From: Daniel Henrique Barboza <danielhb@linux.vnet.ibm.com> This patch changes the vcpu verification when editing a turned off VM, if the VM has a topology set, to comply with the current libvirt schema: vcpus must be a multiple of the 'threads' value. Unit tests were adapted to reflect these changes.
