FYI. I saw the same issue on x38 & x48 chipset. Wondering if we can manually modify the DMAR table. Thanks, Neo --------- I would remember that if researchers were not ambitious probably today we haven't the technology we are using!On Nov 25, 2008, at 2:45 AM, Keir Fraser <keir.fraser@xxxxxxxxxxxxx> wrote: On 25/11/08 10:10, "Ralf Hornik Mailings" <ralf@xxxxxxxxxxxxxxxxx> wrote:Now, after recompiling xen version 3.3 (make dist) I get the followingerror in "xm dmesg": ...

However, the table relates to Intel's VT-d feature which you are almost certainly notusing. -- Keir _______________________________________________ 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
