Hi Uri/Lucas,
Do you have any plans for enhancing kvm-autotest?
I was looking mainly on the following 2 aspects:
(1).
we have standalone migration only. Is there any plans of enhancing
kvm-autotest so that we can trigger migration while a workload is
running?
Something like this:
Start a workload(may be n instances of it).
let the test execute for some time.
Trigger migration.
Log into the target.
Check if the migration is succesful
Check if the test results are consistent.
We have some patches of ping pong migration and workload adding. The
migration is based on public bridge and workload adding is based on
running benchmark in the background of guest.
(2).
How can we run N parallel instances of a test? Will the current
configuration be easily able to support it?
Please provide your thoughts on the above features.
The parallelized instances could be easily achieved through
job.parallel() of autotest framework, and that is what we have used in
our tests. We have make some helper routines such as get_free_port to be
reentrant through file lock.
We've implemented following test cases: timedrift(already sent here),
savevm/loadvm, suspend/resume, jumboframe, migration between two
machines and others. We will sent it here for review in the following weeks.
There are some other things could be improved:
1) Current kvm_test.cfg.sample/kvm_test.cfg is transparent to autotest
server UI. This would make it hard to configure the tests in the server
side. During our test, we have merged it into control and make it could
be configured by "editing control file" function of autotest server side
web UI.
2) Public bridge support: I've sent a patch(TAP network support in
kvm-autotest), this patch needs external DHCP server and requires nmap
support. I don't know whether the method of original kvm_runtes_old(DHCP
server of private bridge) is preferable.
