Hi zhangzhang, Did you check your SELinux settings? Is it set to enforcing? I faced the same error on CentOS 6.3. My SELinux was disabled. I just set it to enforcing and rebooted the system. I could create a container after reboot. Thanks and Regards, Saurabh. On Mon, Mar 25, 2013 at 12:29 PM, 张章 <zhang_zhang@live.com> wrote:

hi all, I am using lxc with libvirt. But I can't boot lxc container by libvirt 1.0.3(libvirt 0.9.8 works) . Below is my environment. Do I miss something?

lxc1.xml: <domain type='lxc'> <name>lxc1</name> <memory>1024000</memory> <cputune> <shares>100</shares> </cputune> <os> <type>exe</type> <init>/bin/sh</init> </os> <devices> <console type = 'pty'/> </devices> </domain>

I used virsh -c lxc:/// create lxc1.xml and got the following error: 2013-03-25 06:54:17.620+0000: 1: info : libvirt version: 1.0.3 2013-03-25 06:54:17.620+0000: 1: error : lxcContainerMountBasicFS:563 : Failed to mount /selinux on /selinux type selinuxfs flags=e opts=(null): No such device 2013-03-25 06:54:17.620+0000: 10668: info : libvirt version: 1.0.3 2013-03-25 06:54:17.620+0000: 10668: error : virLXCControllerRun:1468 : error receiving signal from container: Input/output error

Can anyone help me? Thanks a lot!
