Date: Sat, 5 Sep 2015 20:25:31 +0300 [thread overview]
Message-ID: <55EB258B.8070301@virtuozzo.com> (raw)
In-Reply-To: <1441471439-6157-1-git-send-email-vsementsov@virtuozzo.com>
Add feature:
Migration of BdrvDirtyBitmap.file field.
Bitmap 'percistancy' can be migrated only if its(bitmap) storage disk
has id and the destination qemu has disk with same id.
