I think you've just fingered the root underlying issue.

Virtualization adds an entire additional layer of complexity. Rivendell is an inherently real-time application, whereas most hypervisors are optimized for non-real-time workloads. I strongly suspect that you have some sort of priority inversion going on between the server and guest instances.

What kind of hypervisor are you using, and how do you have it tuned? KVM in particular can become quite flaky if you ask it to run more guest instances than there are CPU cores available to service them.

Cheers!
