Openstack 虚拟机 CPU类型不匹配导致虚拟机创建启动慢的问题

Openstack以qcow2为镜像创建实例，实例的CPU类型自动分配为EYPC，但是查看计算节点CPU类型为Inter，因此在nova配置中设置计算节点的cpu_mode[libvirt]virt_type=kvmcpu_mode=host-model以下引入Openstack官网的配置信息描述：virt_type = kvm (StrOpt) Libvirt domain type (valid options are: kvm, lxc, qemu, uml, xen and parallels)cpu_mode = None (StrOpt) Set to “host-model” to clone the host CPU feature flags;to “host-passthrough” to use the host CPU model exactly; to “custom” to use a named CPU model; to “none” to not set any CPU model. If virt_type=“kvm|qemu”, it will default to “host-model”, otherwise it will default to “none"cpu_model = None(StrOpt) Set to a named libvirt CPU model (see names listed in /usr/share/libvirt/cpu_map.xml). Only has effect if cpu_mode=“custom” and virt_type=“kvm|qemu”
