RE: [Xen-devel] Help: Could anybody know about the Intel' s "LaGrande" technologies? Did the Xen be under development using this stuff?

["Cihula, Joseph" <joseph.cihula@xxxxxxxxx>]

Hi,

There is a patch to the mid Sept. '06 version of Xen that supports LaGrande 
Technology (now called Intel(r) Trusted Execution Technology or Intel(r) TXT).  
You can find it at:  
http://lists.xensource.com/archives/html/xen-devel/2006-09/msg00698.html.

There has been some discussion following the patch as to how best to 
incorporate such technology into Xen and it was decided that it would be best 
as a separate module that launched Xen (rather than integrated into the Xen 
binary as is the case with the above patch).  I will be releasing a new version 
that supports this model shortly.

I've also sent this reply to the xense-devel mailing list, as that list is 
specifically concerned with the security-related aspects of Xen.
