MaaS Virsh Power Type - Power error

Users
1

I have configured MaaS machine with power type “Virsh (virtual systems)” like this:

Power type: Virsh (virtual systems)
Address: qemu+ssh://ubuntu@192.168.8.11/system
Password (optional): none
Virsh VM ID: e0974a91-0120-486c-8a04-d20bfbb987fa

I’m able with user ubuntu and root to execute command from the maas host (rackd+regiond) and I get response with UUID of the VM:

virsh -c qemu+ssh://ubuntu@192.168.8.11/system domuuid vmname
e0974a91-0120-486c-8a04-d20bfbb987fa

Or I can get list of VMs without any issue (ssh key login). But there is still “Power error” in MaaS. I already installed missing package “libvirt-clients” to MaaS and I rebooted it. Other power type for example IPMI is working for me. I could not see anything relevant in the logs. What I can do more to find out the issue? MaaS 3.3.5 on Ubuntu 22.04.4, all updates installed + snap refreshed.

Thanks

Hi @borsik ,

this is a known issue caused by an unforeseen update of one of MAAS dependencies. We have a fix and we are currently working towards publishing new stable releases as soon as possible.

Meanwhile, you can refresh your snap to a hotfix branch:

sudo snap refresh --channel=3.3/stable/hotfix-bug-2053033 maas

I am using MAAS 3.5.3-16341-g.7adb035d6-0ubuntu1~22.04.1 (installed w/apt) on an up-to-date Ubuntu 22.04 LTS, and seemingly running into the problem reported here.

I am successfully able to get my libvirt VM to PXE boot with MAAS, but when setting up Power Type to virsh prior to Commissioning, I run into the problem described here.

My connection URL is

qemu+ssh://root@10.61.60.2/system

which is what I use with my local virt-manager (desktop Linux) to connect to 10.61.60.2 (remote server/KVM host).

and the Virsh VM is the UUID I pulled from the VM element <uuid>......</uuid>

MAAS logging ends up in the journalctl facility on my host, and in paging through the results for the following two invocations, I see no errors:

The following is what I have pulled out of journalctl on 10.61.60.2:
