virtiofs Illegal Seek Error because of ivshmem device of looking-glass
Description of problem:
tl;dr: The dev "gnif" from looking-glass does not want to analyse this problem which his config from the documentation is causing. He insists someone opens a issue here at qemu's, so thats what i did now :) He also insists this problem is not caused by his config (even though the config is needed for looking-glass) and does not want to help or analyse this whole mess. Sorry if i'm a bit salty.
Please see the following issues on his and the virtio-win github : \
https://github.com/gnif/LookingGlass/issues/1089
https://github.com/gnif/LookingGlass/issues/1083
[https://github.com/virtio-win/kvm-guest-drivers-windows/issues/911](https://github.com/virtio-win/kvm-guest-drivers-windows/issues/911%5C)
#
Steps to reproduce:
1. Create a VM
2. enable looking-glass (i used the latest Beta6 release from github) with the mentioned kernel module (i use manjaro and can use looking-glass-module-dkms from AUR)
3. add virtiofs from virt-manager
