Either authorize root by running this, as the user logged into X:

xhost +si:localuser:root

or copy the xauth cookie into root's account using something like the
following:

sh -c 'xauth list "${DISPLAY}" | sed -e "s/^/add /" | sudo xauth'

But I suppose a better question is: why are you running qemu as root?
