XCP 0.5.0 again, I don't think this really counts as a bug, but it does
seem to be a change in behavior (undocumented as far as I can tell) from
0.1.1.
When migrating VMs between 2 hosts, 0.5.0 seems to be rather pokey about settling out the memory changes. Since the XCCS load balancer runs up to 5 rebalance passes every time it's called, the load balancer may run the second pass before the hosts are settled out from the first. This means that passes 2-5 may produce less than accurate results in balance. I'll adding a slight delay to each load balancer pass for the 0.5.1 release. -- Vern Burke SwiftWater Telecom http://www.swiftwatertel.com Xen Cloud Control System http://www.xencloudcontrol.com _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
