Hi Pierre,
you could try to double check the /etc/cluster/fence_xvm.key if it is
really the same on the host and the guests.
Then you could try the omping tool to test that multicast is working
correctly.

Miroslav

Hi all,
I am trying to get a working fencing device on a single Proxmox 8 host
(not using the Proxmox tools) with fence_virtd and fence_virt/vxm. I
can't get the command
# fence_xvm -o list
to output anything, it keeps failing via timeout despite many attempts
at finding the fault. The exact return message is:
Timed out waiting for response
Operation failed
I am trying to configure it using the multicast Listener with the
Libvirt backend. All settings were left to defaults except the
listening interface which was set to the Linux bridge connecting the
host and the guests. The fence_xvm.key file was copied in the
/etc/cluster/ directory on the host and on the guests.
I followed this:
https://projects.clusterlabs.org/w/fencing/guest_fencing/
<https://projects.clusterlabs.org/w/fencing/guest_fencing/> which
didn't work,
then this:
https://kevwells.com/it-knowledge-base/how-to-install-cluster-fencing-using-libvert-on-kvm-virtual-machines/
<https://kevwells.com/it-knowledge-base/how-to-install-cluster-fencing-using-libvert-on-kvm-virtual-machines/> which
also didn't work.
I read the man pages for fence_virt, fence_xvm, fence_virtd and
fence_virt.conf.
I read the README and doc files in "agents/virt" and "agent/virt/docs"
from the source repository.
I am at a loss here. Is there a better guide out there (or more up to
date)?
Thanks.
