I had a customer today email me that they created a Ubuntu template within Lab Manager, and after deployment; the VM’s eth0 became eth1 and they could not figure out how to fix it.

after doing some digging, I removed the following file from the template and shut down the template:

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

I then deployed from the template and the default network device stayed at eth0 without incrementing.
