Another option would be to use SBD for fencing if your hypervisor can
provide uncached shared storage:

https://github.com/ClusterLabs/sbd

This is what we usually use for our test setups here, both with
VirtualBox and qemu/kvm.

fence_vbox is actively maintained for sure, but we'd need to narrow down
what the correct changes would be to make it work in your
environment.

Trying to use a dummy fencing agent is likely to come back to bite you,
the cluster will act very unpredictably if it thinks that there is a
fencing option that doesn't actually work.

For fence_vbox, the best path forward is probably to create an issue
upstream, and attach as much relevant information about your environment
as possible:
