Hi Marc-André,

Following this patch, we are not able anymore to launch QEMU with
-monitor /dev/null.
> qemu-system-i386: -monitor /dev/null: 'tty' is not a valid char driver name

FYI, the full command line used:
/usr/lib/xen/bin/qemu-system-i386 -xen-domid 0 \
    -xen-attach -name dom0 -nographic -M xenpv -daemonize \
    -monitor /dev/null -serial /dev/null -parallel /dev/null \
    -nodefaults -no-user-config \
    -pidfile /var/run/xen/qemu-dom0.pid

Regards,
