[PATCH] KVM-test: Add two scripts to disable services for perf tests

[PATCH] KVM-test: Add two scripts to disable services for perf tests

[Amos Kong]

System services on guest and host take uncertain resource, it effects
the perf results. We can use the below two scripts to disable some
services of host and guest.

stop_serivices_perf.sh is used to stop the running serivices.
off_service_perf.sh is used to off services when host starts up.

We can use them to prepare environment for performance testcases.

Which environment? I assume this should secured by an Distribution

specific guard:



E.g.



if [ -f /etc/redhat-release ] then

prepare clean testing environment.

yes.

Hi Amos, thanks! I've been thinking about those scripts, let me
summarize my thoughts:

 * If we are going to make this using scripts, then we should try as
much as possible to be distro agnostic.
 * We could detect services present on guest first before trying to
disable them, ie, instead of just issuing a service koan stop, verify
if there's a /etc/init.d/koan first.
 * Have you considered doing this env setup using shell commands typed
on an ssh session, such as

 session = vm.wait_for_login()
 session.cmd('service auditd stop')

Rather than a script? It's one less script to maintain under the
scripts/ directory.

 * Your approach is a blacklist of services that will be turned off.
What if we used a 'whitelist' approach and kept a list of the
fundamental services needed and turn off *everything else*?

Please let me know what you think about this. I'm not applying this for now.

We have a black list, if one server exist in the guest (/etc/init.d/*),
then stop it.

Some services need to be disabled by 'chkconfig * off', we can execute a python/shell
script in post installation, checking if service exists is also necessary.

Blacklist is safe and better, the whitelist is difficult to maintain.
