I’m not going to watch the video, but what’s the procedure for switching between Linux and Windows? Usually you dedicate a GPU entirely to VFIO, with a 2nd GPU for the host OS (or run headless).

Anyway, will it work? Yes, minus some anti-cheat software. Will it be a simple solution? Well, once you get things stable, yes. The tech behind this is mature, but it can be a rabbit hole.

I would look into a non-Nvidia GPU for your 2nd PCIe x16 slot (x4, shared with the 2nd M.2 slot FYI). Good idea to check IOMMU groups before buying anything, but modern AMD motherboards are usually fine. Blacklist the Nvidia drivers and dedicate the 3070 to VFIO to make your life easier, and run Linux off the secondary GPU. Intel A380 might be a good choice. Do gaming stuff on Windows and stream via Parsec/Looking Glass/Moonlight+Sunshine; everything else on Linux.

Keep working on those evil KPIs*, you’ll get there.

*Not to be confused with regular KPIs, which are not required to be evil just usually are.

It’s easy* to setup Hashicorp Vault with your own CA and do automated cert generation and rotation, if you are willing to integrate everything into Vault and install your root CA everywhere. (*not really harder than any other Vault setup, but yaknow). I may go down this route eventually since I don’t think a device I don’t control has ever accessed anything I selfhost, or ever will.

I have a wildcard subdomain pointing to my public IP, and forward port 80 to an LXC container with certbot. Port 80 appears closed outside the brief window when certbot is renewing certs. Inside my network I have my PiHole configured to return the local IP for each service.

Nothing exposed to the internet at all. There is a record of my hostnames on Let’s Encrypt but not concerned if someone will, say, deduce apollo-idrac is the iDRAC service for a Dell rackmount server called apollo and the other Greek/Roman gods are VMs on it. Seemed like a house of cards that would never work reliably, but three odd years later I only have issues if a DNS resolver insists on bypassing my PiHole. And that DNS resolver is SystemD-ResolveD which should crawl back into whatever hellhole it came out of.

They could hijack your site at any time, but with a copy of your live private certs they (or more likely whatever third party that will invariably breach your domain provider) can decrypt your otherwise secure traffic.

I don’t think there’s significant real tangible risk since who cares about your private selfhosted services and I’d be more worried about the domain being hijacked, and really any sort of network breach is probably interested in finding delicious credit card numbers and passwords and crypto private keys to munch on. If someone got into my network, spying on my Jellyfin streaming isn’t what I’m going to be worried about.

But it is why CSRs are used.

Friction between Snap and AppArmor is to be expected. The corporate sponsor of Snap, Canonical, is well known for their icy relationship with the corporate sponsor of AppArmor, Canonical.

Not really, but it’s consistent with my beliefs in life before and during work as well.

I’ve found the idea of LXC containers to be better than they are in practice. I’ve migrated all of my servers to Proxmox and have been trying to move various services from VMs to LXC containers and it’s been such a hassle. You should be able to directly forward disk block devices, but just could not get them to mount for an MinIO array - ended up just setting their entire contents to 100000:100000 and mounting them on the host and forwarding the mount point instead. Never managed to CAP_IPC_LOCK to work correctly for a HashiCorp Vault install. Docker in LXC has some serious pain points and feels very fragile.

It’s damning that every time I have a problem with LXC the first search result will be a Proxmox forum topic with a Proxmox employee replying to the effect of “we recommend VMs over LXC for this use case” - Proxmox doesn’t seem to recommend LXC for anything. Proxmox + LXC is definitely better than CentOS + Podman, but my heart longs for the sheer competence of FreeBSD Jails.

Do you have any trouble with cooling or anything with them? Got like a billion unused PCIe lanes in my Dell R730 and can think of a few things that might benefit from a big NVMe ZFS pool.

What’s the DEAL with WIVES anyway

@TrenchcoatFullofBats I think this is the winning answer. Looks like it’s about a 1060 6GB, which should be enough horsepower for several desktop VMs, and keeps open my full profile slots should I ever want to install something even more powerful in the future. vGPU support is also nice so I don’t have to juggle which VM gets which GPU.

@Nilz Do you know if the WX 5100 supports SR-VIO? Getting mixed answers about what if any AMD GPUs support it, but having VMs share a single physical GPU would be a perfect solution.

@Nugget Yeah an older Quadro like the P600 is the fallback option. Looks like they run about $50 used on eBay.

Actually I lied, according to the Dell manual the full profile slots have a connector that provides PCIe power though I’d have to buy a cable for it. Long term the answer might be to get a used V100 and dive deep into the vGPU rabbit hole (erp).

@JustEnoughDucks I am planning on getting an Intel Arc for my Jellyfin server at some point. Have an old Dell SFF with a 8700 that I think I’ll eventually stuff into a 2U chassis. It’s probably overkill for my VM server though, since the VMs really just need to not lag in desktop application work (aka IntelliJ) and play Youtube videos without obvious framing.

It was never properly contained in the first place.

Only issue I had with a similar setup is turns out the old HP desktop I bought didn’t support VT-d on the chipset, only on the CPU. Had do some crazy hacks to get it to forward a 10gbe NIC plugged into the x16 slot.

Then I discovered the NIC I had was just old enough (ConnectX-3) that getting it to properly forward was finicky, so I had to buy a much more expensive ConnectX-4. My next task is to see if I can give it a virtual NIC, have OPNsense only listen to web requests on that interface, and use the host’s Nginx reverse proxy container for SSL.

FYI the scene this is from. If you “so bad it’s good” media I highly recommend Danger 5. It’s one of the very few things to initially try that and pull it off.

You might know it from this gif.

If you live by a major university, they likely have property disposition where you can pick up slightly older equipment, sometimes for super cheap.

I kinda hate to be like this, but if you are in a tech position, past the early entry level nonsense, and not making six figures (in the US) then you need to be job hunting.

I don’t know if any particular certification will get you there, but IT remains a great practical field to be in. Don’t make any sort of “I’m just in this for the money” apologies.

It’s where a lot of tech employees hang out. You have to verify that you have an email address with the company’s domain to post, but otherwise super anonymous. It can be super toxic and you see a lot of fake posts, plus your account isn’t revoked after you leave the company, but the original OP definitely has/had a Twitter email address.
