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

Thanks Ján! >What were the exact changes you were trying to make? I was following this guide: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF#Passing_keyboard/mouse_via_Evdev Specifically, I was updating the domain tag to include `xmlns:qemu=' http://libvirt.org/schemas/domain/qemu/1.0'` >both call virDomainDefineXMLFlags under the hood. That is good to know, thanks for the explanation. I appreciate the help, if you have a...

Do you know any way that I could spy on Windows' accesses to the PCI bridge registers? Looking at at https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF I suspect VFIO would not help me here. It says: Note: If they are grouped with other devices in this manner, pci root ports and bridges should neither be bound to vfio at boot, nor be added to the VM. Thanks Daniel

...sking this question in the right place, so please redirect me if there's a better list. I recently set up a Windows 10 guest on an Arch Linux host with libvirt and KVM/Qemu, using IOMMU to enable GPU passthrough. I followed this guide to set up the VM: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF The problem that I'm having is that the guest is very flaky: sometimes the guest will just hang indefinitely, and sometimes the guest loses network connectivity. Usually when either of these behaviors happens, restarting the libvirtd daemon on the host resolves the issue, but that's n...

...ork. Passing the whole GPU to guest is a little bit tricky and requires several steps. Main reason why it's not automated yet is that each HW combination is specific and requires different tuning. I would recommend you to read this wiki page [1]. [1] <https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF> I was able to configure it on my computer, basically you need to make sure that you have IOMMU available and enabled, that your GPU card is in it's own isolated IOMMU group, configure kernel to assign vfio-pci driver while booting and properly configure guest XML in libvirt. Everything is...

...nabled via Device > Manager, I see writes on the enable path: > > 2571 at 1535108904.593107:rp_write_config (ioh3420, @0x28, 0x0, len=0x4) Did you do anything special to get an emulated bridge included in this setup? Folllowing the instructions at https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF I can successfully pass through devices to windows running under virt-manager. In the nvidia GPU case I haven't got passed the driver installation failure, but I can pass through other devices OK and install their drivers. However I do not end up with any PCI-to-PCI bridges in this setup. The...

This may be user error, I am new to libvirt. I am using libvirt 5.0.0. I have created a VM (win10) in the system URI using virt-manager. I stopped the VM to edit it. I set my LIBVIRT_DEFAULT_URI="qemu:///system" and am able to read the domain configuration with `EDITOR=nano virsh edit win10`. When I save (ctrl+o) and exit (ctrl+x) I see the message "Domain win10 XML configuration

Only non-bridge devices can be passed to a guest, but perhaps loggin...

Hi, We are facing a suspend/resume problem with many different Asus laptop models (30+ products) with Intel chipsets (multiple generations) and nvidia GPUs (several different ones). Reproducers include: 1. Boot 2. Suspend/resume 3. Load nouveau driver 4. Start X 5. Observe slow X startup and many many errors in logs (primarily nouveau fifo faults) or 1. Boot 2. Load nouveau driver 3. Start X
