IPv6 address incorrectly required with EUI-64 when mac is provided by compute resource
When creating a host with IPv6 in an EUI64 enabled subnet, a user cannot save the VM because Foreman requires an IPv6 address for the host. The address should be auto generated based on the mac address. The mac address is provided by the compute resource. So the VM has to be saved first. When the mac is known from the compute resource, the ipv6 address can be generated.
