Container rootfs and config have been created.

Edit the config file to check/enable networking setup.

The temporary root password is stored in:

        '/var/lib/lxc/myhost1/tmp_root_pass'

The root password is set up as expired and will require it to be changed

at first login, which you should do as soon as possible.  If you lose the

root password or wish to change it without starting the container, you

can change it from the host by running the following command (which will

also reset the expired flag):

        chroot /var/lib/lxc/myhost1/rootfs passwd
