Hi Iremonger,

You had same ask in my last version, and I was aware of that while
preparing this version. The reason I didn't include it is the same
as I replied to you last time: it's a very rough test guide; the
formal test guide would be with 2 hosts, and also you have to establish
a connection to the VM before migration and make sure it still works
right after the migration.

So, I will consider to add such formal test plan after validation is
done from validation team.

I don't think that's the right place: we can't do the live migration
test with the vhost-switch example: it includes some hardware features,
such as VLAN. Those info would be lost after migration.

And that's the reason I choose OVS.

Good suggestion; I will think what I can do for it.
