EXT4-fs error (device mmcblk0p2)

[Pascal]

hi,

I play to emulate the Raspberry Pi and, to avoid having to wait for the (re)start of my slow VM, I recorded a snapshot at the end of the first boot.

but when I reload this snapshot, I have a lot of error messages (EXT4-fs error (device mmcblk0p2) ... reading directory lblock 0) and I cannot use my virtual machine anymore.

are snapshots functional with this type of VM or is the problem elsewhere ?

regards, lacsaP.
