Dear all, Please help me passthrough my GPU the a KVM guest.
The system I am using: lshw: https://pastebin.com/tB7FqqxN Host OS:Debian 9 Stretch Mainboard: Supermicro C7Z170-M (activated VT-d in Bios) CPU: Intel Core i7-7700K CPU @ 4.20GHz GPU: EVGA GeForce GTX1080 Ti The GPU is not listed because I have blacklisted it: $ cat /etc/modprobe.d/blacklist.conf blacklist nouveau lspci: https://pastebin.com/6qYuJRPg I found this guide: https://scottlinux.com/2016/08/28/gpu-passthrough-with-kvm-and-debian-linux/ After installing Win7 guest, enabling PCI passthrough using virt-manager, installing the NVidia driver in the guest, Windows reports the error 43 for the GPU. Windows has stopped this device because it has reported problems. (Code 43) This is described in the above mentioned post and a workaround is linked: https://www.reddit.com/r/VFIO/comments/479xnx/guests_with_nvidia_gpus_can_enable_hyperv/ Unfortunately I do not know how to apply the workaround. I understand that I should create a file '/usr/libexec/qemu-kvm-hv-vendor' with the following content: #!/bin/sh exec /usr/bin/qemu-kvm \ `echo "\$@" | sed 's|hv_time|hv_time,hv_vendor_id=whatever|g'` Or according to the original redhat mailing list post by Alex Williamson: https://www.redhat.com/archives/vfio-users/2016-March/msg00092.html $ cat /usr/libexec/qemu-kvm-hv-vendor #!/bin/sh exec /usr/bin/qemu-kvm \ `echo "\$@" | sed 's|hv_time|hv_time,hv_vendor_id=KeenlyKVM|g'` But since there is no qemu-kvm present and the directory '/usr/libexec' does not exist on my system, I wonder how I should proceed. Any help fixing my problem would be highly appreciated. Thanky you very much in advance and best regards, Ramon
