[libvirt-users] virsh migrate --copy-storage-inc

Hello, I use libvirt on machines without shared storage. My VM's have all one qcow2-disk, with the same name as the VM. When I want to migrate a VM, I check if there is an qcow2 image on the other host with that name. When that's not the case, I copy the image using rsync first. If the image excist, I don't do that, and I think that "--copy-storage-inc" will do it. But I don't know how intelligent "--copy-storage-inc" is. I use LVM inside the VM's, and it's possible that I have changed the size of a volume for example. My questions: Is "--copy-storage-inc" intelligent enough for such tasks? Is there documentation what is done during migration? Is it using rsync? Is it possible to make the migration process more verbose? Is what I do a good way? With regards, Paul van der Vlis BTW: this is what I do, sometimes the lines are broken wrong: ----------- # Rsync image when not on the other host: if test `ssh $other "if test -e /data/$vm.qcow2; then echo ja; else echo nee; fi"` = "nee"; then echo "rsync..." rsync /data/$vm.qcow2 $other://data/$vm.qcow2 if test $? = 0; then echo "gelukt"; else echo "niet gelukt"; exit; fi fi # migrate echo "migrate..." virsh migrate --live --p2p --tunnelled --copy-storage-inc --persistent --undefinesource --verbose $vm qemu+ssh://$other/system if test $? = 0; then echo "gelukt"; else echo "niet gelukt"; exit; fi ----------- -- Paul van der Vlis Linux systeembeheer Groningen https://www.vandervlis.nl/
