[lxc-users] Full network device access in the container

[Piotr R]

The host is running stripped down version of Red Hat 6.4 and container is
running a bit different stripped down version of Red Hat 6.4. Both guest
and the host are customized quite substantially so it would be difficult to
list all the modifications. The container was created by extracting root
file system from an ISO. The root file system is distributed in an ISO in
an image file. I extracted the image file from the ISO, loopback mounted
the image an copied entire file system to a new directory. I did not use
lxc-create.

Following your advice I attempted to disable udev startup by the following
change:
--- /etc/rc.d/rc.sysinit.bak 2013-12-20 19:35:29.000000000 +0000
+++ /etc/rc.d/rc.sysinit 2014-01-16 19:08:34.527904279 +0000
@@ -137,7 +137,6 @@
 nashpid=$(pidof nash 2>/dev/null)
 [ -n "$nashpid" ] && kill $nashpid >/dev/null 2>&1
 unset nashpid
-/sbin/start_udev

 # Load other user-defined modules
 for file in /etc/sysconfig/modules/*.modules ; do


This change get rid of udevd error message as expected but I still can't
get console prompt. I would greatly appreciate any suggestions about where
look for the problem.

BTW I don't think I understand how all the mounts are done in the
container. For example at which point and in what context the fstab file
specified by lxc.mount is used? Are the mounts done before or after
chrooting to the container?
