Subject: [ovirt-devel] snapshot for LVM2 Volume
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 :
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 ?
Who will support your patched ovirt-3.1?
The best fix is to upgrade to the latest stable version, ovirt 3.5.
