Hi Gao,

I checked the output of "lxc-checkconfig" command and it showed

--- Namespaces ---

Namespaces: enabled

Utsname namespace: enabled

Ipc namespace: enabled

Pid namespace: enabled

User namespace: missing

Network namespace: enabled

Multiple /dev/pts instances: enabled

Here it shows that User namespace support is missing. I tried to check for Namespaces Support in kernel menuconfig. It has support for following namespaces only:

--- Namespaces support

[*] UTS namespace

[*] IPC namespace

[*] PID Namespaces

[*] Network namespace

There is no User Namespace support. So do I need to patch the kernel for user namespace support? What should I do in order to get user namespace working?

Following are my system details:
OS: Fedora 19
Kernel: 3.9.5

Thanks and Regards,

Saurabh Deochake.
