Creating CentOS template for vSphere ESX

I came across of online resources for creating CentOS template for vShphere/ESS, keeping here for self notes:

mentioned on this blog ( - Before you convert the VM to a template.

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

sed -i ‘/HWADDR*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

sed -i ‘/UUID*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

(This also applies to SLES 11 SP2 (use /etc/sysconfig/network/ifcfg-eth)
