One bird VM (HA cluster) or two bird VMs (iBGP).

[Volodymyr Pidgornyi]

Hi.

You would not install single bird instance on vmware HA cluster since 
you'll get sessions flaps when instance restart on falures. Right way is 
to run two different instances on different cluster nodes with HA 
deactivated for these instances and setup sessions from each bird instance.
