Hi Serge,
Thank you for your question, it point me to the core!
I thought it was a lxc internal problem, but it was caused *completely* by my
own. I have copied a snippet from other lxc scripts to deal with the old and
new cgroup style to a container. And unlike all other usage, in the start
script I did a evaluation of this before a container is running. And for before
the first start, there is no lxc directory even with the newer lxc. :o
>From a construct like
CGROUPPATH="/cgroup" # our default
[ -d "$CGROUPPATH/lxc" ] && CGROUPPATH+="/lxc" # for newer lxc
and using the option
-s lxc.mount.entry=$CGROUPPATH/$CONTAINER cgroup none ro,bind 0 0
for lxc-start, the script have calculated a wrong dynamic mount for the
containers cgroup view. I use this to support some tools like a lxc-aware
replacement for 'free'.
I just have to setup a better test based on lxc-version, i.e.
REQUIRELXCVERSION () { # $1: Version
[[ ! "`lxc-version | sed 's#.*: ##g'`" < "$1" ]] # i.e. >=
}
REQUIRELXCVERSION 0.8 && CGROUPPATH+="/lxc" # for newer lxc
Sorry to all
Guido
