handling unsupported passthrough of host PCI [solved]

#1 Post by daggs »

Greetings,

I have a freshly installed debian stable on this cpu + mb combo (Intel® Pentium® Processor G4560+H110M-A), installed the needed pks to use virsh, I've enabled vt-d in the bios and verified vmx exists in /proc/cpuinfo. in addition, I've added intel_iommu to /etc/defaults/grub and ran update-grub.
I've created a xml file for a virtual machine to which I want to assign an additional pcie based nic on the mb via full pci passthrough but when I try to create the vm, I get the below error:

Code: Select all

$ virsh create img.xml
error: Failed to create domain from img.xml error: unsupported configuration: host doesn't support passthrough of host PCI devices
what am I missing?

Thanks,
Dagg.
