To know more about it see Wikipedia page on it. The VMBus is a logical channel which enables inter-partition communication. In this way, whatever, VM we are running on this type -1 hypervisors access the hardware via VMBus partition. Now, what is the reason, why we couldn’t run earlier them together? It is because the HyperV is a Type- 1 hypervisor while VMware Workstation is Type 2 which runs on the OS, here Windows 10, whereas Hyper-V itself an OS, thus it converts and uses whole Windows 10 host as a Virtual Machine. But now it is, now we can run WSL2 (Windows subsystem for Linux) or Hyper-V along with VMWare workstation Pro 20H1.

However, it was not possible earlier these two to run at once on a single machine, we have to turn off Hyper-v, first to get the Workstation of Vmware working. It has been a very long time people are looking for a way to run Vmware Workstation and Hyper-V together on the same Windows 10 machine.
