Hi Fabrice, What are you think about this patch? Are you have a comments? If you accept it, I'll try to fix the race
condition on snapshot writing. Regards From: address@hidden
[mailto:address@hidden On Behalf Of Hi all, It's the new patch for the multiple snapshot support for the
VMDK format. I rewrote the previous one according to the new multiple
snapshots concept, introduced by Fabrice. The snapshots can be created with standard way: qemu-img create –b base-image.vmdk –f vmdk
snapshot-img-001.vmdk We can create the snapshots chain in this way. The patch include also the 'CID' protection that defined by
the VMDK format. The CID is a value updated on the first write every time the
virtual disk is opened. P.S. Fabrice, I used the bdrv_pread() and
bdrv_pwrite(), as you advised me.
Regards,
