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

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?

Hi, I'm using libvirt and qemu on Debian Wheezy. I'm having a strange behavior. Guests can't connect to each other when they're on the same host. On the host I'm using bonding (in active / backup mode) and vlan. It looks like this : eth0 \ / macvtap0 bond0 --- vlan222 eth1 / \ macvtap1 So I've got two guests, let's say A and B. When

Hi Ashish, I have tested with your xml in the first mail, and it works for rx_queue_size(see below). multiqueue need to work with vhost backend driver. And when you set "queues=1" it will ignored. Please check your qemu-kvm-rhev package, should be newer than qemu-kvm-rhev-2.9.0-16.el7_4.2 And the logs? tx_queue_size='512' will not work in the guest with direct type interface,

Greetings, I have a vm on debian 9.5 to which I pass an specific usb from the host. here is the relevant part in the vm's xml file: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x148f'/> <product id='0x5572'/> </source> <address type='usb'

The guest was setup through virt-manager. The machine is not configured much after a F20 install (I believe I didn't change any network things) Here is the network part: <interface type='direct'> <mac address='52:54:00:fe:b0:66'/> <source dev='em1' mode='bridge'/> <target dev='macvtap0'/> <model

Greetings, I was wondering what is the proper way to configure a scsi cdrom pass-through so in when the qemu line is generated, host_Cdrom will be used instead of host_device. looking at https://gitlab.com/libvirt/libvirt/-/blob/master/src/qemu/qemu_block.c#L1090, I see that hostcdrom must be true. in order for that to be true, the following must be (see

I have a host setup for libvirt kvm/qemu vms. And I wonder a bit about the overhead of the macvtap and how to configure the mtu's properly. To be able to communicate with the host, I have moved the ip address of the host from the adapter to a macvtap to allow host communication. I have the below setup on hosts.

Greetings, I'm executing an external script when the qemu hook is called with start or release, the script is rather simple, upon start it iterates over the output of lsusb -t and for each device, it looks if it should be added to the vm we started, if so, it attaches it to the vm as follows: virsh --connect qemu:///system "${cmd}" "${domain}" /dev/stdin << END

Hello @ all With the rebuilding of my Server from Debian 9 to Debian 10, I also switch from Virtual Box to Libvirt/KVM. Due to new requirements for the VMs, now I have an actual problem, which unfortunately I can not solve. The problem has already been discussed in the German Debian-Forum ... unfortunately also without success. The facts: - ISP = Dual Stack with daily separation - Host and

I am running Fedora 16 64bit and installed libvirt. I have the VM running with arm emulation with this one issue I can't figure out. I used Virtual Machine Manager to manage the VM and can access its console there. The Ethernet appears to be eth1 and the guest can set an IP on it etc. However, I cannot see any traffic from the Host when dumping any of the interfaces. I've tried

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'>

OK, I have a strange problem. It is probably something simple/stupid, but I cannot figure it out. I have a nice new PowerEdge T20 that I installed CentOS 6 (6.5) on with Virtualization (KVM). I then installed Ubuntu 14.04 in a virtual machine, with a bridged network: ------ begin ub140464.xml------------------ <domain type='kvm' id='2'>

I know these are mostly gamers but they have a lot of experience doing PCI pass though: https://discord.gg/du9ecG I have found them extremely helpful in the past doing libvirt PCI passthough. *Paul O'Rorke* On 2020-02-05 10:13 a.m., Jim Fehlig wrote: > On 2/4/20 1:04 AM, Christoph wrote: >> this config does not work... why? > > Without more details, I don't know why
