Vanderpool and Xen 3.0 question !

Vanderpool and Xen 3.0 question !

[Charles Collin]

Hi,

The following topic might be a little prematured!

 From what i have understood, next generation CPUs such as Pentium D 
will integer Vanderpool technology also called IVT, and this technology 
should enable Xen 3.x to run MS Windows XP without paravirtualization 
kernel modification, right?

If so, here is my question:
Will Xen 3.x enable (/do xen developpers plan on enableing) users to run 
Windows XP NFSrooted (or some sort of "software streamed" Windows XP 
image on a remote server) ?
I've heard about a "int 13 trick" used by proprietary programs 
redirecting disk accesses over the network. If no Windows-NFSroot is 
natively supported (i mean as described in the documentation), would Xen 
be the right place to implement the int 13 trick for diskless Windows?

BTW, i run my Linux LFS/BLFS 6.0 NFSrooted box under Xen and it works " 
'o good Lord" impressively very great. Great job guys ;-)

I believe that's the plan, although for maximum performance you might 
install special Xen device drivers into the WinXP interface.

I don't know what Windows support for directly talking to a network root 
filesystem is. However, you should be able to present the guest (i.e. 
Windows in this case) with the illusion of an ordinary block device, 
whereas in dom0 it is actually a file on a network share / an ENBD device / 
whatever.

Glad to hear it.

HTH,
