This is from a access check in the if_tap module. If you look at
/usr/src/sys/net/if_tap.c, you will notice that there is a check for the
uid == 0 in the open path. It needs to be commented out.

I haven't tried it.

I haven't tried running QEMU on 4.x

On 4.x you have to use something like...
if (!ioctl(fd, FIOCGDINFO, &disklabel)) {
int cyls = disklabel.d_ncylinders;
int heads = disklabel.d_ntracks;
int sectors = disklabel.d_nsectors;
disksize_in_sectors = cyls * heads * sectors;
}
