similar to: Cannot Write xvga=yes in xml file

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! I'm oVirt developer responsible for most of 'hostdev' support. While working on SCSI passthrough (that is hostdev type='scsi'), I've encountered few issues I'm not sure how to solve somewhat effectively and nicely. Just a note - oVirt by default disables 'dynamic_ownership', meaning we have to handle endpoint ownership/labeling ourselves. This is not

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

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.

I'd also like to point out that, when setting up a linux container with _just_ the lxc tools available in ubuntu, all that was needed to be done was whitelist the appropriate cgroups for the Android devices. The lxc tools seem to create the appropriate character devices when you detach/attach the Android device via USB, and the Android `adb` tool recognized the devices. So, a tangential

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

Hello, Everybody. I encounter a problem when i using my guest. I booting my guest without HDMI primarily, Then i add it, but my guest is be rebooted. To know what cause it, i do it again, especially i check my guest is running normal or not with "ping" before plugging, that's well. What i was suffer? can you help me solve it? Following message is detailed!!! Guest: window 7

Can you see the USB device in the lxc? My answering assumes you cannot see the USB device in the container. If you can see it, please ignore my answer. According to my understanding, “hostdev mode='subsystem' “ is used with KVM only. We use this if we want to passthrough a device to a KVM virtual machine. After doing that, the host machine will lose control of the device. If container is

Hi! I ran into a problem using a USB device and was wondering if you could help me. I'm running a Win XP SP3 in a VM with libvirt on a Xubuntu 11.10. I configured it to talk to several USB devices. With one particular device (a Phonak Compilot[1], admittedly a probably rather unusual device), the VM dies with the following error in the libvirtd.log: 2012-07-20 21:04:19.591+0000: 1282:

Dear Daniel, I found that lxc driver doesn't support hostdev with type of 'pci'. As you mentioned before, I tried to expose the device node (the PCIe card) to the container, my XML is as follow: <devices> <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address bus='0x01' slot='0x00'

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 all, I've disabled cgroups v1 on my system with the kernel boot option "systemd.unified_cgroup_hierarchy=1". Since doing so, USB hotplugging fails to work, seemingly due to a permissions problem with BPF. Please note that the technique I'm going to describe worked just fine for hotplugging USB devices to running domains until this change. Attaching / detaching USB devices

Thanks Martin for the info. I have tried the below snippet in the libvirt xml. <hostdev mode='capabilities' type='storage'> <source> <block>/dev/sdc1</block> </source> </hostdev> ------------ root@ir800-lxc:~# mount /dev/sdc1 /mnt/usbdr/ mount: permission denied (are you root?) ---------- It works if the

I'm all Linux at home and trying to get a Win7 running in a VM on CentOS 5.6 and kvm to connect to my iTouch and iPhone. When I plug the iPhone in and run lsusb I get an address of 05AC:12A0 I put that into a hostdev block in the xml file that defines the VM. <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor

I'm using a bit of a different keyboard, the infinity ergodox [ https://input.club/devices/infinity-ergodox/]. It functions just fine as a keyboard on my host computer, but when I try to bind it to the guest, nothing seems to happen. lsusb gives its ID: Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub *Bus 005 Device 003: ID 1c11:b04d* Bus 005 Device 001: ID 1d6b:0002 Linux
