Dear Xen Users, I am conducting a poll on the number of Xen users running Windows 8.1 HVM domU and whether it is unstable with Xen VGA Passthrough. Please read the background information at the following xen-devel mailing list thread: http://lists.xen.org/archives/html/xen-devel/2014-09/msg01916.html If your Windows 8.1 HVM domU is stable with Xen VGA Passthrough, please provide me with the following information. My own setup is shown in brackets below. 1) dom0 operating system: (Ubuntu 14.04 LTS) 2) Linux kernel in dom0: (3.16.1) 3) Xen hypervisor version: (4.4.1) 4) Processor: (Intel Core i5 4430 @ 3.0 GHz) 5) Motherboard: (Asrock B85M Pro4 LGA1150) 6) VGA card for VGA Passthrough: (Sapphire AMD Radeon HD 6450 1 GB DDR3) 7) Memory: (32 GB DDR3-1600) I would like to have your Windows 8.1 HVM domU configuration file as well. My own Windows 8.1 HVM domU configuration can be found at http://wiki.xen.org/mediawiki/images/5/57/Xen_VGA_Passthrough_with_AMD_Display_Cards_-_Version_1.4.pdf I am also running Windows 7 Ultimate HVM domU with Xen VGA Passthrough and it is very stable and not giving me any problems. Thank you very much. -- Yours sincerely, Teo En Ming Singapore
