Pls list the following info: platform, BIOS, dom0 changeset, Xen changeset, did you add-on extra graphics card? did you follow steps listed in docs/misc/vtd.txt? 64BIT Debian stable (etch) Lenovo Thinkcentre M57 - Typ 6075-BQG Bios Version 2RKT54AUS Bios Date 08/20/2008 Dom0 is 2.6.18.8-xen Kernel with Xen 3.4 xen-unstable.hg, plain installation without any modifications at all One HVM guest for testing, windows 2000 with pci = [ ' 01:00.0' ] line in its configuration. I add a pci graphic card for testing purpose to have vga output in case i hide the pci-e card. that pci card is not used for passthrough. I followed steps listed in http://lxr.xensource.com/lxr/source/docs/misc/vtd.txt but came to the conclusion that it might have something to do with Base Address Register? > Actually, latest Xen VT-d is quite stable in our recent testing. I wish here too. Regards -- Stefan
