[libvirt] [PATCH 0/2] [for-5.7.0] qemu: Honor qemu's request to use all vCPU props

Posted by Peter Krempa 6 years, 5 months ago

qemu documents that we should pass in all fields of
'CpuInstanceProperties' back when hotplugging cpus, but we didn't do
that. It turns out that qemu wanted to add new fields which were
mandatory and thus broke the interop with libvirt.

Let's honor their reques.

Peter Krempa (2):
  qemu: Extract and store vCPU properties as qemu returned them
  qemu: command: Use all vCPU properties when creating args for vCPU
    hotplug
