Questions regarding virtualized SAP B1 / HANA install

Hi,

I want to install SAP B1 9.3 on VMWARE VSphere 6.5.

One virtual machine should have only the HANA DB and the other one only the SAP Business Components, if possible.

The HANA DB used in a combo with SAP B1 can only be installed under SLES (for support reasons). To realize this goal I would need to 2 SUSE virtual machines. My physical server has 128 GB and 3.8 TB disk space.
I am currently studying documentation but there are several points that still not clear to me.

I looked at:
https://blogs.sap.com/2014/09/10/sap-business-one-version-for-sap-hana-on-vmware-vsphere-guide/

Furthermore the following 2 notes caught my eye:
2020657 - SAP HANA SPS 05, SAP supports the virtualization of SAP HANA with VMware vSphere 5.1 for non-production scenarios on either certified appliances or through SAP HANA tailored data center integration verified hardware configurations.
SAP extends support for SAP Business One, version for SAP HANA on VMware to the same degree as generally applicable for SAP HANA on VMware.

Does note 2393917 apply? It states:
SAP extends support for SAP HANA on VMware vSphere 6.5, providing the following conditions are met:
SAP HANA start release: SAP HANA 1.0 SPS 12
Single and multiple SAP HANA production virtual machines on a single physical server
CPU Architecture: Intel Broadwell E5 EP - 2-socket / E7 EX 2 & 4 & 8 socket
The minimum size of a virtual SAP HANA instance is a half socket (represented by at least 8 physical cores). The minimum is 128GB of RAM

Now this results in several questions for me:

1. Using VSphere is the installation of several Virtual machines (1 x HANA DB, 1x SAP Business One Components, etc.) on the same VSphere Host is supported by SAP?
2. If this is supported, does the VM for SAP HANA need to get 128GB of RAM when using VSphere 6.5? If I use a lower version of VSphere is the memory required less (and would it still allow me to install other VMs beside the one for HANA)?
3. The 128 GB needed for HANA do not include the components for SAP Business One? How much RAM is needed if I install those Components in the same VM as HANA, more than 128GB?
How much RAM does a separate VM containing only SAP Business Components require?
4. HANA is sold in units of 64GB, does this apply for the combo with SAP Business One as well? Or is there a different license model?

Best regards,

Nils
