[lxc-devel] bugs with LXC container : mount and rmmod command

[Elias Olivares]

Hi 


My Lxc configuration file : ( /var/lib/lxc/xxx.1g6.biz /config ) 

lxc.utsname = xxx.1g6.biz 
lxc.tty = 4 
lxc.pts = 1024 
lxc.network.type = veth 
lxc.network.flags = up 
lxc.network.link = br0 
lxc.network.name = eth0 
lxc.network.mtu = 1500 
#lxc.mount = 
lxc.rootfs = /mnt/vmr1/xxx.1g6.biz 
lxc.cgroup.devices.deny = a 
# /dev/null and zero 
lxc.cgroup.devices.allow = c 1:3 rwm 
lxc.cgroup.devices.allow = c 1:5 rwm 
# consoles 
lxc.cgroup.devices.allow = c 5:1 rwm 
lxc.cgroup.devices.allow = c 5:0 rwm 
lxc.cgroup.devices.allow = c 4:0 rwm 
lxc.cgroup.devices.allow = c 4:1 rwm 
# /dev/{,u}random 
lxc.cgroup.devices.allow = c 1:9 rwm 
lxc.cgroup.devices.allow = c 1:8 rwm 
lxc.cgroup.devices.allow = c 136:* rwm 
lxc.cgroup.devices.allow = c 5:2 rwm 
# rtc 
lxc.cgroup.devices.allow = c 254:0 rwm 

# lxc-version 
lxc version: 0.6.3
