I'm using VirtualBox 4.1.22 and have a Opensuse 12.1 VM. When I clone it without any changing (even not MAC address), the cloned version doens't work propperly. It boot for a long time and give message in terminal like this
Welcome to emergency mode. Use "systemctl default" or ^D to enter default mode. Give root password for login:. When I ran this I shut down the original one to avoid any conflict but it doesnl't help. If I change to default mode, it just reboot and give that message again. When I change some network setting via Yast and save, it will reboot immediately. I tried to run the cloned version on another physical machine but still got the same problem. The cloning is suppose to copy every thing in the VM, and the cloned version should just work exactly as original one does. I really don't understand why it just won't work.
What wrong did I do? Any one have similar problem? I saw some people complain about hard drive UUID problem. I didn't got the HDD error but it simply doesn't work.
