To summarize:
L0 (bare-metal):
- guestfish run: ~ 3 seconds
L1 (guest):
- w/o nesting, guestfish run: ~ 52 seconds
- w/ nesting, guestfish run: ~ 8 seconds (Almost 6 1/2 times speed improvement)
Or to put it another way, nested hardware virtualization is over twice
as slow as ordinary hardware virtualization :-)
However it's still a lot better than TCG, so this is good.
