Libvirt needs to know when a vCPU is halted. To get this information,
I don't see why upper level management should care about that, a single bit about halted state that can be incorrect at the time it is processed seems of very limited use.
I don't see why, either.
I'm CCing libvir-list and the people involved in the code that added halt state to libvirt domain statistics.
I've posted a libvirt patch to disable query-cpus in the domain stats collection for all architectures other than s390. This should alleviate the problem until we have a better method to obtain arch-specific cpu state.
This is cool, thanks a lot. Btw, I'll follow up this week with a replacement for qemu-cpus in QEMU. Then we can discuss again the best long term strategy for this issue.
