19 15:49:52 provisioningserver.rpc.pods: [critical] Failed to discover VM host.

Any help is appreciated

Same issue here on 3.2.6. Libvirt works but LXD does not.

Any update on this please, I am also facing same issue as @nwalling mentioned and it is working good as a libvirt.
I am using 3.2.6-12016-g.19812b4da version from 3.2/stable channel.

I’ve opened up 2 different tickets concerning KVM host issues. It looks like one was patched for the 3.3.0 release (https://bugs.launchpad.net/maas/+bug/1984141), but the other with incorrect resources hasn’t even been assigned (https://bugs.launchpad.net/maas/+bug/1982423). Fingers crossed all of these get patched quickly. We use KVM hosts a lot and right now, it’s at a complete stop.

I am having the exact same problem with my KVM deployment right now. In my terminal I can see that it says “Reached target Cloud-init target,” but then the GUI hangs with the “Rebooting” message and doesn’t add the machine to the KVM dashboard.

I believe this is also replicated in this open bug report, but if there are any additional details anyone thinks should be included do say!
