The conversion restores the partitions as basic
- You back up a machine with LVM or RAID;
- When an automatic conversion to a new virtual machine is attempted, the LVM / RAID is not recreated.
This behavior is by design.
Automatic conversion restores the drives as basic, and the boot sector is set up to boot properly.
As workaround, use the manual conversion mode. There you can define the new LVM / RAID structure.
