MAC Addresses

You may want to set a MAC address on a virtual interface manually. This is a special hexadecimal number that uniquely identifies your interface card. If not set, your configuration tool will generate a random number for it, but knowing what it will be ahead of time can help you configure DHCP or a PXE boot. With -virt-install you can set it with the --mac option. VMware’s VI Client provides an option as well.

There are some restrictions. The first three sets of numbers in a MAC address identify the vendor. When setting them, use the following vendor addresses:

Xen

00:16:3e

KVM/Qemu

54:52:00

VMware

12:50:56 AM
