## SYNOPSIS
`randmac` [<options>]
## DESCRIPTION
`randmac` prints a random MAC address. This utility has been designed to
give random MAC addresses to interfaces of virtual machines.
## OPTIONS
* `-l`, `--local`:
Generate a local administered MAC.
* `-g`, `--global`:
Generate a global unique MAC.
* `-u`, `--unicast`:
Generate a MAC for unicast.
* `-m`, `--multicast`:
Generate a MAC for multicast.
* `-U`, `--uppercase`:
Print uppercase hex digits.
* `-e`, `--eui64`:
Generate an EUI64 address.
* `-o` <oui_addr>, `--oui` <oui_addr>:
Set the Organizationally Unique Identifier (OUI).
* `-v` <vendor>, `--vendor` <vendor>:
Set the OUI of a specific vendor.
* `-q`, `--qemu`:
Set the standard OUI of qemu/kvm.
* `-x`, `--xen`:
Set the standard OUI of xen.
* `-h`, `--help`:
Display a short help message and exit.
## EXAMPLE
Start a kvm VM using a random generated MAC address (while preserving
the standard qemu's OUI)
```sh
$ qemu-system-x86_64 -accel kvm ... \
-device e1000,netdev=vde0,mac=`randmac -q` \
-netdev vde,id=vde0,sock=vde://
```
