Some more information: I was able to snapshot a Linux guest VM with no issues. I also got more options to use the ZFS native snapshot, which I don't get when trying to do the Windows VM. I do see the Linux VM has qcow images for hard drive, while the Windows VM has .img files. Not sure if that matters?

Hello, I'm trying to create snapshots of a windows VM that's hosted on a ZFS drive. I have 744 GB free. The VM itself is several TB, though most of that is in a secondary drive (it's a gaming VM, all the games are on the second drive). My understanding is that a snapshot is only a diff anyway, so it doesn't need to clone the entire disk. I would think that the 744 GB would be sufficient space for that, especially considering not much changes on it now other than updates, but when I try to create a snapshot I get an error for insufficient storage. I need more information on what the hangup is-do I need room for a full clone? Can I only snapshot the (relatively small) system drive? Any advice is appreciated, thank you.

Thanks for the lengthy reply. My understanding is that ZFS now supports officially the ability to expand a pool. It sounds like that’s not yet implemented in unraid. Annoying, because I had data on that disk that I couldn’t back up elsewhere before creating the pool. My plan was to create the pool, copy over the data, then add the disk to the pool.

Thanks. Not the answer I wanted to hear but I appreciate the clarity. is there an unsupported way to do what I’m trying to do? or an I just SOL for now?

I have a zpool of 3x2TB NVME drives. I would like to add a fourth. They are all the same drive from the same manufacturer. I'm trying to use zfs attach and getting an error of cannot attach nvme-eui.6479a78dd00000d8 to raidz1-0: can only attach to mirrors and top-level disks I've tried doing it from the GUI as well and just get 'invalid expansion'. What is the supported way to do this? Thank you.

Cool, so my plan to triple it will pay dividends. Thanks for the help! BTW, for anyone reading this, I've definitely seen a performance IMPROVEMENT in my VM with less RAM allocated to it. That's counter-intuitive, but true. To JonathanM's point, I'm sure the bottlenecks I was experiencing were on the UNRAID side and not the VM side.

Thanks for explaining. Do you know how much RAM is optimal for the host? Or at least a guideline? After my upgrade I’d like 32gb for my windows vm.

I’ve got a daily driver/gaming vm that works great. What I’m wanting to do is use a share to store games so that I can expand it. I’ve got a couple nvme drives as a share, but I’m noticing some hitching in game and I think it’s because I have an smb share mounted for storage. Is there a better way to do this? I’m trying to avoid creating a vm disk because I want to be able to use the drives for storing multiple things without having to define storage limits, if possible.

Yup that seems to have been the issue. I must have over provisioned it. Good solution, thank you. I ordered 64GB more RAM on a good deal, so I should be able to run a couple VMs simultaneously in the future.

I have an Intel 12700K, 32GB of RAM, and. 3060TI in my desktop. I’m sharing that with a windows 11 vm that has passthrough on a nvme drive and the video card. It’s super stable and works great. UNLESS I also spin up my Linux VM with a VNC desktop-then they both crash within about 2 minutes of Linux getting to desktop, even with both running at idle. I believe I have not over provisioned(not even sure if that’s an issue assuming low actual usage?). I have selected separate cores on the processor for each. The RAM amount is less than 32GB total. It doesn’t seem like anything a problem until the desktop starts stuttering and then black screens and crashes. Both VMs crash according to web UI. I don’t think there’s a reason I can’t run multiple VMs…I’d really like to be able to use Linux for development work and as a secure environment. Any help is appreciated.

I have an MSI z690 motherboard (this one) and I want to passthrough audio to a Windows VM. However the audio card is part of an IOMMU group with some other devices, and I'm not sure I can pass through the group without causing myself issues. Would it cause issues to try it?

I have qemu installed, didn’t change anything

I’m trying to remember now. I’m wondering if windows worked so well out of the box that I forgot to do that. I’ll check. Thanks, that gives me a place to start.

When I click on 'Stop' in the VMs tab, I would expect the Windows VM to shutdown gracefully. However, nothing at all happens. I'm trying to be able to run a script like spaceinvader1's that switches between VMs (I use this as my main desktop with GPU passthrough on multiple VMs). Any ideas what I should check, either on the host or the guest, to get this working?

nginx manager is a gui for nginx. It obfuscates a lot of the manual work, which is great 99% of the time. you just select url/ip/port and hit save. Only problem is if you need custom locations, it would be easier to just do it in a .conf file. I'll see if I can figure it out on my own for this one though.

OMG man let it go. Your posts are at the point of being unhelpful. We know there are guides out there for VPNs. That's a good solution for some people. Reverse proxies are also a good solution for some people. Yes, it takes correct setup as does anything. A warning about that is warranted, but you're well past that. A properly secured 2-factor authentication gateway (such as Authelia) along with HTTPS certs should be more than enough to secure the reverse proxy. No, not everyone will do that, but that's not your responsibility (and if you're reading this, PLEASE setup your reverse proxy with this kind of security, or consider not doing it at all). Off the top of my head, a couple valid use-cases: Local network only, to avoid having to remember all the ports and IPs for all your applications Remote access where a VPN isn't viable, for instance on a work PC without admin access In the future, please consider just answering the question, or don't respond. Thank you.

Any idea where all of this goes in nginx reverse proxy manager? I like the manager gui because it makes life easier, but when it comes to advance configs it can be a pain...

I’m doing a GPU passthrough gaming VM build. Hardware: i7-9700K ASUS Prime B-365 Rtx 3060TI Razer Ornata Razer mamba wireless During games, moving the mouse causes severe lag and slowdown (sometimes to the point of freezing video output entirely). I’m getting very sub-par performance, for instance 20 fps in Cyberpunk on very low with rtx off. Moving the mouse causes the screen to freeze entirely until I stop moving the mouse. The gpu also sits at 40-50% load while under performing as reported by nvidia geforce overlay. Of course i have latest drivers installed etc. since I’m passing through the usb controller as well, I’m wondering if there’s interference between usb controller and pci-e? I don’t know if that’s even possible but I can’t figure out how moving the mouse freezes game video output. Desktop performance and anything that’s not gpu-intensive works perfectly fine.
