[libvirt] [PATCH] migration: remove direct migration dependency on version1 of driver
From: Nikolay Shirokovskiy <Nikolay Shirokovskiy nshirokovskiy(a)virtuozzo.com>
Direct migration should work if *perform3 is present but *perform
is not. This is situation when driver migration is implemented
after new version of driver function is introduced. We should not
be forced to support old version too as its parameter space is
subspace of newer one.
