Download, install VMware Open Virtualization Format Tool (and put it in your path variable)
https://communities.vmware.com/community/vmtn/server/vsphere/automationtools/ovf

Now you can convert the OVA in an OVF 
ovftool.exe --lax source.ova destination.ovf

Open the .OVF file in a text editor

change

<vssd:VirtualSystemType>virtualbox-2.2</vssd:VirtualSystemType>
to
<vssd:VirtualSystemType>vmx-07</vssd:VirtualSystemType>

change

<Item>
<rasd:Address>0</rasd:Address>
<rasd:Caption>sataController0</rasd:Caption>
<rasd:Description>SATA Controller</rasd:Description>
<rasd:ElementName>sataController0</rasd:ElementName>
<rasd:InstanceID>5</rasd:InstanceID>
<rasd:ResourceSubType>AHCI</rasd:ResourceSubType>
<rasd:ResourceType>20</rasd:ResourceType>
</Item>

to

<Item>
<rasd:Address>0</rasd:Address>
<rasd:Caption>SCSIController</rasd:Caption>
<rasd:Description>SCSI Controller</rasd:Description>
<rasd:ElementName>SCSIController</rasd:ElementName>
<rasd:InstanceID>5</rasd:InstanceID>
<rasd:ResourceSubType>lsilogic</rasd:ResourceSubType>
<rasd:ResourceType>6</rasd:ResourceType>
</Item>

Recalculate .OVF file SHA1 checksum (on Windows):
certUtil -hashfile destination.ovf SHA1

For linuxtou can use:
sha1sum destination.ovf

Open the .MF file and change the SHA1 checksum for the ovf file with the new value.

-------------------------------------------------------------------------------------

If on deploy, you get an error such as "Failed to deploy OVF package: The task was canceled by a user"
you must open the ovf file again and search for the line:

<rasd:ResourceSubType>vmware.cdrom.iso</rasd:ResourceSubType>

and change it to:

<rasd:ResourceSubType>vmware.cdrom.atapi</rasd:ResourceSubType>

After this you must recalculate de sha1 of the ovf file again.
