Yes, I had the checkbox marked when I made the template.

Hi Berger,
Have you sealed the template? if you didn't sealed the template on creation, then your new VM has the same ifcfg-eth0 settings as your origin VM.
In order to avoid this, you need to check the 'Seal Template (Linux only)' checkbox in the New Template dialog.
Cheers)

Hello Sandy,

i had the same issue and the cause was cloud-init running again at
boot even if Run-Once hasn't been selected as boot option. The way i'm
using to solve the problem is to remove cloud-init after the first
run, since we don't need it anymore.

In case also disabling is enoug:

touch /etc/cloud/cloud-init.disabled
