'sshd' template installed
'vm2' created

2) When i did
lxc-start -n vm2 -f /home/nishant/vm2//lxc-macvlan.conf /bin/bash
 After this command the terminal hangs....

3)lxc-ls
   vm2

4)lxc-info -n vm2
vm2 is stopped

am i right in executing command or is there something i m missing in
executing......
Plz help me.

The only change i did is copied conf file to loc /home/nishant/vm2 and
changed lxc.rootfs=/home/nishant/vm2 and changed the lxc.utsname = vm2.
Do i need to make some changes in /etc/fstab and creating control groups.





Regards,
Nishant.
