[Bug 1845628] [NEW] Check UEFI support not insufficient

 

Public bug reported:

Now, delete instance, swap volume and snapshot, we always clear NVRAM flags.
This is not right, currently we only check the host support uefi booting for guests from "_has_uefi_support".
If an instance not boot with UEFI but the host enable UEFI, we also needs to clear NVRAM flags in guest delete_configuration.

IMO, we need to check the instance(guest) and host support UEFI both,
like check the instance's image_meta.
