Re: Live migration to another volume at the same host

What I did now is this: virsh dumpxml kvm25 > /home/paul/kvm25.xml virsh undefine kvm25 virsh blockcopy kvm25 --pivot --verbose --format=qcow2 \ --path /data/kvm25.qcow2 \ --dest /data2/kvm25.qcow2 virsh dumpxml kvm25 > /home/paul/kvm25.xml2 virsh define /home/paul/kvm25.xml2 This all looks nice. The only thing I did not like is that the username and group of /data/kvm25.qcow2 is still "libvirt-qemu". Normally this changes to "root" when the image is not in use. But not in this case. What I found interesting is that the destination file is a bit smaller then the original file. Maybe it does some clean-up? root@kvms12:/data# ls -l /data/kvm25.qcow2 -rw-r--r-- 1 libvirt-qemu libvirt-qemu 11531190272 jun 12 00:41 /data/kvm25.qcow2 root@kvms12:/data# ls -l /data2/kvm25.qcow2 -rw------- 1 libvirt-qemu libvirt-qemu 11277369344 jun 12 01:05 /data2/kvm25.qcow2 root@kvms12:/home/paul# diff /home/paul/kvm25.xml /home/paul/kvm25.xml2 34c34 < <source file='/data/kvm25.qcow2'/> --- I've used "--format=qcow2" and I think that does the trick ;-) I did not create an image on the destination.
