AppVM won't start any application

[bfgvusmcar]

Hi, I am a new user and I'm very happy with the OS. I installed it a few days ago and I seem to have an issue. I would delete and re-create the qube but it could be a helpful opportunity for both me and you to debug some issue.

I have a qube based on debian-10 fully updated. It didn't have any particular configuration, a bigger volume as I planned on using it more. Suddenly it won't start any program, not even the terminal.

From /var/log/xen/console, it seems like the AppVM is starting:

Debian GNU/Linux 10 vm hvc0

vm login:

A popup now appears (it wasn't appearing before): "Domain has failed to start: Snapshot origin LV vm-debian-10-root not found in Volume group qubes_dom0".

Another popup: "Device /tmp/sanity... removed (deleted)", I don't know if it's related.

When I shut down the AppVM, it "restart by itself". When I shut it down again then it doesn't boot anymore.

Where can I find more logs on this, how should I debug it?

This does look like an issue. xvdb device is "private" volume, where /rw
+ /home lives, so this is important part.
Try extracting more info about it from dom0:

qvm-run -p -u root vm 'systemctl status system...@dev-xvdb.service'

Check also earlier entires, specifically "Initialize and mount /rw and
/home" service (some its messages are marked mount-dirs.sh).

This on the other hand is about "root" volume. But LVM setup happens
before starting anything inside the VM, if this would be the cause, you
wouldn't get any output from the vm. Check modification time on the log,
if it's really about latest try.

Can you start the debian-10 template itself? Or it fails the same way?
