Ubuntu server eth0 renamed to eth1

I am running an Ubuntu server(9.04) virtual machine(virtualbox) on my computer at work and one night Win 7 rebooted after some security updates. After bringing the VM back up again the network didn't work.

The only thing I can see in the dmesg log is:

[] eth0: registered as PCnet/FAST III 79c973
[] udev: renamed network interface eth0 to eth1

My /etc/network/interfaces looks like:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

The iconfig shows only lo interface.

If I try:

sudo ifup eth0 
SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
...............

sudo ifup eth1
Ignoring unknown interface eth1=eth1

I am not a ubuntu geek, just use it as a git repository, any help to bring the network up again will be appreciated.

Solution 1:

Perhaps mac address or driver has changed for the network card.

Remove /etc/udev/rules.d/*-persistent-net.rules and reboot vm.

Solution 2:

Edit "/etc/udev/rules.d/70-persistent-net.rules".
