Maybe the file is corrupted?
造成这个错误的原因是:
由于机器开机状态时,将SElinux的状态信息save在虚拟机中,导致SElinux关闭之后,虚拟找不到对应的label,从而导致vm启动失败。
如果配置配置文件中有selinux相关的配置,将其删除,如果没有,则可能已经保存在vm状态中,将原有的状态删除即可(对应路径/var/lib/libvirt/qemu/save),如下:
~ ls /var/lib/libvirt/qemu/save 13svn.save 14git.save 15samba.save 16lnmp.save 26svn.save centos7.save ? ~ rm /var/lib/libvirt/qemu/save/16lnmp.save ? ~ virsh start 16lnmp Domain 16lnmp started #启动成功!!!
