[libvirt] [PATCH] lxc: Add virCgroupSetOwner()

[Stephan Sachse]

this patch works for me. container is starting fine. but a login
(ssh/console) is not possible.

host: centos6
kernel: 3.13.2
libvirt: 1.2.1 (+ lxc: Add virCgroupSetOwner())

container logs says

agetty[38]: /dev/tty1: cannot get controlling tty: Operation not permitted
agetty[38]: /dev/tty1: cannot get controlling tty: Operation not permitted
agetty[38]: /dev/tty1: cannot set process group: Inappropriate ioctl for device

in my container:

# ls -la /dev/
total 4
drwxr-xr-x  3 root root  320 Feb 14 10:06 .
dr-xr-xr-x 20 root root 4096 Feb 13 10:06 ..

lrwxrwxrwx  1 root root   10 Feb 14 10:06 tty1 -> /dev/pts/0
crw-rw-rw-  1 root root 1, 9 Feb 14 10:06 urandom
crw-rw-rw-  1 root root 1, 5 Feb 14 10:06 zero

# ls -la /dev/pts/
total 0
drwxr-xr-x 2 root root      0 Feb 14 10:06 .
drwxr-xr-x 3 root root    320 Feb 14 10:06 ..
crw--w---- 1 root root 136, 0 Feb 14 10:07 0
crw-rw-rw- 1 root root   5, 2 Feb 14 10:07 ptmx

"chgrp tty /dev/pts/0" and then "exec /sbin/init
systemd.log_level=debug" has no effect. still the same error "cannot
get controlling tty: Operation not permitted"
