No objections to the patch that was committed, but FYI there is an improvement that can be done to it. If you run 'virsh domjobinfo $GUEST' while migration is running it tells you the progress of migration. It gives overall progress, and memory progress. The APi was designed to allow us to report storage progress too. To wire this up look at the method qemuDomainWaitForMigrationComplete where it updates the priv->jobInfo variables. You'll also need to add extra params to the qemuMonitorGetMigrationStatus() method to return the disk processed/remaining/total stats virsh should already be able to report this data once the QEMU driver is wired up Regards, Daniel -- |: Red Hat, Engineering, London -o-
