[Qemu-devel] [PATCH 1/2] sheepdog: fix snapshot tag initialization


From: Liu Yuan
Subject: [Qemu-devel] [PATCH 1/2] sheepdog: fix snapshot tag initialization
Date: Thu, 6 Jun 2013 19:57:28 +0800

This is an old and obvious bug. We should pass snapshot_id to the
tag. Or simple command like 'qemu-img snapshot -a tag sheepdog:image' will fail
