It's doable, with some caveats:
- consistency-wise, file: is not recommended. You should use tap:aio:
- mapping as sda1 instead of sda means you need to use templates (like
from jailtime.org). You won't be abe to use installer (like with
virt-manager).
- I/O performance will be slower compared to block-based vbd using phy:/
