Its way more trouble to update this to a newer version of qemu than it is to backport the two additional features we need. Signed-off-by: Brett Mastbergen <bmastbergen@untangle.com>

Subject: [PATCH 08/12] VMDK: move 'static' cid_update flag to bs field
|
|
|
|
Cid_update is the flag for updating CID on first write after opening the
|
|
image. This should be per image open rather than per program life cycle,
|
|
so change it from static var of vmdk_write to a field in BDRVVmdkState.
