Hi, I successfully passed my VGA to my domU. mobo: GA-990FXA-UD5 vga: Gigabyte HD 6850 dom0: Debian testing kernel: 3.4.12 xen: 4.2 release domU: fully patched Windows 7 I didn''t need to tweak anything, "it just werks" out of the box. I followed this guide: http://wiki.xen.org/wiki/Comprehensive_Xen_Debian_Wheezy_PCI_Passthrough_Tutorial The tutorial is simply awesome, well written and understandable. However, I can''t get some of the GPLPV drivers working really well. What I can''t get to work is the net and the vbd driver. Windows sees the net driver as OK, but accessing webpages is impossible. If you know the exact address to a .exe file or something and you copy the link into the address bar it downloads it as anybody expect it to do, but if I click on the "customize Firefox" link, it hangs at the "connecting to mozilla.org" message. The vbd driver is working fine, my experience index went up 1,2 points after install, but one of the three "xen block device" or something like that in device manager has a yellow exclamation mark next to it, which bothers me. Is it normal? Can somebody give me any tips what to do? I''ve tried the 0.11.0.369 and the 0.11.0.357 versions, I''ve added "type=vif" to my config file. I used the "full install" option. Misi

Re: VGA passtrough success report, GPLPV driver question
Hello Misi, Congratulations on your successful passthrough. I am still using the .357 drivers so I can''t speak with regards to the newer version. ---- Starting with your device manager observation, if that device is something like "Xen pci device #0", then yes it is normal. My understanding is that it''s used by Xen and does not have an associated Windows driver. --- As for the network problems, I haven''t encountered anything quite like that, but I can throw out some suggestions. First, is this only happening in FireFox, or also IE/Chrome? Second, do you have anything besides a router/switch between your machine and the internet? For example, a proxy or firewall? Finally, can you share your Dom0''s /etc/network/interfaces file, and your windows hvm configuration file? In your HVM Configuration, you should be sure your mac address has the 00:16:3e prefix, so it should be something like this: vif=[ ''bridge=xenbr0,model=e1000,mac=00:16:3e:14:b1:1c'' ] If you use a different mac address, you may encounter strange bugs. The interfaces file should look like this if you have only one ethernet in use: auto lo xenbr0 iface lo inet loopback iface eth0 inet manual iface xenbr0 inet dhcp bridge_ports eth0 In my case I have an IPFire HVM so I am using two ethernet ports and have bridged the connections to place Dom0 and all VM''s behind the firewall. My revised configuration looks like this: auto lo xenbr0 xenbr1 iface lo inet loopback iface eth0 inet manual iface xenbr0 inet manual bridge_ports eth0 iface eth1 inet manual iface xenbr2 inet dhcp bridge_ports eth1 Since you can download files using URL''s it isn''t a DNS issue, but I have run into problems with Dom0 when changing from DHCP to a static configuration, where the /etc/resolv.conf file would retain old DNS Server information and fail to load addresses (but work with IP''s). The only other problem I have had with the GPLPV drivers specifically has been that my network device if disabled cannot be re-enabled, forcing me to reboot the Windows to get the network back online. Obviously failing any of these changes you can always try removing the GPLPV Network Drivers specifically, I do not know if the performance gains are as significant as the VBD drivers, but I haven''t tested it thoroughly. --- Also, I am glad you liked my tutorial, your feedback is appreciated. I will see about adding more information to the GPLPV driver installation segments, and more on the network configuration bugs I have run into. I have plans to add HVM Router configuration instructions, new hardware I have been testing, and various improvements to certain installation/configuration steps. Let me know if there is anything in particular you would like to see added or modified.
