Fixed In Version: openstack-nova-14.0.9-2.el7ost
Doc Type: Bug Fix
Doc Text:
Prior to this update, QEMU (also known as TCG) guests had an issue where the `guest.get_vcpu_info` method was throwing an exception indicating that 0 were vCPUs used on the host, regardless of how many guests were running. Consequently, this caused the 'get_available_resources' method to report incorrect vCPUs used values for the Compute node. This meant it was overcounting resource consumption for plain QEMU guests, as they can only ever consume 1 pCPU of time, regardless of vCPU count. With this update, if a host does not report detailed vCPU usage from libvirt, then it should default to reporting 1 vCPU per guest, so that the 'vcpus_used' field reports some reasonably meaningful data on host CPU usage. As a result, libvirt does not report that 'cpu affinity is not supported' when guests are running in TCG.
