no, that's not it. if it was, the virtual would boot even without displaying
anything and i'd get there throught ssh. I've tried console over serial (this
works with 3.0.3 hypervisor) and console on vga, both get stuck right after
xen hypervisor starts. 

I've tried the exactly same setup on a desktop hardware and it works just
fine.

there must be something wrong with the hardware. if it was only that one
server, i'd forget about it and move to another one, but so far it does this
on every hardware that has intel vt which i need. however, i've tried to 
disable 
that in the bios setup but it didn't help. 

the weird thing is it gets stuck right after grub, without even producing any 
messages and it freezes the hardware solid. even keyboard numlock stops 
responding.
