cluster virtual IP intermittent problem

[w3859189]

rhel5.5 ， rhcs cluster ，and xen kernel .
now the cluster is running . the service ccsd .cman ,and rgmanager does work on both of the cluster member host.
now I have a connecting problem when access the cluster virtual IP from different subnet clients. the clients in the different subnet with the cluster virtual iP access the VIP , the connection is intermittent ,while the clients in the same subnet of the VIP ，access the cluster VIP ，the connection is always on.

could anybody tell me , does the xen kernel has impacts to the cluster , or is this only a networking problem not a system problem?

I monitor the switch mac table, find that , the mac of eth0 is always changing .
so maybe it is xen kernel problem. I refer to some xen materials , the eth0 is a virtual adapter .and the original physical adapter eth0 is renamed as pth0 and works as a bridge .

so how could I fix a mac address to eth0 ?

hi I've encountered a similar problem - have you had a solution to this ? what logs did you look at to analyse the problem..

The default gw is what makes your computer accessible from other subnets.

By the way, our HA clusters work with heartbeat and drbd, so I cannot help with rhcs.
