similar to: USB PCI Passthrough System Instability

Hello, Hope you can help. A while ago users noted performance degradation or dom0 stability issues when shuting down a HVM guest that uses VGA passthrough (e.g. Windows 7), and booting up the guest again. A workaround was to eject the graphics card within Windows, before shutting down the guest. This process is described here: http://blog.ktz.me/?p=219. I tried to follow those instructions, but

I am working on a workstation environment where users can be seamlessly presented different VM''s without having to manually click and move VM windows on top of other windows or Dom0. I was wondering if there were any terminal command sets that can use to achieve this effect. I know there are xen commands to show and hide VM windows, but I would also need to be able to commands VM

Hi, I have used this http://wiki.centos.org/HowTos/Xen/Xen4QuickStart and everything works like a charm then I installed a VM using http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt only to realize later that I don't want NAT. I would want to use PCI passthrough and so i used virsh net-destroy default virsh net-undefine default and net-create /home/kartik/passthrough.xml

Greetings - I saw Andrew Holway's post yesterday referencing using PCI passthrough as a solution to someone else's issue. Not being familiar with it, the post made me look into it more to see if it is something to use for my setup. From my research on the web, I have two questions to make sure I understand how PCI passthrough works. 1. If you use PCI passthrough on a graphics card

Hi everybody! On a Centos 5.8 with libvirt qemu-0.10.5-1.el5.2, libvirt-0.8.2-22.el5 and 2.6.18-308.11.1.el5 I have a Windows machine that used to have pci-passthrough for a device enabled and working. After an update (kernel, libvirt afaik) and a reboot, pci-passthrough stopped working. Intel IOMMU is enabled (can see that from the dmesg output). All i get on the console when i try to start

I hope someone can enlighten me. I have a quad-port Intel 82580 nic (igb driver) on my system and I''d like to dedicate each nic to a HVM via VT-d PCI passthrough. The IOMMU on my system seems to work, I can assign the PCI devices to my HVMs. The HVMs see the pci device and load their respective igb drivers, and ethtool -i eth0 works on each HVM, shows the drivers are loaded and the

Is there any information available when one can expect OpenSolaris to handle PCI Passthrough als Dom0? This thread: http://opensolaris.org/jive/thread.jspa?threadID=45875&tstart=135 makes me think there might be some work going on... Thanks Ares

Hi Jeff. I read that you use PCI Passthrough and works well, i was wonder if you can tell me how you do that ''cause i can''t find how to do it :( and i really need to. So if you can give some advice about how you do it would be really helpful. I appreciate your help Jeff.

Hi: I am trying to understand the current pass-through device in Xen. To my understanding, Xen can hide a PCI device from Dom 0 and exclusively assign it to a guest OS (dom U), right? Does Xen support to assign one device to multiple guest OSes? Does current pass through require Intel -VT or AMD SVM? Where is the source file for the pass-through function? Is it in xen/drivers/passthrough? BTW:

Hi, Is anybody using pci passthrough with unstable 3.4? I have set mode to passthrough in the kernel config and assigned a network card to a windows hvm, the device is detected as "Xen Pci Device #0" but when I look at the device properties they do not match the card and I the driver does not load. Is passthrough broken? Andy _______________________________________________ Xen-users

hello at the moment i have several esxi virtual-server with a unsufficient and slow storage-concept included (or i have to pay a lot of money). so i use separate zfs server (free nexenta + my napp-it web gui) as a nas/san server to store virtual machines on nfs shares. this two server concept is fine for our primary server but not for cost sensitive systems like test installations, home

Hi list, The crux of my setup is given in the Subject: field. I''m using Xen 3.0.3 (release) on a VIA Nehemiah chipset with Linux 2.6.16.29 in both dom0 and domU. Because the documentation on PCI passthrough is a bit sparse, I''m turning to the mailing list.. hopefully you guys have some input. My goal is to set up a system where: * 1 domU VM runs at a time. * The VM can be

I''m wondering if FLR really must be supported by the PCI card for PCI/VGA passthrough to work or if it will work anyway. I have read in the VTdHowTo that trying to pass through hardware without the FLR feature will result in an error. At the same time I read on a pdf document on the VMWare website (http://www.vmware.com/files/pdf/techpaper/vsp_4_vmdirectpath_host.pdf) that:

Hi, I saw there was an active discussion about pci passthrough support in KVM. I'm not a Dev, only a sys admin that need this support. As i saw on the KVM home page that this feature is plan for 2H2008 in the roadmap, I wondered if you already have a more precise time frame for this release? Xen already have this feature but for the rest i prfer KVM. As this is a key point for the final

Greetings, I have Xen installation with all domains (dom0+domU) being Debian Lenny. I''d like to pass my usb printer to one of those domU domains. I couldn''t make usb passthrough to work, so I decided that I will pass the whole usb controller to the domU. It didn''t worked either. I have read tons of internet howtos only to find the solutions proposed don''t

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, I am currently considering to upgrade my Ubuntu Hardy Dom0 from Xen 3.2 to 3.3, but I am a bit concerned about some of my DomUs that rely on PCI Passthrough. Are there any restrictions or problems with PCI Passthrough in Xen 3.3, anything I have to look out for, especially with the Hardy Dom0 kernel in mind? Thanks, Paul. -

Hello, I''m trying to reverse-engineer a PCI sound card driver. The card is assigned to a Xen HVM guest (Windows) using PCI passthrough, the driver is installed and works. I had to compile Xen 4.2.3 from source as PCI passthrough is broken in 4.1.4-3+deb7u1 present in Debian Wheezy. Now I need to capture/log/dump/trace PIO and/or MMIO accesses that the driver does to the assigned
