Hello, this is the first time I write the list. I encounter a problem I am desperate. I want to launch a Windows VM with 3D. Without the passthrough, I do not worry MEETS. Now with the launch passthrough, I have the following message: Using config file "./Windows7.hvm". Error: pci: PCI Backend and pci-stub don''t own device 0000:01:00.0 At the core virtual PCI Passthrough course. Here is the config grub title Xen 4.1.0 root (hd0,4) kernel /boot/xen.gz module /boot/kernel-2.6.34-xen-r4 root=/dev/ram0 real_root=/dev/mapper/isw_dcgdjhjbdg_Raid55 dodmraid dolvm domodules ro nomodeset pci=resource_alignment=01:00.0 xen-pciback.hide=(01:00.0) module /boot/initramfs-2.6.34-xen-r4 Following option in the VM under /etc/xen/ gfx_passthrough=1 pci=[''01:00.0''] How can I debug the problem. Thank you in advance for your advice, I am lost. Sincerely, Spy20 P.S : I''m French and I don''t speak English fluently <javascript:void(0);> _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
