Proxmox VMA can not be deployed

[skutter-de]

I built an image using this command:

nix --extra-experimental-features nix-command --extra-experimental-features flakes run github:nix-community/nixos-generators -- --format proxmox

after scp'ing the image over and running qmrestore, I get the following error:

root@pve1:/var/lib/vz/dump# qmrestore nixos-24-11.vma.zst 111111
error before or during data restore, some or all disks were not completely restored. VM 111111 state is NOT cleaned up.
ERROR: couldn't determine archive info from '/var/lib/vz/dump/nixos-24-11.vma.zst'

I haven't found a way to get a more verbose error, this is all I have.

Likely needs to be fixed in nixpkgs. nixos-generators is just a thin layer above it:

nixos-generators/formats/proxmox.nix

Line 7 in 0552f78

"${toString modulesPath}/virtualisation/proxmox-image.nix"

Same problem here and very annoying. Did someone manage to get that problem fixed?

@Gaming4LifeDE Did you manage to fix it meanwhile?

@Gaming4LifeDE Just found the solution in some older issue: the file name needs to start with vzdump-qemu-!
So filenaming convention is vzdump-qemu-whatever.vma.zst. Otherwise the import fails.

Damn I just lost half a day of my life on this frikin issue. 😃
