Heyall, We have a use case where a host should self-fence (and all VMs should die) if it doesn't hear back from a heartbeat within a certain time period. Lots of ideas were floated around where libvirt could take care of killing VMs or a separate service could do it. The concern with those is that various failures could lead to _those_ services being unavailable and the fencing wouldn't be enforced as it should.
Ultimately, it feels like Qemu should be responsible for this heartbeat and exit (or execute a custom callback) on timeout. Does something already exist for this purpose which could be used? Would a generic Qemu-fencing infrastructure be something of interest? Cheers, F.
