Re: [Xen-users] [Xen-devel] Successful Xen VGA Passthrough with Sapphire AMD Radeon HD 6450 Display Card

Dear Gordan Bobic,

I think that in the past, the xend daemon used to create network bridge automatically. But now that xend has been deprecated in Xen 4.4.1, Xen doesn't create network bridge automatically any more.

As I am not very good with networking, please refer me to a detailed guide where I can learn how to create a network bridge for use in Xen 4.4.1.

Thank you very much.

Yours sincerely,

Teo En Ming

AFAIK, there is no automatic bridge creation - you need to do this yourself in whatever way your distro handles it.

By the way, there's another problem. Xen 4.4.1 does not create a network
bridge. The command "sudo brctl show" shows up nothing. Please teach me
how to create a network bridge in Xen 4.4.1.

Thank you very much.

Yours sincerely,

  I would like to report successful Xen VGA Passthrough with Sapphire
  AMD Radeon HD 6450 display card.

  Details are as follows:

  Host operating system dom0: Ubuntu 14.04 LTS
  Linux kernel: self-compiled 3.16.1
  Xen hypervisor: self-compiled 4.4.1
  Guest operating system domU: Windows 7 Ultimate HVM domU
  Sapphire AMD Radeon HD 6450 Driver DVD: INSTALLED

  Please refer to the attached file amd.txt for installation details.
  I will write a more detailed installation guide later on. Stay tuned.

  Also please refer to attached screenshot showing that AMD RADEON HD
  6450 in Display Manager DOES NOT have error code 43. There is NO
  yellow exclamation mark beside the AMD Radeon HD 6450 in Display
  Manager. Xen VGA Passthrough is fully successful.

  I would like to report that Xen VGA Passthrough with Windows 8 HVM
  domU is NOT successful. Although Windows 8 HVM domU can boot up
  successfully initially with successful VGA passthrough, it
  SUBSEQUENTLY keeps rebooting forever whenever I tried to start
  Windows 8 HVM domU.

  Currently I have a problem. Although I passed through the USB
  controllers, the USB keyboard and USB mouse is not working. I need
  to open a VNC Viewer to Windows 7 HVM domU and control the USB mouse
  from within the VNC Viewer. This is not ideal. Please help me with
  this problem so that I can use the USB mouse and USB keyboard
  directly within Windows 7 HVM domU.

  Thank you very much.

  Yours sincerely,

  Teo En Ming
