Debian appvm with zfs fails to start

Update: An appvm based on the debian-12-minimal template works fine: I’m able to start, restart, and access my zfs filesystem.

My goal is to have an appvm with zfs and ssh-server. I am using 4.2 rc3 with updates

A template based on debian-12-xfce with zfs installed starts and restarts without complaint.

I created a new appvm based on this template using the ‘Create New Qube’ system tool. I verified in the settings that the kernel is set to pvgrub2-pvh. The appvm fails to start with the error message ‘Cannot connect to qrexec agent for 60 seconds: …’

What appears to be the relevant part of the log seems to be that there is an error with libglib-2.0:

Any suggestions would be appreciated.

Try to increase the initial memory for this appvm.

I increased from 400 M to 2000 M and get the same message.

Thanks for the suggestion.

Additional troubleshooting background:

From a fresh debian-12-xfce template:

An appvm created from template after installing distribution kernel in template starts and restarts without complaint

An appvm created from template after also installing dkms also starts and restarts.

An appvm created from template after also installing zfs doesn’t start


Starting with the debian-12-minimal update I am able to install the distribution kernel, dkms, and zfs.

An appvm created from the resulting minimal template starts and zfs works.
