Hi!
I am hitting an racing issue with migration.
I migrate a guest from one machine to another using libvirt:
virsh migrate --live --persistent --undefinesource --copy-storage-all
--verbose --desturi qemu+ssh://legkvm/system --domain chig1
I.e. it copied the full disk which is qcow2, 20G
20 matches
