I don't have tested it to be honest (because don't use efi in
production, and I really don't known how to verify that it's working
fine after a migration+ also the size param) , so it was more by
security

but as it's attached to -machine... directly instead -drive, I really
don't known.  and they was also the version gate for old machine
version without raw support.

We also need to handle migration+storage motion for local dirve between
pve8->pve9, and
I don't have tested if pve8 can still use drive-mirror to pve9 nbd
blockdev.


I only have tested live vm migration with shared storage between pve8
to pve9 without efi,
and the switch from drive to blockdev was working fine.
