It sounds like you've already got a basic understanding of how vmexits work at a high level? The main vmexit handling code is in xen/arch/x86/hvm/vmx/vmx.c:vmx_vmexit_handler(). It already has code to handle cpuid exits. So you'd just need to add code to the cpuid handling function, possibly enable CPUID vmexits (if they're not enabled already). -George On Thu, Jul 29, 2010 at 9:45 AM, Jonathan White <jonxwhite@xxxxxxxxx> wrote: > Hi, > > I would like to start write some simple Intel-VT VMExit handlers in Xen - > for e.g. when CPUID is executed, or some other VM Exit condition is > satisfied. > How can I define new VMExit conditions for a Intel-VT based HVM guest > (WinXP) in Xen? and how can I write simple handlers for those conditions? > > What is a good place to start in the Xen (or Dom0?) code for the above > requirements? > > Thanks a lot, > Jon > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@xxxxxxxxxxxxxxxxxxx > http://lists.xensource.com/xen-devel > > _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
