Pushed, thanks!

I guess that generally you cannot because it requires hardware
virtualization support (i.e. POPCNT CPU feature and maybe something
else). Probably it's possible with KVM's nested virtualization, I've
been wanting to check that for a while but somehow always forget about
that when I have time.

True.

I didn't actually test this[1], but both the code and the
tests look reasonable enough, plus 'make check' and 'make
syntax-check' are all green[2] on FreeBSD, so:

ACK


[1] Can you run bhyve guests inside a FreeBSD KVM guest?
[2] Well, mostly. We really should fix qemuxml2argvtest once
and for all, and it looks like we're sooo close now!

[libvirt] [PATCH] bhyve: fix virtio disk addresses

2017-02-01 Thread Roman Bogorodskiy 
Like it usually happens, I fixed one thing and broke another:
in 803966c76 address allocation was fixed for SATA disks, but
broke that for virtio disks, because it dropped disk address
assignment completely. It's not needed for SATA disks anymore,
but still needed for the virtio ones.

Bring that back and add a couple of tests to make sure it won't
happen again.
