CentOS7上如何支持安装CentOS8 VM

环境

• 宿主机：CentOS 7.5
• VM: CentOS 8.1

查看支持os

osinfo-query os

当前环境默认不支持CentOS8/RHEL8，需做如下操作:

# osinfo-db 需更新至osinfo-db-20190805-2
yum install osinfo-db-tools osinfo-db

报错处理

ERROR ‘virConnect’ object has no attribute ‘baselineHypervisorCPU’

将 libvirt-python-3.9.0-1 升级至 libvirt-python-4.5.0-1 即可解决
