lxc-start：生成失败

Question

我尝试按照以下步骤从这里创建和启动 lxc 容器：https : //help.ubuntu.com/lts/serverguide/lxc.html

我的主机运行的是最新的 64 位 Precise (12.04)，我正在尝试启动一个精确的容器。我创建了这样的容器：

sudo lxc-create -t ubuntu -n precise -- -r precise

它似乎成功完成。当我尝试开始时，我得到：

$ sudo lxc-start -n precise
lxc-start: failed to spawn 'precise'

和 kern.log 说：

Answer 1

我认为该软件包cgroup-lite未安装。尝试：

$ sudo apt-get install cgroup-lite
$ sudo cgroups-mount

并再次运行容器。
