启动容器时出现以下错误？可能是内存设置问题吗？
$ lxc-start -n vm1
// error
lxc-start: cgroup is not mounted
lxc-start: failed to setup the cgroups for 'vm1'
lxc-start: failed to setup the container
lxc-start: invalid sequence number 1. expected 2
lxc-start: failed to spawn 'vm1'
答案1
您需要安装 cgroup 文件系统。如果这是 RHEL/CentOS，请确保您已libcgroup安装。
