Pkg xen devel - Mar 2009 - Bug#517863: Make logging of guest console output in dom0 via xenconsoled configurable

Package: xen-utils-3.2-1
Version: 3.2.1-2
Severity: wishlist

Hi,

this morning I spend some time to find out how to log console output of 
Xen guest domains into a file in dom0.

I ended up using a quick 'n dirty solution:

mario:/usr/lib/xen-3.2-1/bin 0-# diff -u xend.orig xend
--- xend.orig	2009-03-02 16:49:49.000000000 +0100
+++ xend	2009-03-02 16:16:03.000000000 +0100
@@ -100,7 +100,8 @@
      import time
      time.sleep(2)
      if os.fork() == 0:
-        execute('xenconsoled')
+        args = ["--log", "guest", "--log-dir",
"/var/log/xen/guest/"]
+        execute('xenconsoled', args)

  def start_blktapctrl():
      if os.fork() == 0:
mario:/usr/lib/xen-3.2-1/bin 0-#

It seems the options used to start xenconsoled cannot be configured in 
Debian now. /etc/init.d/xend executes /usr/lib/xen-3.2-1/bin/xend which 
executes xenconsoled subsequently.

Hi Josip,

thanks for the information and closing this wishlist-item. The 
XENCONSOLED_ARGS= is exactly what I was looking for.

I don't think logging should be enabled by default, as it could 
potentially be a way for misbehaving guests to unexpectedly fill up your 
hypervisors disk space.

But I think xenconsoled should have a manual page to document the 
options which can be used. Running /usr/lib/xen-4.0/bin/xenconsoled 
--help does list the options, but does not explain them.

It would probably be nice to include some documentation in 
/usr/share/doc/xen-utils-4.0/README.Debian about this, the logrotate 
example could be included there as well.

I'll open a new bug against xen-utils-4.0, providing some documentation 
that could be included in README.Debian.
