Re: [Pacemaker] Fencing of KVM virtual machines
Hi all, I've running several pacemaker clusters in KVM virtual machines (everything based on Debian 6) and now it's up to configure fencing... I've found that I have to use fence-virt for that task (http://www.clusterlabs.org/wiki/Guest_Fencing) but it seems that it only will work in case my VMs are on a single host system. Is anybody of you using fence-virt when the VMs are on different hosts? And can anybody explain how to compile and install fence-virt on a Debian 6 system? Thanks a lot!

I've never set it up to do what you say, but I know it can. Lon: are there docs on this anywhere? Is anybody of you using fence-virt when the VMs are on different hosts?

We use: primitive stonith-virtNodeY stonith:external/libvirt \ meta failure-timeout=1min \ op monitor interval=60 \ params hostlist=virtNodeY hypervisor_uri=qemu://xxx.ipax.in/system You might need some ssh keys installed to allow passwordless login, but i don't know for certain anymore. Maybe, it directly talks to the hypervisor via a dedicated port.
