Hello Everyone,
We are just adopting the pacemaker stack to offer our voip and db

My direct and general question is, if we install the HA stack with a
virtualization software

I forgot to ask, for creating an asymmetric cluster, do the services

be installed on all the nodes. And finally is assymetric active/active?

question is, which of the virtual machine platforms out there
play nicer with a
pacemaker cluster (i.e. support things like stonith): KVM, XEN, or VMWare.

It doesn't however, I did mention that in *addition* to quorum support using

Could you show the output of:
