I have tried creating a virtual machine using Vmware workstation, installing Ubuntu 7.04 server edition and it is working fine with the bridged network settings. (I didn't installed the vmware tools since I am getting errors. 
) The vm gets a new ip via DHCP and everything works fine. However, when I copied this vm to another machine, the only ip address shown from ifconfig is 127.0.0.1 and it can not find the correct NIC.
I have experienced the same thing many times in the past when I downloaded some linux distro vm appliance. Sometimes the network magically works. I am wondering whether there is a list of things that need to be done to make sure that when the vm is copied to another computer, the network will still work?
BTW: everytime I copy a vm, I always choose to create a new UUID.
Thanks a lot,
/etc/iftab shows: "eth0 mac 00:0c:29:69:be:e5 arp 1"
/etc/network/interfaces shows:
"auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp"
I can understand that udev might think it as a new network device, (I am not familiar with udev at all. ). And I could not find /etc/udev/rules.d/z25_persistent-net.rules
Anyway, if this is the issue, how can I make this new eth0 work?
Thanks,
