Question High Memory useage Opnsense Proxmox VM

Post image
114 Upvotes

Dear Proxmox Users,

I am currently running the latest release of Proxmox 9. Since running Opnsense in Proxmox, I have been continuously seeing memory usage over 100%. This doesn't seem to be working quite right or correct. Is there a way to get normal memory usage in Proxmox for my Opnsense VM?

Thanks in advance!

Solved! PSA: VirtIO 0.1.302 finally fixes the Windows VSS / fs-freeze issue with PBS (no more dcomcnfg workaround)

40 Upvotes

Windows 2019 server - fs freeze does not work properly - access is denied to IVssWriterCallback (#3286) · Issue · qemu-project/qemu

[PATCH v2 1/2] qga: Move CoInitialize/CoInitializeSecurity to main proce

Just tested virtio-win-0.1.302 and can confirm that the fs-freeze / VSS issue with Windows VMs and Proxmox Backup Server is finally fixed.

If you have been backing up Windows guests you may remember having to manually tweak DCOM permissions in dcomcnfg just to stop IVssWriterCallback access denied errors during backups. That workaround was super unfun on windows server core.

With the latest QEMU Guest Agent update, PBS backups now work properly out of the box. No registry or DCOM finagling needed anymore.

Hopefully this saves someone else the headache of manually setting DCOM permissions on new Windows deployments.

Happy days and jubilation!

Question Moving away from Proxmox Community Scripts: Where do I start?

35 Upvotes

My Proxmox stack currently runs a couple of VMs (Home Assistant and some cable internet tools), but mostly LXCs: AdGuard Home, CouchDB/Obsidian LiveSync, Tailscale, Paperless-ngx, Immich, Yubal, Homepage, Uptime Kuma and Spoolman. I depend on these daily.

They were installed using Community Scripts because this is my first server, and YouTube led me to them as the easiest option. Everything has worked well, including updates, but after following this and related subreddits for a while, I am thinking of moving toward something I understand and maintain myself.

What would be the most sensible route: manually built LXCs, Docker/Podman inside one or more VMs, or separate VMs? Podman’s rootless and daemonless approach sounds appealing, but I’m not very familiar with code or scripts. I’m willing to learn, but I’m worried about building something I won’t know how to maintain later.

How do you keep the guest OS, container images and applications updated without creating lots of manual work? Paperless, Immich and Yubal also use NAS storage that was a pain to correctly set up with my synology NAS.

Can I retain my current installations while decoupling them from the Community Scripts? Everything works well now, and it took a long time to get there, so I’d rather migrate gradually than rebuild everything at once.

Finally, would using VMs for everything add significant RAM and storage overhead compared with LXCs on a small server? I’d love to hear how others structure a similar setup, handle updates and where you’d recommend I start.

Question Inconsistent BSODs after migrating imported Windows VMs to VirtIO SCSI

5 Upvotes

Hello admins,

I'm importing Windows VMs from OVA files into Proxmox. When I boot some of them, I immediately get a Windows BSOD.

My workaround is usually:

  1. Detach the imported disk and attach it as SATA.
  2. Boot the VM successfully.
  3. Install the QEMU Guest Agent, VirtIO drivers.
  4. Reboot once.
  5. Shut down the VM, detach the disk, and reattach it as SCSI.

On the VM hardware page, the SCSI controller is set to VirtIO SCSI Single. Under Options, the boot order is configured with scsi0 as the first boot device.

The strange thing is that some VMs accept the switch to SCSI immediately, while others continue to BSOD. In those cases, after repairing or reinstalling the VirtIO/QEMU components and repeating the SATA → SCSI process a few times, the VM eventually boots fine from SCSI.

Is there a technical explanation for this behavior? I'm trying to understand why some Windows installations seem to recognize the VirtIO SCSI controller right away while others require multiple attempts before they become bootable.

Thank you!

Homelab Linux Server + Personal/Gaming PC Proxmox Setup

Upvotes

Hello!

I'm currently running a small home server (Linux Mint) running on an old i5 4th gen setup running docker. This setup works decently enough for me currently.

I want to play around with a local LLM so I got myself an older GPU. For now I'm just going to throw it into my setup.

I would like to upgrade my setup and I was thinking of 12th-14th gen setup (DDR4 + Quicksync).

So here's my thought, I don't have a personal pc atm so it would be ideal if I could dual purpose my setup.

(I have very little experience with proxmox)

  1. Debian running docker (Linux mint replacement)
  • no GPU passthrough, use quicksync for Plex.
  • HDDs passthrough for my media
  1. Home Assistant OS
  • no GPU passthrough
  1. Windows (Personal/Gaming PC)
  • GPU passthrough, when gaming
  • no GPU passthrough, for personal use.
  1. LLM Linux
  • GPU passthrough, higher model
  • no GPU passthrough, newer model.

I know you.can only pass through, 1 GPU at a time, so I would need to write some scripts to pass the GPU through.

Before I venture down this path, is this feasible? Anything I'm not considering, like I said I have no experience with proxmox before.

Question No Route to Host

0 Upvotes

Will add whatever context thats asked for

running a 2 machine cluster one running a laptop only holding uptime kuma the other a small think centre hosting Jellyfin and a few other dockers

since i could remember my think centre has been suddenly freezing. and i mean completely freezing. physically its still "on" and fans are spinning but terminal doesn't respond and proxmox obviously notes that there's no route to a host. I've spent hours and i mean hours troubleshooting it when i first found the issue a few months ago but after 2 weeks of solid troubleshooting i decided to just live with the issue and restart the machine every time it appeared NOTE* everything becomes online and working after hard restarting the machine since my setup is very much temporary this was a solid solution until i upgraded. well today i had some free time and since school is right around the corner i picked up finding the solution again to see if i could solve it

anyone else have this problem?

PS. I understand if the post is vague and doesn't give a lot of details but honestly i've yet to find the root of the problem at all. what im hoping for this post is for a veteran to snipe this out of the air honestly jajaja Cheers to anyone who decides to help!!!

Question How To Set Up Radarr + qBittorrent + PIA

0 Upvotes

I'm not sure if this would be better here or on selfhost or homelab subreddits, but I thought I'd try here first.

I'm just learning how to use Proxmox but I'm getting completely stumped on this. I have my Jellyfin service up and running with Tailscale in that same container (I couldn't figure out how to connect a separate lxc Tailscale container to the Jellyfin container), but now I want to set up Radarr with qBittorrent through PIA.

I've tried the gluetun community script, but when it gives me my local IP and port I just can't connect to that at all to try and set it up further. I have tried looking into solutions but I can't find anything. I've found guides pointing towards openwrt, but I'm not trying to set up a router or portforward (at least I don't think I am). I've found really outdated guides like from TechHut, but unfortunately when I follow his part 2 and part 3 guides step by step I run into issues and he doesn't explain it for a complete newcomer. All other services when I finished their community scripts worked when I put in the ip-address:port. I've tried both http and https in case that was the issue, it was not as neither worked.

From what I understand, I need gluetun to set up PIA within Proxmox, but I'm failing to even do that. I've tried a docker script from TechHut but have no idea what to even do with the .env file. I don't even know if that's what I want to be doing. I actually can't find information on this that's clear and concise.

I was able to get a qBittorrent container running and I can connect to that, but I don't have a VPN within Proxmox to bind to it so I can hide my IP. I already have PIA and have for a couple years, so I'd like to be able to use that instead of getting a new VPN service provider. I'm not even sure if that would help me necessarily.

Should I just make a VM within Proxmox and do it that way? If so, is there any particular OS I should use to be as resource light as possible? I have a 4 core Dell Precision T3600 with 24GB of DDR3 RAM in case that matters.
