Need help finding an owner for this test.

This is the entry point for all VMTest tests. From the logs it looks like the builder was not able to connect to the KVM instance. I don't know if there are more logs but you could run the failed command locally and see if it's reproducible. Also, adding Aviv who might know the better person to ask for help.

Yes, as wonderfly@ said, the machine has problem connecting to its KVM instance.
It reminds me of a past issue crbug.com/808045 that it has network ip address collision once builder to GCE instance. Maybe it is related, but at current stage, we should run the failed command locally and check if it's reproducible.
