Moving Fusion VMs to ESXi

Moving Fusion VMs to ESXi

I am in the process of moving several VMs created in VMWare Fusion 5 into
ESXi 5.1, which I just installed on a Mac Mini Server. I am able to
connect just fine via the Windows application installed on another VM. I
have created two OVF files, one for Server 2003 and another for Server
2012. Both files were created without incident. I am able to upload them
to the ESXi server seemingly without issue as well.
However, when I start either of the VMs, I get the following error(s):
Console:

And in the GUI:

I'm unsure how to proceed, as I have followed the steps outlined to create
an OVF file and upload it to the ESX. Both of these VMs work fine through
Fusion.
Thanks in advance.
