Virt-Manager Failed to Initialize Virtio-9p-pci

Does anybody know how to fix the following error message in Virt-Manager regarding a missing "virtio-9p-pci" device as soon as I attach a filesystem shared folder and I want to start my virtual machine? I tried already to load the module via modprove but it doesn't exist.

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/", line 91, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/", line 127, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/", line 1355, in startup

    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)

Actually I'm assigning 2 physicall hard drives (partitions) directly to my VM for data storage (RAID1 btrfs). But I wonder if it is possibel to do it with the filesystem export function in Virt-Manager as I could have a more simply setup. And setting up a copy of the VM as a test system would allow me to simply change the filesystem to readonly.

Re: Virt-Manager Failed to Initialize Virtio-9p-pci

Not sure if you ever found the solution, but for me I had to modprobe `9pnet_virtio`.
