How do I modify the base image file for the VM-1000-HV license?

Open the base image file, for example 7.0.0, with a text editing tool such as notepad.
Search for 4096 and change the memory allocated to 5012 (that is 5 GB) as follows:
<Item> 
        <rasd:AllocationUnits>byte * 2^20</rasd:AllocationUnits> 
        <rasd:Description>Memory Size</rasd:Description> 
        <rasd:ElementName>4096MB of memory</rasd:ElementName> 
        <rasd:InstanceID>2</rasd:InstanceID> 
        <rasd:ResourceType>4</rasd:ResourceType> 
        <rasd:VirtualQuantity>
4096</rasd:VirtualQuantity> 
<Item> 
        <rasd:AllocationUnits>byte * 2^20</rasd:AllocationUnits> 
        <rasd:Description>Memory Size</rasd:Description> 
        <rasd:ElementName>5120MB of memory</rasd:ElementName> 
        <rasd:InstanceID>2</rasd:InstanceID> 
        <rasd:ResourceType>5</rasd:ResourceType> 
        <rasd:VirtualQuantity>
5120</rasd:VirtualQuantity> 
Change the number of virtual CPU cores allotted from 2 to 4 or 8 as desired for your deployment:
<Item> 
        <rasd:AllocationUnits>hertz * 10^6</rasd:AllocationUnits> 
        <rasd:Description>Number of Virtual CPUs</rasd:Description> 
        <rasd:ElementName>2 virtual CPU(s)</rasd:ElementName> 
        <rasd:InstanceID>1</rasd:InstanceID> 
        <rasd:ResourceType>3</rasd:ResourceType> 
        <rasd:VirtualQuantity>
2</rasd:VirtualQuantity> 
        <vmw:CoresPerSocket ova:required="false">2</vmw:CoresPerSocket> 
      </Item> 
<Item> 
        <rasd:AllocationUnits>hertz * 10^6</rasd:AllocationUnits> 
        <rasd:Description>Number of Virtual CPUs</rasd:Description> 
        <rasd:ElementName>4 virtual CPU(s)</rasd:ElementName> 
        <rasd:InstanceID>1</rasd:InstanceID> 
        <rasd:ResourceType>3</rasd:ResourceType> 
        <rasd:VirtualQuantity>
4</rasd:VirtualQuantity> 
        <vmw:CoresPerSocket ova:required="false">2</vmw:CoresPerSocket> 
      </Item> 
Alternatively, you can deploy the firewall, and before you power on the VM-Series firewall, edit the memory and virtual CPU allocation directly on the ESXi host or the vCenter server.
