I am running Xen 4.6 on CentOS 7 in a Dell Poweredge T430 I need PCI Passthrough to get USB working. I am following the Xenproject Wiki I have enabled the Virtulasation in the BIOS. I have xen_pciback as a module I have issued the command: xl pci-assignable-add 00:1a0.0 and it shows up fine when I issue this xl pci-assignable-list I have pci=['00:1a.0'] on the DomU config file I

I''ve just had my first attempt at getting VGA passthrough to work, and it crashed the machine. I''m trying to understand whether this is a problem with my hardware, configuration or a software problem.

Hello, I hope that I am posting the correct list with this question. I have been trying to get VGA passthrough working on my system for some time now without success. I do not have the system with me right now, so I will not be able to provide any logs or error messages right now. I will be able to to do so in a couple of hours.

Add commands to automatically prep devices for pass-through The current method for passing through devices requires users to either modify cryptic Linux boot parameters and reboot, or do a lot of manual reads and writes into sysfs nodes. This set of patches introduces commands to make this easier. It expands on the concept of "assignable" (from the list_assignable_devices command).

Package: xen-utils-common Version: 4.4.1-6 Severity: normal Dear Maintainer, (There appear to be several reports on the BTS with concerns relating to this report. Some unarchiving/merging may be necessary. Reassignment may be needed as well since I'm not sure which package this problem would fall under. Ultimately decided to file with xen-utils-common with 'xl' being the frontend

I have a system with several reserved ranges low in the e820 map which cause problems when starting PV domains with PCI devices. The machine memory map looks like: (XEN) 0000000000000000 - 0000000000060000 (usable) (XEN) 0000000000060000 - 0000000000068000 (reserved) (XEN) 0000000000068000 - 000000000009ac00 (usable) (XEN) 000000000009ac00 - 00000000000a0000 (reserved) (XEN) 00000000000e0000

Currently we assign devices with VT-d in Xend, this raises two issues: 1) assign devices regardless of they are hidden by pciback or not. If the device is not hidden, it results in the device doesn''t work in Dom0; 2) device is assigned one by one, if assign multiple devices, some devices may have been assigned when problem happens, it results in assigned devices don''t work in

Add support for a xenstore dm command to flush qemu''s buffer cache. qemu will just keep mapping pages and not release them, which causes problems for the memory pager (since the page is mapped, it won''t get paged out). When the pager has trouble finding a page to page out, it asks qemu to flush its buffer, which releases all the page mappings. This makes it possible to find

hi all, i just wonder, after searching the online resources, if there is any paper describing howto uninstall completelly xen: - xen, - tools and - stubdom from a debian box. maybe also a brief description how to update, for example, a xem 4.1.2 to 4.2 in a future step? i use: - debian 6.0.5 amd64 - xen 4.1.2 - kernel 3.4.4 thanks a lot for your answers walter.

Hi, everyone. I''m Guilherme Suzuki (brazillian, by the way) and really interested in xen-vga-passthru. Lately, I bought a brand new Saphire HD 7950 (OC Boost) because I saw in a wiki somewhere that users have been able to passthru these VGA devices to domU (win7, win-xp and so on). But, after I installed it, I executed *lspci -vv* to check if FLR in DevCap was present (which
