novato-arc64-pre-cq runs on a machine that doesn't support KVM

Project Member Reported by norvez@chromium.org, Nov 30 2017

Issue description

The Pre-CQ for CL https://chrome-internal-review.googlesource.com/c/chromeos/overlays/overlay-novato-arc64-private/+/517512 fails:
https://luci-milo.appspot.com/buildbot/chromiumos.tryserver/pre_cq/70262

I think it's because it's running the VMTests on a machine where KVM is disabled, the log mentions:
"

"

novato and betty don't seem to have the same problem, even though as far as I can tell the configuration in chromite is the same. Is it possible to force novato-arc64-pre-cq to run on builders that support KVM?

I retried and this time the Pre-CQ passed:
https://luci-milo.appspot.com/buildbot/chromiumos.tryserver/pre_cq/70517

The job ran on a different bot which apparently supported KVM. Not sure which is which (GCE, baremetal, other?)
The failed build ran on "build16-m2" which is baremetal, though it's possible that the machine is misconfigured.

The retry ran on "cros-standard3-c2", which is a GCE instance which has KVM specially enabled.

Hum.... this is weird. I don't see that build in the history of build16-m2.
