Re: [libvirt] [PATCH] qemu: Avoid assigning unavailable migration ports

From: WangYufei <james.wangyufei(a)huawei.com&gt; https://bugzilla.redhat.com/show_bug.cgi?id=1019053 When we migrate vms concurrently, there's a chance that libvirtd on destination assigns the same port for different migrations, which will lead to migration failure during prepare phase on destination. So we use virPortAllocator here to solve the problem.
