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:
/usr/bin/sudo /usr/sbin/tunctl -u `whoami` -t $1
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.
