I suspect that getVmStats and getSpmStatus simply do not take the hostmonitoring lock, and I don't see anything wrong in that. Note that during 006_migration, we set only a mere migration network, not the management network. This operation should not interfere with Engine-Vdsm communication in any way; I don't yet understand why you suspect that it does. _______________________________________________ Devel mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/devel
