mklink/symbolic links in Win 2012R2 guest

[hight]

I would like/need to move some rarely needed (big) folders to a network share in a 2012R2 guest on Proxmox 5.2.
Always use mklink on bare metal which works fine but I didn't had any luck in a VM yet.

mklink /D "C:\Program Files (x86)\Windows Kits" "Y:\Windows Kits"

Folders show up and some folders work fine but specific ones fail with "Path not reachable.


I suspect an issue with the underlying Linux host filesystem like https://kb.vmware.com/s/article/2123633 but couldn't find anything related to KVM. Does anyone had more luck on this topic?

just in case anyone else has this issue: It works if a new virtual disk on the network share is added in proxmox. mklink works fine on this disk.
