[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Some feature requests for guest consoles
Hi, Mike H <mikeh@xxxxxxxxx> made a feature request in: https://lists.xenproject.org/archives/html/xen-users/2022-03/msg00009.html for the Xen guest console as connected to with "xl console" to correctly support the terminal size rather than always being 80x20. Additionally I wondered about some other features: - Ability to remap the "magic sysrq" key combination which is ctrl-o, and possibly disable it while leaving "xl sysrq" and /proc/sysrq-trigger in the guest generally working. Reason: guest administrators are often inexperienced with the details of Xen. ctrl-o is a bad choice because it's actually the "save buffer" shortcut in the popular editor nano. On more than one occasion I have had guest administrators be editing a file with nano on their console, they go to save it with ctrl-o which appears to do nothing (because Xen is waiting for the sysrq command that follows), so they do ctrl-o again which is taken as being command 'o' - immediate power off! I have had an emergency support ticket about this because "my guest randomly crashed while I was editing a file". I would therefore like to remap "magic sysrq" to something more obscure, or failing that disable it in guests as we/they will use "xl sysrq" instead. A couple of other things which may already be possible but I don't know how, so if anyone's done it maybe they could give hints: - Systematically and automatically log all guest console activity to individual files without interfering with the ability to use "xl console" - Somehow plumb the xenconsole pty to a web terminal like xterm.js Thanks! Andy
