Also agreed. Not sure why this isn't already a thing

Are you not passing through the audio portion of your 3060? There is also a mismatch with the CPU pinning. Your XML shows 10 cores passed through, but the CPU Pinning screen shows 12. You could also try an emulatorpin assignment. I found that using a Q35 type is snappier than a i440fx, but that might be just my setup. Try the MSI Fix?

"system image must be used with IDE controller". It also might be helpful to try "USB" as the file looks to be an .img not an .iso (unless you converted it)

That is the infamous Error Code 43. Lots of resources if you do a search in the forums for that

Windows Server has a 180-day free trial, if you haven't used that up yet Ubuntu server has a bit of a learning curve over Windows Server because of the lack of GUI, but I would strongly suggest that you take the time to learn it. There are a LOT of helpful resources a google-search away, and you'd be surprised how much you learn carries over into other areas

You only need to add multifunction for the first entry. Not sure if that will fix your problem or not

Is your VM set to sleep after a certain amount of time - because that will cause the pauses as well Disable sleep and hibernate if it isn't already

The i3-3220 does not support VT-d, which is required for passthrough to work

When you say "nada", what does that mean? The VM seems to boot okay but no video output? You get an error popup in unRAID? The VM icon spins but drops back to stopped? There isn't anything obvious in the XML that I can see. Is it your only GPU, because if not you may not need to attach a VBios. I'd also make the GPU a multifunction, but that shouldn't prevent anything from booting. I can see your passing through a GPU, but not a keyboard or mouse. Is that on purpose? What if you create a new VM and pass the GPU through right away? Just to see if its a GPU, unraid, or Windows issue

Modern cards are pretty good about idling-down when not in use. My guess is the card may use <5 watts just to keep the 'idle' circuits energized, but its really not enough to worry about.

"Failed to find romfile" Are you absolutely sure the file is where its looking and its name is correct (capitals matter). You could try changing the filename to something a little simpler as well - I don't know how the code handles an equals sign, for example. Its probably fine, but I like to address the simple things first

You can also download it straight into the VM and extract the drivers from there. That avoids any messing around with the VM settings. That being said, if everything is working properly there usually isn't much reason to update the drivers.

Is your VM trying to hibernate or go into standby? I've had issues with VMs waking back up when they do.

Does anyone know why SSD Trim spins up my whole array rather than just being confined to the cache drive?

Are you referring to passing through the 2 ports on the motherboard, or do you have an additional dual-port NIC to pass through?
