Hello,

I've just upgraded from 7.1.0 to 7.1.2 and lost my virtual machines, so I've attached "unraid-diagnostics-20250530-1028.zip" and did notice:

May 30 10:25:36 unraid emhttpd: shcmd (3510): /usr/local/sbin/mount_image '/mnt/user/system/libvirt/libvirt.img' /etc/libvirt 1
May 30 10:25:36 unraid root: Creating new image file: '/mnt/user/system/libvirt/libvirt.img' size: 1G

Was this file some how corrupted? Or what else could've caused this to happen?

unraid-diagnostics-20250530-1028.zip

I do still have the ".img" and ".qcow2" files, and am able to successfully start Home Assistant ( .qcow2 ), but starting of the ".img" files ( all Debian based VMs ), I'm unable to boot, getting the "UEFI Interactive Shell" in VNC, any ideas to restore those?

Some how the libvirt.img got corrupted or lost ( during/in the upgrade? ) and I was able to restore my libvirt.img from my backup, so I've got it working again.

Solved by restoring libvirt.img from backup.

The upgrade does not touch your files so something else caused your problem. Glad you got it working though.
