Copying a parallels linux instance to a new machine – and getting eth1 instead of eth0

Copying a parallels instance is easy as copying the file from one machine to another.

But, this seems to screw up networking. The copied instance starts but a call to ifconfig -a shows no eth0 but a disconnected eth1 instead.

I’m guessing this is because the mac address the new version of parallels is supplying is different.

A way to fix is to edit /etc/udev/rules.d/70-persistent-net.rules

and remove the old card definition, and reassign eth0 to the new card

 

In hindsight a better thing to try would be to set the mac address to that of the original machine before starting the instance on the new machine.
