[lxc-users] failed to start container on centos

[Mingjiang Shi]

Hi Alvaro,
Thanks for your reply and suggestion.  It still doesn't work.

[root at devmachine rootfs]# service cgconfig status
Running

[root at devmachine rootfs]# service libvirtd status
libvirtd (pid  2671) is running...

[root at devmachine rootfs]# lxc-start -n c1 -d
lxc-start: command get_cgroup failed to receive response

[root at devmachine rootfs]# lxc-start -n c1
lxc-start: unknown capability mac_admin
lxc-start: failed to drop capabilities
lxc-start: failed to setup the container
lxc-start: invalid sequence number 1. expected 2
lxc-start: failed to spawn 'c1'

Any idea about this error message: "lxc-start: unknown capability
mac_admin"?
