This may be true for windows, but Linux hvm guests really supports 
consoles through serial consoles.
For fully virt (Linux): ---

Edit guest configuration file and add "serial = pty"

Then edit guest grub.conf file and add console=ttyS0 to kernel line  and 
add "co:2345:respawn:/sbin/agetty ttyS0 9600 vt100-nav" to your 
/etc/inittab.
