The boot parameters changed. I think you should have a look at http://xenbits.xensource.com/linux-2.6.18-xen.hg?rev=reassign_resources -- Dexuan -----Original Message----- From: xen-devel-bounces@xxxxxxxxxxxxxxxxxxx [mailto:xen-devel-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of Sander Eikelenboom Sent: 2009?7?21? 20:17 To: xen-devel@ Subject: [Xen-devel] [xen 3.5-unstable] passthrough of pci USB card fails Hi, I'm trying to passthrough a pci USB card to a DomU (HVM). Although pciback seems to seize the device with all functions as seen in the dmesg output, they don't appear using "xm pci-list-assignable-devices". When trying to passthrough to a HVM (with VT-D enabled) it stops creating the domain and complains about: VmError: pci: 0000:01:00.2: non-page-aligned MMIO BAR found. >From what I read, booting the xen hypervisor with "reassigndev=" should solve the non-page-aligned issues, but apparently it doesn't in this case. Also added them to xend-pci-persmissive. Is there another boot-option/way to reassign the device ? Regards, Sander Attached is the output from: xm info xm dmesg dmesg lspci -vvvnnk ls /sys/bus/pci/drivers/pciback /var/log/xen/xend log with the start of a HVM domain winhvm.cfg (config file of the hvm domain) _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
