Hello,my system info: virsh verison Compiled against library: libvirt 3.9.0 Using library: libvirt 3.9.0 Using API: QEMU 3.9.0 Running hypervisor: QEMU 2.10.90 And i want to pass through my gpu to my window 7 guest with <hostdev>, next line is comand i use: <hostdev mode='subsystem' type='pci' managed='yes' xvga='yes'>

Yes, I can use guest with this way, But when i hot-add my graphics card , Guest will reboot. So i want to try it with <hostdev>. Somehow , If i use "hostdev" without xvga , my screen will be black. If we have no hostdev, do you have other methods can help me to use hot-plug my graphics card? At 2018-01-04 23:27:52, "Laine Stump" <laine@redhat.com> wrote:

hi everybody I'd presume virsh makes the best possible choice, right? It is that just seems bit... odd having realtek in guest and Intel's VF on host, no? regards

Hi, I have a guest enabled vIOMMU, but on the guest there are several devices in the same iommu group. Could someone help to check if I missed something?

hi everybody a windows kvm guest would not start, process gets killed with: Out of memory: Kill process 21984 (qemu-kvm) score 44 or sacrifice child I really don't know where/what I might be missing, config seems fine, everything looks ok - I only am not sure, do I need to first stub a SR-IOV device like regular passthrough?

Hello, We encountered a problem while testing SRIOV on kubevirt [1]: We are currently using the Device "hostdev" generic options to pass-through the VF to the guest. It is not done through the "interface" (with type hostdev) because that option requires access to the PF which is not available in our case (the VF is moved to the container namespace where libvirt runs, but not

Hi Cole & Michal, I'm sorry for my late response, I just end my journey today. Thank your response, your suggestion is very helpful to me. I have added Michal in this mail, Michal helps me review my initial patchset. (https://www.spinics.net/linux/fedora/libvir/msg191339.html) All concern about this feature is the XML design. My original XML design exposes more details of Qemu.

Hi all, I'm testing on debian/unstable SR-IOV feature with Broadcom BCM57810 cards and KVM hypervisor: Compiled against library: libvirt 1.2.1 Using library: libvirt 1.2.1 Using API: QEMU 1.2.1 Running hypervisor: QEMU 1.7.0 bnx2x -> firmware 7.8.17 -> driver from kernel 3.12.7 8 VFs are created on the first PF. For each VF, a specific mac address is set manually using "ip

So I have an entry for a USB device ( ID 051d:0002, UPS) I want to use with a given vm client. In that vm client's config file I added something like this: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x051d'/> <product id='0x0002'/> </source> </hostdev>

Hi, I've been using libvirt (versions 0.9.11.5, and recently upgraded to 0.10.2), and have been attaching an SR-IOV VF to my VM with the following device configuration: <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x07' slot='0x10' function='0x0'/>

If I'm using the SR-IOV Pool assignment method (from http://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition ), how would I check how many virtual functions are already in use? Is there a method other then looping through all the active guests and determining if they're using the SR-IOV interface?

Greetings all, I have a host machine that runs a router within a vm. I want to allow a connection between the host and the guest so the host can connect to the lan provided by the router vm. I've created a dummy interface with these commands: $ ip link add ens99-dummy type dummy $ ip link set ens99-dummy address 52:54:00:1f:d0:ff this resulted with this output: $ ifconfig ens99-dummy

Hello, I'm trying to migrate a working qemu command line configuration to libvirt. The part I'm currently failing on is: $ qemu-system-x86_64 -M Q35 ... -device vfio-pci,host=05:00.0,bus=pcie.0 The right way to translate this into libvirt XML seems to be using <hostdev>, but I seem to be unable to plug it into the pcie-root port This is how the interesting part looks like when

Dear List , We are using intel 82599EB based SRIOV capable 10GbE cards on the host machine.The VFs are being assigned to the guest in pass through mode and are providing the network connectivity as expected. However when we shutdown the guest the connectivity does not comes back via the VFs on the guest in next boot unless the VFs are detached from the *guest* *before* initiating a shutdown of

hi laine, thx for the fast answer. i tried VFIO as it seems supported and got at least one step further. starting the guest with one of the DVB cards is possible now, even when the other card is in the hosts pci config (not removed soft or hard). adding the second card/device thru ... > <hostdev mode='subsystem' type='pci' managed='yes'> >
