I ran into this exact issue in the past, searching for possibilities to
boot Nova instances using PXE.
Certainly the actual boot server should not be provided by Nova in any
way - it's more about getting a VM to network boot.
Actually the only change required would be to enable netboot via the
There also have been blueprints or implementation attempts for nova before:
Maybe if someone from the Nova devs would give an indication if
supporting network boot would be worth discussing?
The most basic use-case certainly are staging environments for physical
(server) systems that do network boot.
