Hi,
I'm trying to passthrough gpu card to windows 7 guest, but I got the error code 43. I use ovirt node: ovirt-node-ng-installer-ovirt-4.1-2017032304.iso and ovirt-engine-appliance-4.1-20170322.1.el7.centos.noarch.rpm I have added options "intel_iommu=on rdblacklist=nouveau pci-stub.ids=10de:1380,10de:0fbc" to the grub.conf and attached these devices to the guest. After I have installed the gpu's driver, I got the error code 43. Did I miss something? Any pointers or suggestions would be greatly appreciated.
You are most likely using consumer grade GPU that errors out in Windows if it's running under virtualized environment. You could try using the following hook (make sure it's in /usr/libexec/vdsm/hooks/before_vm_start and it's executable bit is set (chmod +x ...)). Just copy paste the following block to a bash and try to start the VM again. cd /usr/libexec/vdsm/hooks/before_vm_start cat << EOF >> 99_mask_kvm #!/usr/bin/python2 import hooking domxml = hooking.read_domxml() hyperv = domxml.getElementsByTagName('hyperv')[0] smm = domxml.createElement('vendor_id') smm.setAttribute('state', 'on') smm.setAttribute('value', 'whatever') hyperv.appendChild(smm) features = domxml.getElementsByTagName('features')[0] kvm = domxml.createElement('kvm') hidden = domxml.createElement('hidden') hidden.setAttribute('state', 'on') kvm.appendChild(hidden) features.appendChild(kvm) hooking.write_domxml(domxml) EOF chmod +x 99_mask_kvm
Thanks in advance. Yiimao Yang.
