We are using the latest hot fixes with xencenter 6.0 including the one mentioned below. What we noticed was that the openvswitch was running in user mode (for the default xencenter 6.0) installation ! We manually pulled in ovs sources and installed it as kernel module and things are much better n

We are having performance issues with XEN as opposed to VMWARE. Pls take a look at the following cases (OVS - open vswitch, Bridge - native linux bridging) Case 1 (no VM guest tagging):VM1 VNIC1 (no tag) --- OVS ---(vlan X) --- PNIC1--(vlan X)- PNIC2 (vlan
