...dlocks with the blktap2 user control plane until the IPC channel is terminated by the timeout on the select() call. This results in a noticeable delay in the termination of the guest and causes the blktap minor number which had been allocated to be orphaned.

Hi all I''m trying to enable VGA passthrough in linux domU without success. I want to pass through AMD Radeon HD 4850 - 03:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV770 [Radeon HD 4850] as a _primary_ VGA for the VM. Nothing is showing up on the monitor that I have connected to graphics card''s HDMI port. I have IOMMU enabled. I searched mailing lists

...was never designed to do. That being said using VM''s for this type of testing certainly makes sense and the behavior is unexpected. Let us know if there are any questions or if additional testing is needed. Have a good remainder of the week. Greg As always, Dr. G.W.

Hi, everyone! I am working on xen-4.2.0 with spice remote connect. My host is Fedora 14 and guest is win7. I have installed spice package and now I can connect to guest by spice client. For better graphics experience, I want to try the VGA passthrough. With spice tool, I have to create a VM by xl command, and now I am wondering if it supports VGA passghrouth? If so, how should I test it ?

...definitely linked to xl since a block device can be initialized and released with the tap-ctl utility with no problems. Let me know if anyone has run into this or a solution. We will keep digging and report back if we isolate the problem. Have a good week. As always, Dr. G.W.

I''m using Xen 4.3, installed from source on Ubuntu 13.04. I''ve successfully installed a Windows 8 guest, and had Xen pass it an AMD FirePro W7000 GPU (technically 2 PCI devices - the second is for the sound), as well as the virtualised graphics adapter. Windows finds the card fine, and I''ve installed AMD''s drivers. Device Manager says that the card cannot

Hello, I am about to try the AMD patch to test primary passthrough and had a couple of questions. First, is there a host for the patch or is it only what was released to the mailing list in the past? Second, does the primary patch allow Xen''s VNC to connect to the GPU instead of emulated graphics? If not, does anyone know whether it would be possible to connect Xen''s VNC to

Gordan & David, Read about your latest work, and was thrilled to learn that both soft and hard mods are working. I bought the GTX 670 model in David''s article, I will be giving this a shot in a week. I was hoping to ask a few questions. 1. Is there a specific qemu version required (traditional or the new default)? 2. What (if anything) should be done after removing the resistors

Hi,all I have tried to passthrough GPU card(Nvidia quadro 4000) on the latest Xen unstable version (QEMU is using Qemu-upsteam-unstable, not traditional Qemu). This issue as below: Windows7 64-bit guest will blue screen when GPU passthrough configure 4g memory,blue screen code is 50, and SUSE 11 64-bit guest will always stay at the grub screen. I noticed that it will relocate RAM that
