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.
