Hello Dexuan, From what i read, i should replace both pciback and reassigndev with the new guestdev parameter. And it should accept the same syntax as reassigndev. So i tried to boot my Dom0 with: module /boot/vmlinuz-2.6.18.8-xen root=/dev/sda1 ro log_buf_len=65662 guestdev=01:00.0,01:00.1,01:00.2 It seizes the pci devices, but creating the HVM domU still fails with: Error: pci: 0000:01:00.2: non-page-aligned MMIO BAR found. Any more things I could try ? -- Sander Attachted: xm info xm dmesg dmesg xend.log lspci -vvvknn Wednesday, July 22, 2009, 5:02:13 AM, you wrote: > 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) -- Best regards, Sander mailto:linux@xxxxxxxxxxxxxx Attachment:
