This series is getting rather big. The target is to refactor the way libvirt
stores info about vCPUs into a single structure (okay, two structures for the
qemu driver. Part 1 is not yet completely there, well, not even halfway.
Future work will involve fully allocating priv->vcpupids to the maxcpus size
and moving around few other bits of data in cputune and other parts to the new
structure. Yet another follow up work is then to add new APIs for vCPU hotplug,
which will enable adding vCPUs sparsely (useful if you have NUMA).
Since this refactor will result in tracking all vcpu-related data in one struct,
the result will automagically fix a few bugs where we'd end up with invalid
config after vcpu unplug or other operations.
The changes can also be fetched at:
