It's paravirtualization, rather than full virtualization: the Linux kernel is
modified to run in the CoLinux environment. They therefore don't have to do
the tricky bits from full virtualization of catching and emulating privileged
operations.
That said, the code for taking over the IDT, etc. in order to get control of
the system from Windows may be relevant.
CoLinux kernel modules exist for both Linux and Windows IIRC.
