kvm autotest, how to disable address cache

kvm autotest, how to disable address cache

[Ryan Harper]

Is there any way to disable this?  I'm running a guest on -net user
networking, no interaction with the host network, yet, during the test,
I get tons of:

15:50:48 DEBUG| (address cache) Adding cache entry: 00:1a:64:39:04:91 ---> 10.0.253.16
15:50:49 DEBUG| (address cache) Adding cache entry: e4:1f:13:2c:e5:04 ---> 10.0.253.132

many times for the same mapping.  If I'm not using tap networking on a
public bridge, what's this address cache doing for me? And, how the heck
do turn this off?

Currently that's not configurable.  It's there under the assumption that
it doesn't annoy anyone too much.  Now that I know you're annoyed by it
I'll send a patch to make it optional.  If you can't wait, feel free to
comment out the first paragraph in kvm_preprocessing.preprocess().
