If you keep getting eth1 instead of eth0 as your main ethernet interface on a (newer) linux template/clone in a virtualized environment it's most likely because your udev rules is in affect and creates a new eth1 since eth0 is already defined and bound to the clone/template source's MAC address.
Edit the rules files
This can be fixed in a couple of ways (in your template/clone source image):
1) You can delete the 'SUBSYSTEM' line in your /etc/udev/rules.d/70-persistent-net.rules:
Edit the rules files
vi /etc/udev/rules.d/70-persistent-net.rules
Delete the SUBSYSTEM line(s), feel free to also delete the comment about PCI device just above:
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:4b:05:e0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
2) A more dirty hack would just be to delete the /etc/udev/rules.d/70-persistent-net.rules file and create a directory named as the file. This tip is taken from six degrees of fredom blog (link):
rm /etc/udev/rules.d/70-persistent-net.rules
mkdir /etc/udev/rules.d/70-persistent-net.rules
