I know this might sound naive but for those of us who had to google kvm here mean keyboard video and mouse, not the linux kernel-based virtual machine kvm this device apparently is used to connect to machines remotely over IP

I thought that was RDS (remote desktop).

RDP is over network, which doesn't work well if your need to access a machine that doesn't have a working network stack because you're troubleshooting a hardware failure, early boot failure, OS provisioning, etc.

KVM can also be nicer than RDP for certain multi-box workstation setups that need high bandwidth and low latency.

No out of the box TailScale but it's 'easy to add.' WebRTC is neat. It looks like it relies on CloudFlare WebRTC relay for STUN / TURN, but supposedly you can self-host the cloud api. https://jetkvm.com/docs/networking/remote-access I'd also point out the gl.inet Comet Pro, which has some nice to haves like wifi 6, full sized HDMI ports, HDMI and USB pass through. https://www.gl-inet.com/campaign/gl-rm10/ The PiKVM a…

Hopefully you are in a network that allows P2P! Then STUN just works and you can use any of the public servers (CloudFlare, Google, Twilio...)

Running your own TURN server would be trivial also. I have been tempted for a long time to make a 'TURN in a Box' that does autoconfig so people can run it easily on Hetzner/AWS

Provenance and trust are relevant for a remote KVM. But I can't find any information on their Web site about who runs the JetKVM company, not even a partial name or handle of anyone, nor even what country they are in. Which seems odd for how much this product needs to be trusted. Searching elsewhere, other than the company Web site... Crunchbase for JetKVM shows 2 people, who it says are based in Berlin, and who also…

It does share similarity to a rebranded Sipeed NanoKVM model already sold in China.

Would have to dump the flash with proper tooling, and load up a clean OS on a blank chip to even begin checking for issues. Mostly, these gadgets are purposely built like garbage for a number of reasons.

If I needed a DIY KVM install for a home-theater, I'd just setup a https://pikvm.org/ install. =)

Just a FYI - many people[0] (including myself) have had serious issues with JetKVM. In my case, I found it is not compatible with all HDMI sources but others just have unknown "Loading video stream..." issues. [0] https://github.com/jetkvm/kvm/issues/84

I’ve been using the glinet comet kvm for my homelab and have no complaints. Their cloud is optional and I don’t use it. The built in tailscale client does what I need it to. I use it with their ATX power accessory to manage physical power on/off when needed.

Given that these things have bare metal access, keeping them off of the public internet seems wise no matter what though.

Earlier quoted context omitted.

Something like Intel AMT? Some prosumer motherboards like ASRock Rack have out of band management controllers in them.

Yes - but a bolt-on solution for nearly any motherboard with an extra PCIe or NVMe slot.

I’ve seen raspberry pi based kvms that do just this - draw power from PCI to operate. Except they still usually require a cable to HDMI/USB ports on the computer. I suspect you’d like to have the whole thing to be on card without cables.

Example: https://geekworm.com/collections/pikvm (but I think this still requires separate power)

To do this, wouldn’t you effectively need to make a graphics card (VGA would work) where a separate chip could read the screen buffer? And somehow get this card to display preferentially over the on-board video card?

I’m sure the all in one card version exists, but honestly a cabled version seems more robust (w/o vendor support that is).

I think products like JetKVM are targeting hobbyists and small outfits; corporations who aren't on a public cloud are using stuff like idrac, ilo, or dedicated rackmount KVM hardware.

IDrac often demands that the PC connecting to it be on the same network however, an rkvm like this let's you skip the pc-in-the-middle step.

This guy on YouTube made several videos reviewing these and also doing some WireShark analysis, also on NanoKVM.

Personally I'd never use these on an interned facing network. But they can still be handy for local only.
