similar to: Can't get PCI passthrough working

Hello, I've started seeing the following warning in 3.11-rc2. [In the interest of full disclosure, I do have a patch applied that tries to implement drm_planes, which I might have done completely incorrectly, but looking around it doesn't seem related. I'm definitely not invoking any of the planes functionality right now. See http://paste.debian.net/hidden/cf8b3a2, plus a call to the

Hello. I've been tesing VGA passthrough using libvirt. However, My *Windows7*(64bit) Virtual Machine stopped at loading screen as soon as I installed graphic driver(*AMD Radeon HD 7750*) and then restarted the VM. How Can I use VGA passthrough technology in my *Windows7* VM? I attached my testing information(HW, system environment and settings, qemu log and so on..) Best Regards.

Hey Mike, did you ever have any success figuring out this issue? I am having the same problem (on CentOS 7) with a custom data acquisition PCI card. It seems like the solution might have something to do with delaying the start of libvirtd in systemd until the PCI card (or vfio?) is ready, but I don’t know how to do that. Can anyone else offer assistance? My output: 2016-03-29T18:29:26.191010Z

Hello, I have been struggling as of late to successfully configure a pci passthrough using libvirt with kvm. Hoping someone can shed some light on the problem. Overall my experience with virtualization limited is so please forgive. The guest runs fine till passthrough is configured. I am using virt-manager. This has been tried on both a Fedora17 x86_64 and Arch Linux x86_64 build with pretty much

Hi, All I want to use the SR-IOV of intel 82576 NIC. I enabled IOMMU and VT-d and SR-IOV in BIOS. And enabled VT-d in kernel. The OS information is bellow: [root@host3 nova]# cat /etc/redhat-release CentOS Linux release 7.1.1503 (Core) [root@host3 nova]# uname -an Linux host3.localdomain 3.10.0-229.el7.x86_64 #1 SMP Fri Mar 6 11:36:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux [root@host3 nova]#

I'm attempting PCI-passthrough from host to guest on an HP ProLiant 380P, which has an outdated BIOS (2014), but it does support VT-d. I'm running CentOS 7, kernel 3.10.0-862.9.1.el7.x86_64. I have an Intel 82580 NIC installed with 4 ports. Each of these ports is in its own IOMMU group (I enabled SR-IOV at the BIOS, which might be the reason they show up separately) After detaching and

We are using an Intel 82599 chip that allows 4 PFs ( eth0..3) per VM. I am able to manually start VMs using the hostdev definition for the four network connections, but I'd like to start using the pool approach.

When enabling both VFIO and VIRTIO_IOMMU modules, automatically select VFIO_IOMMU_TYPE1 as well.
