Prevent error on windows virtiofs mount

[z0rb]

After installing WinFSP and the virtiofs driver in the provisioning phase, then configuring the service to autostart with sc config VirtioFsSvc binPath="C:\Program Files\Virtio-Win\VioFS\virtiofs.exe" start=auto depend=VirtioFsDrv ... the virtiofs share gets mounted as a separate drive in Windows 10.

I have no experience writing vagrant plugins. In my fork I have just tried to implement a NOOP so that the libvirt plugin doesn't error out because of the missing guest capability. This works for me as vagrant up succeeds and the share works properly.

Question for maintainers. Would this be ok to merge into main, to prevent the error? The capability obviously exists, but I do not know what would be acceptable for main.

[github-actions]

A docker image containing the code from this plugin to allow testing locally without installing
can be pulled from: ghcr.io/vagrant-libvirt/vagrant-libvirt:pr-1793-slim

If you need the image with the full dev toolchain, you can instead pull: ghcr.io/vagrant-libvirt/vagrant-libvirt:pr-1793
