我尝试在 Virtualbox 中的 Centos 8 上安装 openstack 计算服务。我遵循以下说明：https://docs.openstack.org/nova/yoga/install/compute-install-rdo.html
但是当我尝试启动服务时出现错误：
vsystemctl status libvirtd.service openstack-nova-compute.service

怎么修复？
由于我在 VM 上安装，因此我将 libvirt 配置为使用 QEMU 而不是 KVM。
etc/nova/nova.conf
[libvirt]
# ...
virt_type = qemu
