[PVE-User] implementing openvswitch

I have a problem when implementing Open vSwitch. When I configure my one 
node to use ovs, all cluster work is heavily disturbed - GUI lacks, 
commands take forever to reply.
As soon as I take proxmox interface down, everything normalizes.

Switches support multicast and IGMP snooping is turned off. Multicast 
ping (*ssmpingd* on one node and *asmping* on second node) works 
fluently on both directions.

*Should cluster work when all of the nodes are using Linux bridges and 
one is using ovs?* This node has been a cluster member and has used 
Linux bridges as well.

*On all nodes:*
- running kernel: 2.6.32-34-pve
- proxmox-ve-2.6.32: 3.3-139 (running kernel: 2.6.32-34-pve)
- pve-manager: 3.3-5 (running version: 3.3-5/bfebec03)

*On this node:*
   Installed: 2.3.0-1

OVS is configured properly, at least I think so, because I have 
connectivity between hosts and I can ping and ssh between nodes, ISCSI 
connection is up and running.

Any directions or ideas are helpful!
