HVM-boot-policy
The boot policy for HVM guests. Either BIOS Order or an empty string.

HVM-boot-params
The order key controls the HVM guest boot order,
Represented as a string where each character is a boot method:
D for the CD/DVD, c for the root disk, and n for network PXE boot. The default is dc.
