Re: [libvirt-users] non failover equivalent to "virsh migrate --copy-storage-all"

Yes - 'virsh blockcopy' can be used for creating a live copy of storage without wasting time copying memory state. That said, blockcopy is still waiting for a qemu 2.4 feature of persistent bitmaps before it can work with non-transient domains (that is, in order to make the copy operation restartable, which is necessary for a persistent domain, we need more help from qemu, as well as patches to libvirt to use that new qemu feature). So for now, you will have to temporarily undefine your domain before doing the blockcopy; you may also have to manually coordinate quiescing the disks through the guest agent if you want your backup to be bootable from a stable point in guest I/O (the copy you are creating via migration is equivalent to what you get when you yank the power cord; the disk may have unflushed pending I/O that you lose, unless you involve the guest agent to quiesce data operations).
