I am using ovirt 3.1 in iSCSI environment . I fixed some bug of vdsm.. In this version , snapshot only for disk, not memory . When I try to take snapshot for a running vm , error log shown in vdsm.log libvirtError: unsupported configuration: source for disk 'vda' is not a regular file; refusing to generate external snapshot name After reading libvirt's mail archive, I found a patch in this mail : http://www.redhat.com/archives/libvir-list/2011-November/msg00843.html but in vdsm environment, every image from iSCSI server is a link file or a dev file , not a regular file . Do you have any solution ? Or I should patch more code , something like memory snapshot ?
