<p>Robert larsen: Added tip on a (in my opinion) better MAC address generator</p> <hr /> <div>In the section about running kvm as a non-root contains a setup that will not work. It says that one need to create a ''qemu-ifup'' script containing the line:<br /> <br /> /usr/bin/sudo /usr/sbin/tunctl -u `whoami` -t $1<br /> <br /> However, it will not work and result in an error-message when running ''qemu-system-x86_64''. The command above needs to be run before ''qemu-system-x86_64''.<br /> <br /> <br /> <br /> I think this oneliner for generating a random MAC address is much more readable, and as an added bonus it will use the entire 16 bit space:<br /> printf &quot;DE:AD:BE:EF:%02X:%02X\n&quot; $((RANDOM&amp;255)) $((RANDOM&amp;255))</div>
