Re: [Xen-devel] Questions about LOG system

[ææå <Chunqi Li> <yzt356@xxxxxxxxx>]

Well, I have found the wrong code.

The macro DPRINTFÂ points to

#define DPRINTF(_f, _a...) xc_report(xch, xch->error_handler, XTL_DETAIL, 0, _f, ## -a)

So is this Xen's private log system ? Where messages write via xc_report and xc_report_error function?

Thank you.

Syslog is a standard Unix function (SUSv2 and/or POSIX IIRC) and not
something specific to Xen. Google or "man -k" should be able to find you
more details of this and related functions.

The final location will depend somewhat on your distro's configuration,
it's likely to be somewhere under /var/log. A distro specific list or
forum would be a more appropriate place to pursue this.
