After renaming and splitting RPMs in v2v-conversion-host we now require v2v-conversion-host-wrapper RPM to be available on hosts. That also includes ovirt-host.
Verified in ovirt-host-4.3.2-1.el7ev.x86_64 ovirt-host-dependencies now requires v2v-conversion-host-wrapper: # rpm -qR ovirt-host-dependencies | grep v2v v2v-conversion-host-wrapper
