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.

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.
