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)
To clarify, by "w/ nesting" what I meant is, L1's qemu-kvm cli will have:
-cpu Core2Duo,+vmx # or whatever the model is
And, w/o nesting": No -cpu parameter in L1's qemu-kvm cli.
