Configuring Fedora 18 to run VDSM functional tests

[Zhou Zheng Sheng]

Thanks Fabian. I have a look at igor. It's very powerful. From what I 
understand, Jenkins invokes igor client to upload the test plan to 
igord. igord starts VMs and let cobller setup the guest OS, then the 
igor guest agent inside guest OS download the test from igord and run 
them. The igor guest agent will upload the test result after each test 
step. The communication is through HTTP. igord implements a REST-like 
web interface. Extra parameters can be passed to the guest agent by 
appending the kernel arguments of the guest OS.

If I want to setup several VMs and run a cluster test plan on them, igor 
will be very helpful. I think igor is a little too heavy for the current 
VDSM functional tests. For now we just run the tests on single node. I 
think it's easier to do this using the libvirt-slave plugin for Jenkins. 
It enables Jenkins start VM as a slave and shutdown after use. The slave 
can be put behind the NAT using the default libvirt network. I have 
already configured this environment and test it in my lab. It seems good 
enough for this task.

We have some proposals for a cluster test plan in our team. I will learn 
more about igor and see if we can leverage it. It will be very useful if 
igor is integrated to the oVirt infrastructure. We can re-use this 
service to more high level tests.
