I've a cluster (active/passive) with two KVM VM with Asterisk and=20 Pacemaker+Corosync. I wonder if anyone tried to use a OpenVox A400P=20 card from a virtual machine. My idea is to have both nodes accessing this card. I don't know if it is possible, I wish that in this scenario when a node is accessing the card, the other don't use it. Of course this is a scenario for testing, but I wonder if I can do this kind of configuration on the cluster over virtual machines.
