Hi Jason,
this bug is already fixed in the latest builds.
I was able to successfully install the hosted engine with the following
rpms installed.
1. Install and enable the preview repo as described here:
http://www.ovirt.org/OVirt_3.4_Test_Day
and then install the following packages:
http://jenkins.ovirt.org/view/Packaging/job/ovirt-hosted-engine-ha_create_rpms/label=fedora19/lastSuccessfulBuild/artifact/exported-artifacts/ovirt-hosted-engine-ha-1.2.0-0.0.master.20140324152134.20140324.git24efa6a.fc19.noarch.rpm
http://jenkins.ovirt.org/view/Packaging/job/ovirt-hosted-engine-setup_create_rpms/label=fedora19/lastSuccessfulBuild/artifact/exported-artifacts/ovirt-hosted-engine-setup-1.2.0-0.0.master.20140324112909.gitc0e9c96.fc19.noarch.rpm
