Request: Serial Terminal logging

[riptide_wave]

Hello,

Recently I have been having issues with one of my VM instances locking up, and am having a hard time diagnosing the cause. Currently the plan is to just run "qm terminal 1**" in a screen session, but this is not the best way as it does not persist across reboots of the hypervisor.

With that said, is there any way to enable logging of a VM that has serial enabled? It would be great to have it log console output to a file, for example, /var/lib/vm-serial/1**.log. This way logrotate could be added to help prevent obsessive disk usage.

This would be a great feature, though such logs probably belong in /var/log rather than /var/lib.

I use linux kernel internal features which are normally also used on "real" hardware for this:

• netconsole for "remote logging"
• sysrq and crashkernel for direct logging and crashing

Derp, this is what I meant. Guess the 2AM sleepiness got to me.
