--- fixes: - | When instantiating an instance based on an image with the metadata hw_vif_multiqueue_enabled=true, if flavor.vcpus is less than the limit of the number of queues on a tap interface in the kernel, nova uses flavor.vcpus as the number of queues. if not, nova uses the limit. The limits are as follows: * kernels prior to 3.0: 1 * kernels 3.x: 8 * kernels 4.x: 256
