similar to: Re: PCI Passthrough of 2 identical devices

hi, i have a small trouble with pci-passthrough. i have a working configuration passing a tv card into the guest, all is fine and dandy. as soon as i add my second identical card into the host i cant start the guest anymore, whether i add the second card to the guest or not. error message is identical in both cases. message of virt-manager|virsh|libvirtd.log: > libvirtError: internal error:

Hi, I'm using QEMU/KVM on RHEL (CentOS) 7.8.2003: # cat /etc/redhat-release CentOS Linux release 7.8.2003 I'm passing an NVMe drive into a Linux KVM virtual machine (<type arch='x86_64' machine='pc-i440fx-rhel7.0.0'>hvm</type>) which has the following 'hostdev' entry: <hostdev mode='subsystem' type='pci' managed='yes'>

Let's say I have libvirt [root@vmhost2 ~]# virsh version Compiled against library: libvirt 4.5.0 Using library: libvirt 4.5.0 Using API: QEMU 4.5.0 Running hypervisor: QEMU 2.12.0 [root@vmhost2 ~]# running on centos 8 and then I have this card [root@vmhost2 ~]# virsh nodedev-dumpxml pci_0000_01_00_0 <device> <name>pci_0000_01_00_0</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

Greetings, I have two machines running the same distro, both running qemu 5.1.0, one runs libvirt 6.7.0, the other 6.8.0. I've decided to test the viability of passing through my sata cdrom into a vm, so I went to the libvirt docs, read a bit and added the following to a debian10 uefi vm running on libvirt 6.8.0: <controller type='scsi' index='0'

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

I'm attempting PCI-passthrough from host to guest on an HP ProLiant 380P, which has an outdated BIOS (2014), but it does support VT-d. I'm running CentOS 7, kernel 3.10.0-862.9.1.el7.x86_64.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

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:

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 have Centos 7 (updated) running as my host, and I?m using Qemu and KVM, version 2.0.0 and 2.6.0. I have a Trendnet TU-S9 USB serial dongle attached to the host, which uses the Prolific 2303 chipset. I blacklisted the pl2303 driver so the host doesn?t grab the device, and want to expose it to the guest. On the client, I see 2 USB hubs (3.0 and 2.0), and I see 2 USB endpoints (even though
