同步操作将从 src-anolis-os/libvirt 强制同步,此操作会覆盖自 Fork 仓库以来所做的任何修改,且无法恢复!!!
确定后同步将在后台操作,完成时将刷新页面,请耐心等待。

Subject: [PATCH] cpu_map: Disable cpu64-rhel* for host-model and baseline
These ancient RHEL-only CPU models should not really be used by any CPU
definition created by libvirt. We keep them just for backwards
compatibility with domains which might still be using them.
