Looking at the files I am under the impression that your Dom0 is a pretty recent one, say 2.6.31. There was a missing patch that did not share IRQs in that tree that got added.. on 2010-02-19: commit 733bcb9a1a2d8dba3a4ef3edc3bc009f56251404 Merge: be30a4f 7ec723a Author: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx> Date: Fri Feb 19 14:18:19 2010 -0800 Merge branch 'xen/pcifront' into xen/master * xen/pcifront: xen-pci: Take advantage of the shared IRQ flags. xen/apic: fix shared irq device passthrough I am curious whether you have that or not? If you see that, then you are set on your Dom0 side. Your DomU kernel is a mystery to me. From your [4] it looks as an old PCI front driver, say 2.6.27 or 2.6.18 type. I've looked briefly at fli4l-3.5.0-rev18309 web-site and the kernels I found there had no Xen support. So.. what kernel is this? It is paramount for the Dom0 and DomU to both have the patches for shared IRQ to work properly. At some point the Dom0 code paths had it, but not the DomUs. Nowadays, all of the Jeremy's xen trees should have it: xen/stable-2.6.31.x , xen/stable-2.6.32.x and xen/next. > > > 4). your console log of DomU.
