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 ALTLinux release for the new container. if the host is ALTLinux, then it will defaultto 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

-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 NOT USED YET. Define what arch the container will be [i686,x86_64]
