I want to start by apologizing if this sounds dumb.  I've done my best with my knowledge and research to try to fix this but I cannot find a solution anywhere or with anything I've tried.

 

I run Unraid 6.12.13 and inside it a Windows 10 VM hosting my ARR suite.  The way I have it set up is the ARR suite is on Windows 10 VM, downloads the files to a folder within the VM then moves them over to the appropriate Share, which I have each share mounted as a network drive.  Everything was set up and working fine for a few months until this past weekend when I noticed that the files were no longer copying from the VM to the Share (the size of the file doesn't matter either, it can be a text document or multi-gig video file, the results are the same).  I cannot copy anything from my Windows 10 VM to an Unraid Share, however copying anything from an Unraid Share into the Windows 10 VM works fine.  It doesn't matter if I try to do it within the VM to the share, or if I mount my VM folder with the downloaded files as an SMB share then try to move the files through Unraid.

 

Simply put: Everything was working fine then something changed (unknown what) and files transfers from Windows 10 VM -> Unraid Share do not work in any fashion, files transfers from Unraid Share -> Windows 10 VM work fine.

 

I've attached my diagnostics from Unraid but I'm willing to supply any other information that could possibly help me fix this.  Thank you!

See the release notes, there's a known issue with the virtio network driver, change it to virtio-net and it should fix the problem.

Wow I feel like one of the dumbest people ever... I can't tell you how many versions of virtio drivers I tried on my VM but didn't think of actually changing to virtio-net drivers.  This fixed it immediately, thank you so much.
