Mandatory args:
-n,--name container name, used to as an identifier for that container from now on
Optional args:
-p,--path path to where the container rootfs will be created, defaults to /var/lib/lxc. The container config will go under /var/lib/lxc in that case
-c,--clean clean the cache
-R,--release openmandriva2013.0/cooker/rosa2012.1 release for the new container. if the host is OpenMandriva, then it will default to the host's release.
-4,--ipv4 specify the ipv4 address to assign to the virtualized interface, eg. 192.168.1.123/24
-6,--ipv6 specify the ipv6 address to assign to the virtualized interface, eg. 2003:db8:1:0:214:1234:fe0b:3596/64
-g,--gw specify the default gw, eg. 192.168.1.1
-G,--gw6 specify the default gw, eg. 2003:db8:1:0:214:1234:fe0b:3596
-d,--dns specify the DNS server, eg. 192.168.1.2
-P,--profile Profile name is the file name in /etc/lxc/profiles contained packages name for install to cache.
-A,--arch Define what arch the container will be [i586,x86_64,armv7l,armv7hl]
