Hey OP, I was reading your linked HomeLab article and you mentioned you'd rather have gotten a mobo with integrated GPUs next time.

Actually, motherboards do not include integrated graphics, it's all in the CPU/APU. The mobo you linked would not provide graphics either.

AMD unfortunately does not have a high end APU released to consumers right now (there are some 4000 series, but only to OEMs I believe). However, for a HomeLab setup, you might find a cheap GPU to be useful for many things (including hardware video transcoding).

This looks great. To be useful in the datacenter environments I work in such a device would need VGA capture, though. Most servers don't have HDMI ports in my experience. Anybody know of a good, cheap V4L2 USB-based VGA capture dongle?

Not sure if they are still easily available but look into https://blog.benjojo.co.uk/post/userspace-usb-drivers.

Author here. Happy to answer any questions or take any feedback about this post.

Really nice, exactly what I need just now as I'm setting up a remote workstation/part-time server at my families farm, but did not have a motherboard with IPMI/iKVM at hand.

Oh, and thanks for using Proxmox VE! Was positively surprised when I saw our installer flash up out of nowhere :)

This is pretty cool (for managing servers cheaply), but I remain disappointed that remotely controlling computers over a network with low latency is still a difficult task. I've been trying to find a way to use a bunch of machines remotely over my LAN (for gaming / media playback on multiple devices), and have been somewhat disappointed at the quality / latency of the various options I've played around with. It's esp…

Steam link does it, and fast enough to play games with no noticeable latency. Not sure what the magic is, though.

the latency is absolutely noticeable, the human brain adapts quite well though. i've switched mid-playthrough of ori and the blind forest (highly recommended btw) from a link to native 144hz and was blown away how easy the game has become :)

the point still stands: most games are very playable via a steam link.

SPICE (virt-viewer) performs well enough for my every day web browsing with VMs. The performance is annoying but adequate over wifi/WAN.

I'm curious how well this works over a LAN - over a WAN, my expectations are way lower because of actual limitations from going over the internet, so I'm fine with some latency / quality loss.

Sorry, I was trying to imply that it does work great over a wired LAN. I run my everyday browsers on a separate physical machine, communicating over gigabit ethernet. Videos with sound generally play fine, although I often youtube-dl longer ones for usability's sake. The main source of flakiness I've had is from opening too many tabs in low-memory VMs.

This looks awesome. I was looking for a solution like this last year. I budgeted a few hundred bucks but couldn't find anything. Ideally would have a way to handle a few different boxes. I did see something called Intel AMT, part of Intel vPro. https://www.howtogeek.com/56538/how-to-remotely-control-your... Does anyone have experience with this? (I have AMD box so doesn't help me) - actually looks like AMD has simila…

AMT is great. I use it with https://www.meshcommander.com/ - though learning how to provision the machine correctly in Admin Mode so it doesn't pop up a pin-entry screen on the remote end is "fun"!

Cool project, but what about power management? What happens if the PC being controlled crashes and does not let you reboot it using keyboard shortcut? I'm might be damaged by testing and working with embedded development.

Thanks for reading! > Cool project, but what about power management? What happens if the PC being controlled crashes and does not let you reboot it using keyboard shortcut? Yeah, that's one of the limitations. TinyPilot can't control power for the target computer. I don't know of any way to manage power without connecting the Pi to the target machine's motherboard, but that increases complexity significantly. I'm usi…

hook up a gpio pin to a reset switch jumper somehow?

I just set up AMT for a bunch of servers.

It is possible but extremely tricky to set up AMT headless on a self built Intel. You basically need to press keyboard keys at the right time. Too challenging without a display.

Devices don’t load AMT configuration from USB by default unless a vendor configured them to. In which case the vendor just ships you AMT enabled in the first place.

Better to just image the disk on a different computer.
