Hi Antonin,

The linux being 'paravirtualized' means that the Linux kernel is  
modified to run on top of L4, so this is not the same as running a  
virtual machine that pretend to be bare hardware. Therefore this  
doesn't involve the VT instructions.

The specialized paravirtualization code of OK Linux is in linux/ 
kernel-2.6.11-v2/arch/l4
