Re: [libvirt-users] lxc-enter-namespace error: security model cannot be entered.

Hi Guys, I started a lxc container with libvit in ubuntu Operating system, and succeed using lxc-enter-namespace to enter the namespaces and security context of the container. But when I do the same thing in debian OS, It reported an error, with details as following: root@debian:/etc# vir list Id Name State ---------------------------------------------------- 4424 instance-00000007 running 25913 instance-00000008 running root@debian:/etc# vir dumpxml 4424 <domain type='lxc' id='4424'> <name>instance-00000007</name> <uuid>f1ce5360-bb5e-4cfc-b5ef-d05f8db52618</uuid> <memory unit='KiB'>1048576</memory> <currentMemory unit='KiB'>1048576</currentMemory> <vcpu placement='static'>3</vcpu> <resource> <partition>/machine</partition> </resource> <os> <type arch='x86_64'>exe</type> <init>/sbin/init</init> <cmdline>console=tty0 console=ttyS0</cmdline> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/lib/libvirt/libvirt_lxc</emulator> <filesystem type='mount' accessmode='passthrough'> <source dir='/opt/stack/data/nova/instances/f1ce5360-bb5e-4cfc-b5ef-d05f8db52618/rootfs'/> <target dir='/'/> </filesystem> <interface type='bridge'> <mac address='fa:16:3e:3a:c6:11'/> <source bridge='br100'/> <target dev='veth0'/> <filterref filter='nova-instance-instance-00000007-fa163e3ac611'/> </interface> <console type='pty' tty='/dev/pts/1'> <source path='/dev/pts/1'/> <target type='lxc' port='0'/> <alias name='console0'/> </console> </devices> <seclabel type='none'/> </domain> root@debian:/etc# vir lxc-enter-namespace 4424 /bin/sh/ libvirt: error : argument unsupported: Security model cannot be entered Is there anything that needs to be configured in debian OS for using the 'lxc-enter-namespace' interface?
