Hello,
I have done a small utility to build containers
using kernel API 'clone' available with kernel-2.6.31.
So far I am able to run more than 30 different
distribution (from rh7.3 -> fc12) on the same
host.
(ftp://ftp.safe.ca/pub/linux/vzgot to know more.)
Everything is working fine...
Except seems HOST and all containers share the
SAME /proc/kmsg, meaning kernel syslog information
are scrambled (useless).
Namely, I have in iptables, reject packet logging
on the HOST, as soon rsyslog is started on one
container, I can't see my reject packet log anymore.
Also, container have their own iptables with reject
packet logging which are not displayed too.
Am I wrong/forgetting something about the /proc/kmsg
sharing?
If I am right, should ALL /proc/kmsg be isolated from
each other???
How could it be done??

A bientôt
