Could you send me the lspci -vvv output of both devices? That is the one working and non-working. Also is there anything in the QEMU log? One of the items that has not yet been back-ported from 2.6.18 is making the BARs page-aligned... and I wonder if that is what you are hitting (thought the more I think about it the less I think it is that - the xm code will give you a fat warning about this). _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
