I have compiled EMANE and run the first two demonstrations on OpenSUSE
12.3 (x86_64).
uname -a
Linux jib 3.7.10-1.16-desktop #1 SMP PREEMPT Fri May 31 20:21:23 UTC 2013
(97c14ba) x86_64 x86_64 x86_64 GNU/Linux
Some of the problems that were encountered are:
1) scripts/lxc-demo-stop.sh is missing a getopts parameter.
2) scripts/lxc-demo-start.sh, and the scripts it calls, uses
lxc-execute to set up the containers. It then uses lxc-ls
to check if the containers have been set up.
In the versions of lxc I've tried (0.8.0 and 0.9.0),
the bookeeping enteries used by lxc-ls are set by
lxc-create. They are not set when lxc-execute is used
to build the containers. Thus, lxc-ls fails.
3) I ran emane su'd to root. The initial PATH didn't include
the right directories and/or I created confusion by installing
under "/usr/local". The upshot was that I had to explicitly
point to the locations of some of the executables used
in the scripts, and/or change certain configuration parameters.
For example, the file "scripts/funcitons" has a reference to
"route" hard-coded into it. I had to change that to "/sbin/route",
otherwise the pipe containing "route" fails.
In another file, I changed "olsrd" to "/usr/local/sbin/olsrd".
4) In order to run with the realtime option, I had to set a value into:
/sys/fs/cgroup/cpu,cpuacct/lxc/cpu.rt_runtime_us
which is greater than (or equal to?) the sum of the values that the
demonstration scripts place in:
/sys/fs/cgroup/cpu,cpuacct/lxc/node-*/cpu.rt_runtime_us
Perhaps earlier Linux kernels didn't enforce this constraint?
Upon request, I can provide further details on the hair-pulling and
workarounds I employed.
