Snapshot of what?

I looked into this again and libvirt can only take snapshots of a VM with secure boot enabled if it is powered off. So, I could make it automatically power off the VM, take the snapshot, and power it back on. This is a pretty big change and I'm still thinking about whether I want to add it. It definitely won't be added to the OMV 6.x version of the plugin. If you want snapshots, please power off the VM and it will work.

Nope this does not work

I wouldn't have mentioned if I didn't test it. I'm a little mystified why it isn't working on your system. What is the complete error? cut&paste from the bell in the top right of the web interface.

Probably something windows related. Can you post the <os> element from the VM's XML? It should look something like this:

Code

<os firmware='efi'>
<type arch='x86_64' machine='pc-q35-8.1'>hvm</type>
<loader secure='yes'/>
<boot dev='hd'/>
<boot dev='cdrom'/>
</os>

Not sure how I am going to test Windows VMs though...

here it is

<os>

<type arch='x86_64' machine='pc-q35-7.2'>hvm</type>

<loader readonly='yes' secure='yes' type='pflash'>/usr/share/OVMF/OVMF_CODE_4M.ms.fd</loader>

<nvram>/var/lib/libvirt/qemu/nvram/win11_VARS.fd</nvram>

<boot dev='hd'/>

<boot dev='cdrom'/>

</os>
