在全新安装 Lubuntu 18.04.2 LTS 64 位后，我遇到了关机/重启问题。系统在特定点挂起。
停用 plymouth（“noplymouth”而不是“quiet splash”）后，我能够找出系统挂起的位置。最后的条目如下：
systemd-shutdow [1]: 12 output lines suppressed due to rate limiting
systemd-shutdown [1]: Syncing filesytems and block devices
systemd-shutdown [1]: Sending SIGTERM to remaining processes
systemd-journald [284]: Received SIGTERM from PID 1 (systemd-shutdown)
systemd-shutdown [1]: Sendig SIKILL to remaining processes ...
systemd-shutdown [1]: Unmountig file systems
EXT4-fs (sdc1): re-mounted. Opts: block_validity,barrier,user-xattr,acl,errors=remount-ro
systemd-shutdown [1]: All filesystems unmounted
systemd-shutdown [1]: Deactivating swaps
systemd-shutdown [1]: All swaps deactivated
systemd-shutdown [1]: Deactivating loop devices
systemd-shutdown [1]: All loop devices detached
systemd-shutdown [1]: Detaching DM devices
kvm: exiting hardware virtualization
因此 kvm 似乎是罪魁祸首。
有人知道该怎么办吗？
整个事情有点奇怪，因为我有一个完美的系统，一切都应该完美运行。
