I see. The failures really stopped after I rebased to that
commit.

I saw a failure on x86-pull-request that seemed to be because of
vhost-user-test[1]. However, after restarting the job, it
passed[2]. (I can't confirm the actual cause of the first
failure, because the log files seem to be temporarily unavailable
on Travis.)

Now, the problem with vhost-user-test is that it is not
guaranteed to work without KVM[3], so we need to add a mechanism
to skip vhost-user-test (or at least make errors non-fatal) if
KVM is unavailable.
