Changing mac address in VMware

In Centos:
1. Edit old mac HWADDR=XX:XX:XX:XX:XX:XX in the file /etc/sysconfig/network-script/ifcfg-eth0.
2. Check the file /etc/udev/rules.d/70-persistent-net.rules. Make sure it has no sections with old mac. If it has, delete them.

# PCI device 0x1022:0x2000 (pcnet32) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="XX:XX:XX:XX:XX:XX", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
 
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="YY:YY:YY:YY:YY:YY", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

Delete first section with old mac and change "eth1" to "eth0" in second section.

3. Check links

cd /sys/class/net
ls -l
ip link set dev eth1 name eth0

This will change link from eth1 (old nic) to eth0

4. Restart network

service network restart
