Did you ever make any progress on this?

Ran into this problem for the first time today. I was renaming and deleting some empty files on the cache drive when I lost access to all shares. I had a script that was adding and deleting in the same directory. I was using a samba share but the script was on unraid so not samba. I'm using 6.8.3. Weirdly (and fortunately) VMs were still running fine and rebooting appears to have restoreed everything.

Thanks for this!

I'm not sure if this is the same issue since all the hardware is different but recently I was having crashes after reboots with a old AMD card, but only with the drivers installed in the VM. I didn't think it was the reset bug (although maybe in a way it is) since I'd used the card successfully for passthrough tests in the past. What actually solved the problem was ALSO passing through the hdmi audio which I had just left behind before since I didn't need it. I still don't use it but it was stable after this point.

Yeah, we have the GPU drivers built into unraid now so I think we just need QEMU compiled with the right flags?

Now with proxmox: I'm taking a look at that one tonight. I had no real interest in running a Windows server ever again.

If you're looking for a GUI to interact with VM snapshots with today, you can use virt-manager with unraid. That's what I use and I like it a lot. Keep in mind you can't snapshot ovmf machines (that's not unraid's fault its an old bug/limitation with KVM that I'm surprised isn't fixed) and you'll need to change how the VMs are stored because their states will be lost on reboot otherwise. (unraid by default creates its VMs from scratch essentially every time it boots but it has no system to maintain snapshot information). Certainly would appreciate some tools for btrfs though, I have to go all command line with that.

I would like to have wireguard setup to certain VMs (and maybe some dockers but no use case for this right now) connect to the internet ONLY through a VPN like mullvad and other VMs and existing dockers connect without the VPN. I read the thread but I was a little confused about whether that was possible by the end. Basically I want to offload VPN connections to a single configuration location instead of having to set it up on every potential client.

Thanks, I have it working now. Is there a simple way to constrain the server to only my local network? I'm just playing around with it at this point. Perhaps its fine but I noticed the doctor was aware of the WAN IP in the status page. Edit: Nevermind again. I think I'd have to setup my router to forward ports for this to work so nothing to do.

Hello, I get an error that the java path is missing when I try to start. I tried changing it from 8 (what i starts with) to 16 but it didn't make any difference. This is my only docker. The docker is installed on an unassigned devices disk but not sure if that matters. Attached is a log. Thanks Edit: I see there is a post on the top that probably covers this... log.txt

@jwoolen I appreciate this thread since it seems like its the first info I've seen about the iommu groups on rocketlake. Just to confirm, you do not have ACS override options enabled, is that correct? (In other words, these are the true groups?) If so then Intel has finally fixed the broken ACS separation on the root ports. While rocketlake has a lukewarm response to a lot of people, this and the increased lanes for the DMI and m.2 slots make it much improved platform for passthrough.

I don't know anything about this thread but was pinged because of my gvt-g thread. Its also been awhile since I did that. "All" I had to do to get unraid to use gvt-g was rebuild the kernel used with the gvt-g flags turned on as they were disabled in the default build. The qemu version was fine as is IIRC, although it was compiled without openGL support (not surprising) and openGL is required to allow the gvt-g slices to render to a dma buffer which many people make use of with gvt-g. It still had use even without that feature.

Wish they made some of those new cases in white. I'm not interested in building in anymore black hole cases, can't see anything.

@meep I came to the same conclusion on this as you did. The price and availability of working 4 port cards is kind of wonky so rolling your own has some advantages. I use a 4 port mining riser which I bought for ~$15, they're pretty easy to find all over. I seem to have better luck with ones using the asmedia chipset which is what most of them use. Advantages are easier to find and flexibility. You can mix and match devices (including SATA controllers and different types of USB controllers, even video cards). Also you can install 4 port cards instead of needing to use USB hubs, most 4 controller cards only give you one port per controller. Disadvantages are if you're buying all the controller cards from scratch its not much cheaper than the all in one card and it takes up a lot of space and creates a wiring mess. So you'll need a custom case or a case with a lot of expansion slots in many cases. And when using USB 3.0 you have a bandwidth bottleneck. I've never seen an (affordable) mining riser that doees 4x pcie to 4qty 1x pcie splits, they're all 1x to 4qty 1x pcie split. The bottleneck doesn't really matter to me since I really only use USB 2.0 and 1.1 devices.

Anyone get this working with a more recent version of virt-manager? With mint 20 there is not method drop down (~7:35 in video) to pick TCP. Nevermind, I solved this. Custom "URIs" are created for this behind the scenes. I created a connection on my old rig and copied the text. Example: qemu+tcp://[email protected]/system

@0x00000111 Can you show us the device listing/lspci so we can see what bridges and chips it uses? What platform are you running this on? (Ryzen, Intel, what chipset?) Thanks for the update.

My mistake, these cards aren't Startech, they are Syba. They aren't a lot of use for people here perhaps because they aren't 4 USB controllers. I basically use a bunch of them to get SATA ports and USB ports out of all my PCI-e 1x slots. https://www.amazon.com/gp/product/B00MVTB8TK/

Surprised so many people have trouble with these. I own a bunch of startech SATA/USB3.0 combo cards with the same USB controllers and asmedia bridges and they all passthrough the USB controller fine.

Second this, for same reason as Pauven. Its not as easy as it sounds though, because what happens when you change a file on the cache? How will that link up to the array?

Sorry, stock one. There are no nvidia drivers. I tried a number of things yesterday, OVMF VMs actually do work. I'm probably going to proceed with the dummy vm during i915 load. Its kludgy but if its stable I guess I'll be satisfied.

I have a passed through ROM, although that didn't make a difference.

I don't think that is it because its plugged into a monitor the whole time. It also worked reliably until I started this whole i915 adventure. Although maybe there is something going on there.

So this isn't really about plex, but people doing quick sync on unraid have a similar use case to me. I've found that once I modprobe the i915 my nvidia card just gives a black screen when passed through. If I don't modprobe after boot it works fine. In my case the igpu is primary, nvidia is secondary. I found if I pass the nvidia through (so its in use) and then modprobe, things are OK. Based on that I added nvidia to vfio pci ids in syslinux.cfg, and confirmed vfio was in use at boot. The modprobed but it still broke nvidia passthrough! This is perplexing to me. i915 shouldn't be able to taint the nvidia card in my mine, since its not a compatible driver. I assumed all the displays were reignited or something when the driver loaded and this was tainting the nvidia card somehow, but if its bound to vfio I don't see how it should be able to get at it at all. I think I can workaround this with scripts and a dummy vm to "protect" the nvidia card from i915 but that seems ridiculous. Anyone else seeing this behavior or is it just me? I've only tried nvidia on seabios vms so maybe that is a component.

@segator , did you ever find decent instructions on a custom kernel for unraid? I'm in a similar kind of situation. I would like to add some modules to test something before making a better request.

For the Intel GVT-g (mediated virtual GPUs) I think all that is needed is for these modules to be included: kvmgt vfio-iommu-type1 vfio-mdev I wouldn't ask for a whole web GUI, I'd be happy if I could play around with it editing XML and generating the mediated devices from the command line.
