Re: [Lxc-users] getting output from lxc-start?
Oh cool, I didn't know about lxc.console. I just tested it now, and it looks like it worked.

You can direct it to a file in your .conf: lxc.console = /var/log/lxc/foo.console If that output doesn't resemble native booting, it might simply be that you aren't seeing output from the kernel, udev, mount -a/mountall, &c -- because those systems don't run in the container. Ubuntu, at least, does not log very much to /dev/console by default. In particular, it emits output for sysvinit jobs (e.g. slapd, apache2), but not upstart jobs (e.g. rsyslog, ssh, squid). Or if your container isn't working, that could be the cause :-) -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!

Is the log output the same as the console output? The last time I looked, the information in the debug logs looked different compared to the boot logs. I'll check out rc1.

[Lxc-users] getting output from lxc-start?
Hi, I've been messing around with trying to get the output of lxc-start into a file some. I know that lxc-start produces a log file, as well as the ability to fetch the dmesg file directly from the container's log file directory, but I was curious if it was possible to just run lxc-start in a nohup and use some kind of dummy getty instance to pipe the output into a file. The closest thing I could find was using screen's logging capability. The log file produced by lxc-start doesn't really resemble the output generated from the container boot. Is there dummy getty/terminal thing that I could get the actual output of the container boot process? Thanks, Dean -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
