Hi chris We find this patch will cause SR-IOV fail. Guest will vf assigned cannot get ip and show " do_IRQ: 0.177 No irq handler for vector (irq -1)" in xm dmesg. Can you take a look at this patch and help to fixed the regression? Thanks :) best regards yang> -----Original Message----- > From: xen-devel-bounces@lists.xensource.com > [mailto:xen-devel-bounces@lists.xensource.com] On Behalf Of Christoph Egger > Sent: Thursday, August 05, 2010 11:05 PM > To: xen-devel@lists.xensource.com > Subject: [Xen-devel] [PATCH 13/14] Nested Virtualization: p2m infrastructure > > > Signed-off-by: Christoph Egger <Christoph.Egger@amd.com> > > -- > ---to satisfy European Law for business letters: > Advanced Micro Devices GmbH > Einsteinring 24, 85609 Dornach b.

Re: [Xen-devel] [PATCH 13/14] Nested Virtualization: p2m infrastructure
Hi Yang, we are about trying to reproduce this problem and will keep you up-to-date on our findings. Can you also give us more detailed information, i.e. does this happen with hap only or also with shadow paging ? The changeset http://xenbits.xensource.com/staging/xen-unstable.hg/rev/e7afe98afd43 touches generic p2m code. The EPT code definitely needs an update in respect to get EPT-on-EPT with nested virtualization. Until further analysis is done, I can not say, there is no bug in the p2m changes and I can say as well that you might need Eddies EPT update patch as this may contain the fix you need.
