Thank you for the advice. I would like to try this. How can I implement iSCSI on unraid? Will this allow for me to share the same game data between several gaming VM:s? Can the VM:s be on at the same time?

Hi! I have 2 gaming VM:s with two GPU:s passed through to them (one for each). I would like to store all games on a single virtual disk and clone the disk for the other VM, so that I do not have to install all games twice, and could thus save space. Preferably, one disk would be the "master disk" and when games are added or updated on that one, it would be nice if these updates could be easily propagated to the other VM. - However I am not sure how this would work with game saves etc. Both VM:s already have an OS drive (virtual), that I am thinking I should keep, and where save data etc could be saved, but I am not sure if game saves can be easily separated from the game files (I am using steam and blizzard games at the moment). Before, I used btrfs and the "cp reflink" function, but the disks go corrupted after a while. Maybe btrfs is not stable enough to do this? So I thought that zfs could perhaps be used instead? However, I have never used zfs before so I would like some advice on how to set it up. I have a 1 TB SATA SSD that I am planning to use for this. And I have installed the zfs plugin for unraid. Thank you in advance!

Hi! just curious - what are you using this for? /Erik

+1

+1! However, I have a feeling that this feature is not possible for the unraid devs to implement

I would love this feature

No ideas? How do you all create your VM:s? I am looking for expert tips...

VM creation takes a lot of time... 1. Using the GUI to set the number of cores, RAM, create vdisks etc 2. Running through the OS installation 3. Install necessary drivers, programs etc and adjust settings This is a hassle when you want to create a VM just to test something new... Is there a way to speed this up? Lately I have started using reflinks since my VM disks are on btrfs pools (cp --reflink /path/to/old/VM/vdisk1.img /path/to/new/VM/vdisk1.img). This saves HDD space and gets rid of the need for step 2 and 3, but I instead need to have base images that I can clone from. Is there a better or more accepted way to quickly create VM:s? Are there pre-installed vdisks available for common OSes like ubuntu/centos/windows10? Cloud providers let you create VMs by clicking a button in the web GUI and wait a minute or two but I guess unraid was not designed for this... Happy to get any suggestions!

Awsome work!! Got it to work with Radeon Rx580 passthrough as well. Nice to be able to explore the new win11 however I can not say that I am very impressed with the new features so far. It looks mostly like a pretty skin on windows 10 and microsoft trying to steal more of my privacy.

You saved the iso in /mmt/user/isos/ but you look for it in /mnt/user/ISO…

I agree this is a cool idea to try out. Both proxmox and unraid uses kvm so it should be possible?

Same error for me today. Could not even download diagnostics until I restarted nginx. monsterservern-diagnostics-20210707-1012.zip

Wow this is awsome! Great work crenn! I had lost all hope of solving this problem… I have upgraded my system and sold the huananzhi board already but I will save this post in case I decide to build a second system in the future. /Erik

After many hours of trying to get my GTX 1070 ti to work, your guide finally made it possible. I almost gave up... Thank yo so much!

Thanks! I have seen the taichi guide and followed it. My bios is updated (a couple of months ago when I bought it) and I did the settings and xml he recommended. the other thread about the 5.8 kernel was very interesting though! I have also tried passing through onboard audio before and it resulted in the server hanging completely as well. I would like to try to upgrade but I saw that some people have troubles passing through hard drives via id (/dev/disk/by-id/XX) after upgrading so I would like to wait since I use that for my VM. Also I have a LSI 9211-8i SAS controller and some SAS-controllers stop working with beta 29 (not sure about mine though).

Thank you. Both the usb and wifi controllers are isolated and passed through to the VM. The mouse is connected to the passed through usb ports.

Does anyone have any suggestions? As I wrote I am able to pass through USB and the WIFI from the motherboard and they work, but as soon as I try to install any drivers (mouse drivers for a mouse connected to the USB or wifi/bluetooth drivers) I get a BSOD.

I have a windows 10 VM with a logitech mouse attached to it via usb pass-through. It works fine, but when I try to install the drivers the VM hangs with a blue screen. The same problem occured earlier when I tried to install drivers for wifi/bluetooth that is passed through from the motherboard.

Hi! I rebooted normally (just like someone else in this thread) and the start button is back. Just wanted to post my diagnostics in case someone was interested in investigating this bug. I am also impressed by the speed with which you people reply in this forum! Thanks.

Hi! Same error here. I switched out an unassigned HDD for an SSD and in that process I acidentally unplugged my parity drive. Started up the server and realised. Shut it down, plugged the parity drive back in and restarted. The parity drive is now back but the array start button is missing. See screenshot and diagnostics. monsterservern-diagnostics-20200321-1351.zip

Hi! I have done some more digging. The problem seems to be with dmidecode, the command that the unraid GUI uses to fetch system information. When I run dmidecode manually I get some output and in the end the following error: Invalid entry length (0). DMI table is broken! Stop Is there a way to fix the DMI table? Only through BIOS update? Thank you! /Erik

OK, thank you. It seems like it would be easy to fix, related to how Unraid processes the system information?

Thank you. Yes I can assign more than 32 GB of RAM to my VMs.
