Bob Lantz 5dc15aeaaf Tolerate slow startup/lost pings for now 
In the long run we should troubleshoot the performance issue
on kvm/Ubuntu15, but for now we are relaxing the constraint.

Closes #593
 2016-01-26 15:40:56 -08:00
Bob Lantz 9a22e2b737 Use ifconfig for interface verification. 
Previously we were using both ip link and ifconfig - not only is
this inconsistent and redundant, but it also broke when newer
ip link changed the reported names of certain interfacs to
"h1-eth0@36:".

Fixes #592

Also clarified the code in test_simpleperf.py.

Bob Lantz 9ed14fa0f4 Remove explicit NAT code and use built-in NAT functionality. 
This API isn't great - we should try to improve it in the future.

We also clean things up a bit and check for error messages,
which now can cause exceptions which should invoke cleanup.

Bob Lantz bdad3e8c8e Merge OVSBatch into OVSSwitch 
Note that we are changing the interface of batchStartup/Shutdown
slightly so that the method can choose not to start some of the
switches. We might wish to refine this a bit...

Bob Lantz c1b48fb5c8 Stub out RemoteOVSSwitch.batchShutdown() 
Eventually we should implement true batch shutdown.
In the mean time, we just ignore it. Note there's no good
way that I know of for a subclass to remove a superclass
method, so we changed the protocol a bit to require a return
value of True.
