Re: [libvirt-users] move VM disk images between storage pools on the same host

I guess you could use 'virsh vol-download' and 'virsh vol-upload' to move volumes from one place to another, although those APIs still lack the ability to cleanly state whether you are migrating metadata (what the host sees) or contents for conversion into a different format (what the guest sees). At any rate, these commands would be useful on offline disks (and NOT for a disk image in active read-write use by any qemu guest). I think there's a lot of work that could be done to improve matters with how we manage volumes and pools. Meanwhile, live storage migration IS possible, with libvirt 1.0.0 (now out) and qemu 1.3 (which will be released in December, or if you are comfortable building from qemu.git now), via the 'virsh blockcopy' command. This is a publicly archived list, where such disclaimers are unenforceable.
