I love it. I don’t run across these OSes or distros every day, so when I see that my mom has version “23h2” of windows 11, I know it was last updated in the second half of 2023n so it must be recently patched. Likewise, if I run across an Ubuntu 23.10 install, it’s not any older than October 2023, but the 18.04 deployment is a few years old.
Yes. This is home-made out-of-band management, like HP’s iLO, Dell’s iDRAC, or generic IPMI. Not only is it a virtual KVM (keyboard/video/mouse), you can pass the host’s power button through this device so you can remotely power on or reset a hung or powered-off system, or mount and boot from a virtual floppy or ISO to completely reinstall the remote system.
