[Xen-devel] Re: DomU LDT emtpy

[david <david_n@xxxxxx>]

Ok, i think I know what the problem is: LDT is 0 :) (winxp sp2). I have
no idea why, but windbg shows me that there is just a 0 stored.

... how can the OS know the details about the segments of the running
process? .. but I think is is the wrong mailinglist for such a question.

cya,
david
