Hmm, it looks like the Hyper-V artifacts were built but they're not showing up in the stream metadata.

[bgilbert]

The hyperv artifacts didn't make it into the release metadata. Fix in coreos/coreos-assembler#3546.

[bgilbert]

From IRC discussion with @marmijo, we'll skip hyperv for this release, rather than trying to update release metadata for the existing builds.
