I don't think that's it - if you look at the logs provided, you can see that the storage was apparently fully copied after 49 seconds. There was then 5 minutes where neither the disk or memory processed numbers increased, before memory copying started. So there's something fishy going on there, whether just bogus stats reporting by qemu or a genuine delay/hang somewhere Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
