seeing a lot of such errors in the nightlies lately, where the test fails to run.

This seems to happen all the time, when someone accidentally tries to ssh to vpm machine from teuthology as user teuthworker, removing the conflicting entry resolves the issue.

We need to find a way to get rid of this.
