Re: [libvirt] [PATCH] migration: remove direct migration dependency on version1 of driver

From: Nikolay Shirokovskiy <Nikolay Shirokovskiy nshirokovskiy(a)virtuozzo.com&gt; 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.
