harbor: Deploying harbor with ovftool gives memory error

When I use ovftool to deploy the respin2 version of the harbor ovf, I get the following error:

 - Virtual machine has 4,096 megabytes of memory, which is outside the range of 4 to 3,600 megabytes supported on the host. This may be a general limitation of the host software, or specific to the guest OS selected for the virtual machine.
Completed with errors

When I look at harbor installed with a Windows vsphere client (thick client), the VM indicates it’s using hardware version 4 (esx 3.5). When I look in the harbor ovf file, there is no specification for hardware version. I wonder if this is causing the problem.

I used ovftool 4.1.0, build 2459827 for Linux.
