I've got a Centos 5.8 box that I use for testing Xen VMs. I'm trying to setup some Centos 6.2 hosts in a high availability situation. I've tried the pacemaker route and couldn't get the connection established, so thought I'd try the RH-preferred methods. Mind you, all of these VMs are on the same host. Using Conga, it seems that I need some sort of fencing device, which doesn't really work in a VM environment. I'm guessing it's the same with command line configuration. Firstly, is it really possible to set up two VMs on the same machine to do HA? I can't see why not, but I'm not the best source of knowledge on any of this. Secondly, is there a useable fencing device that would work in a virtual environment for me to test with? I'd really like to avoid fencing altogether, even once in production, but every thing I read suggests against that. Any type of reply would be appreciated. steve campbell _______________________________________________ CentOS-virt mailing list CentOS-virt@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos-virt
