Hello everyone,

 

Just installed a brand new Windows 10 22H2 Enterprise virtual machine on unraid 6.11.5. I tried starting the virtio-fs service and I get this error

 

Here is the VM xml

Thank you

I found out I need to manually install WinFSP first. Followed this guide here:

https://github.com/virtio-win/kvm-guest-drivers-windows/wiki/Virtiofs:-Shared-file-system

 

Could be marked somewhere in the template gui that something is missing and must be installed for it to work

Hello

I have configured Virt-manager with W11 Virtual machine and want activate VirtioFS to have a shared folder between Host and VM

I have installed lastest virtio driver on W11

I have enable memory shared in virt-manager in the VM options

I have added new material file system shared and configured it

Anyway, I can't start the VM with this error in attachment.

None IA can help.
