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. Ubuntu 12.04 libvirt 1.0.0 Following: http://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition I can get a pool working with

Hi, I try to add 2 VF functions to VM via network. Livirt networks: vnet0: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf dev='eth0'/> </forward> </network> vnet1: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf

I'm looking for assistance with pci-passthrough on CentOS 6.2. I've installed libvirt version: 0.9.4, package: 23.el6_2.8 from yum. I have a windows XP client setup via virt-manager which boots and runs fine until I attempt to assign a PCI device to it. The error log reads: -----------------/var/log/libvirt/qemu/SageTv.log---------------- 2012-06-02 22:55:07.801: starting up LC_ALL=C

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

Hi, This is regarding SRIOV in Rhel7. I have added intel_iommu=on in grub.cfg file. When I attach Virtual Function to VM and I try to poweron the VM, I get the below error: [root@Dell-Rhel7 ~]# virsh start rhel64x64GA error: Failed to start domain rhel64x64GA error: internal error: early end of file from monitor: possible problem: qemu-kvm: -device

I can see from different post that if working with sr-iov, i should work with vlan Is this an obligation to work with vlan if working with sr-iov? If not according to which parameter will the different vf get the traffic. Let's say i declare max_vfs=7, how will the traffic be seperated between the vm? However till i get an answer i tried to work with vlan And i still don't get

I'm trying to get PCI passthrough working by passing through a DVB-T TV card to a VM running MythTV. When I assign the PCI devices in virt-manager and attempt to start the VM I get this error: Error starting domain: internal error: process exited while connecting to monitor: 2015-09-06T12:41:09.725990Z qemu-kvm: -device vfio-pci,host=05:02.0,id=hostdev0,bus=pci.0,addr=0x9: vfio: error, group

Hey all, I'm getting an error starting a libvirt managed qemu/kvm VM at physical host boot time, but manually starting it afterwards works fine. This is on a Ubuntu Wily i7-4790 box running Linux 4.2 and libvirt 1.2.16. There is a legacy (5V) PCI card being passed through to the VM, the error seems to relate to that. The error that always appears at boot in

I have an Intel X540 SR-IOV NIC in a box with ACS support running RHEL6.4. Hi Hongming, I'm hoping you can please help with two issues: 1. The pool works, but I transparent VLAN with the pool does not. I have to manually run "ip" afterwards to get it to work. # virsh net-dumpxml em2net <network connections='1'> <name>em2net</name>

I would really appreciate some pointers on what I am doing wrong here. I have a need to run multiple virtual guests which have each their own GPU and some USB controllers passed-through. I am able to run one of the guests like this (assuming vfio stuff has happened elsewhere), but I would prefer to use virsh: kvm -M q35 -m 8192 -cpu host,kvm=off \ -smp 4,sockets=1,cores=4,threads=1 \ -bios
