Ok, I've been working with this for a couple hours but this command line 
errors on F10 like this:

# /usr/bin/qemu-kvm -S -M pc -m 512 -smp 2 -name MX_3 -monitor pty -boot 
d -drive 
file=/var/vm/vm1/qemu/images/MX_3/MX_3.img,if=ide,index=0,boot=on -cdrom 
/dev/sr0 -net nic,macaddr=00:0c:29:e3:bc:ee,vlan=0 -net 
tap,fd=17,script=,vlan=0,ifname=vnet1 -serial none -parallel none -usb 
-vnc 127.0.0.1:1 -k en-us
TUNGETIFF ioctl() failed: Bad file descriptor
char device redirected to /dev/pts/2

What does this error mean?
