Hi, I'm trying to create a snapshot on a specific disk by using diskspec option. However, libvirt/virsh seems to ignore it and takes a snapshot of all disks. Am I using this option incorrectly?
In below examples, I'm trying to snapshot only vdb. However even vda is getting snapshotted regardless of diskspec. Is this a known issue?
I'm on CentOS 7.1, libvirtd (libvirt) 1.2.8, virsh 1.2.8
