Subject: | [Qemu-devel] New multiple snapshot support for VMDK. |
Date: | Mon, 15 Jan 2007 06:51:01 -0800 |
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, |
