[pve-devel] [PATCH qemu-server] clone disk: force raw format for TPM state

[Fabian Ebner]

The format can't be qcow2 for TPM state, because swtpm reads the file
directly expecting raw data.

The DiskStorageSelector in the UI hides the format for TPM state, but
still sends along format=qcow2 triggering this bug. Still, the fix
should be in the backend.
