lxc-start: falha ao gerar

Question

Eu tentei seguir as etapas para criar e iniciar um contêiner lxc a partir daqui: link

Meu host está executando um Precise (12.04) atualizado de 64 bits e estou tentando iniciar um contêiner preciso. Eu criei o contêiner assim:

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

e pareceu completar com sucesso. Quando tento começar, obtenho:

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

e kern.log diz:

Answer 1

Acho que o pacote cgroup-lite não está instalado. Experimente:

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

E execute o contêiner novamente.
