Thank you for your help!

Most likely your backup file is corrupt.

 

[V3R4DE]

The backup completed with no errors and the files are on and external USB drive. I can not believe that they are corrupt.
Any other possibilities?

What kind of USB drive do we talk about here?

 

[V3R4DE]

Its an 1 TB HDD from WD, USB 2.0

did you create the backups with an early version of the beta? if yes, there was a bug, where the backups written were corrupt

 

[wbumiller]

Specifically compressed backups created with qemu <2.9.0-1~rc2+4 in the beta.

if you used the old version for creating the backup, the backup is faulty. create a new backup and then you can restore it.

I need to reboot after upgrade?

I need to reboot after upgrade?

If you installed a new kernel, yes. If you just upgrade qemu, a stop and start of the VM is enough.

I have the same problem in a proxmox beta Virtual Environment 5.0-5 / c155b5bc
and I urgently need to recover that vm. I've already tried in the other versions of proxomox that follow and I get the same error

beforehand
thank you
