If there was a rpi hat that had multiple connections I would probably use it, a $300 avocent 24 port KVM w/ html5 interface is much more cost effective than 24 pikvms, etc.
Maybe for some context - although Jeff Geerling does provide it too in his video - most 'server' motherboards have build-in KVM.<p>I will make the bet that build-in KVM is more responsive and those interfaces are now HTML5 based, so no nasty Java applet stuff.<p>Motherboards / servers with KVM will consume around 8-10 watt extra, even when powered off, as the KVM solution is basically a tiny computer running Linux + proprietary software, soldered on the motherboard.<p>Motherboards with KVM support also support IPMI or redfish for remote management. For instance: I use IPMI to force a physical machine to PXE-boot into an automated installer, to provision the OS.
Jeff Geerling just writes "including BIOS/UEFI". In my extremely limited experience without deep insight it works with some computers while on others the BIOS screens remain black (while the Linux console works correctly). We got it for BIOS work, but that plan did not really work out.
I wanted to implement a KVM on my pi (a while back). I had the usb hdmi capture dongle. What prevented my from finishing the project was getting power in and usb out on the pi connector.<p>It required a custom cable that I didn't want to build myself. Are cables of this type more readily available now?
How does ipmi on servers provide video? I thought u just plug a specific Ethernet jack into a different lan?<p>I'm asking this because the pikvm takes HDMI input so I'm wondering how does ipmi manage the video
