Fedora VM created on Gnome Boxes lost its disk

[dalvarezt (Daniel Alvarez Torres)]

Hello!

I had been working for days on a VM with Fedora 41, created with Boxes. I updated the VM and the host (also Fedora, 40) and, without making any other change, the VM stopped booting. The boot console (see screenshot below) indicated that the primary disk was not initialized.

I booted with Fedora Live CD ISO and found that the disk appears as if it wasn’t initialized:

I also ran fdisk and it shows the disk type as “dos” (?!):

Please, do you have any advise on how to diagnose the cause and, perhaps, recover the VM?

Thanks!!

There’s a lot about this that doesn’t make much sense. Can you try running sudo partprobe /dev/vda and then see if the fdisk output makes more sense?

Thanks!.. I ran it and this was the output:

liveuser@localhost-live:~$ sudo partprobe /dev/vda
Error: Invalid argument during seek for read on /dev/vda
