‌There is an advanced setting you can set to allow this. See William Lam's post for more info:

‌What's unclear?

You need to go into the advanced settings of the vCenter Server you are enabling HA on and change the advanced setting as referenced in William's post.

Cheers, Matt.

You can run it all on a single host but it is unsupported. A minimum of 3 hosts is required. If this was for production, running all 3 nodes on a single host would defeat the purpose of an HA solution. But, if this is just to test it in a lab environment Willam's post shows you how to do it with limited resources.

Hi ,

VCHA Basic configuration setup and Advanced configuration setup both can be configure with only 1 host,but it defeat the purpose of  having HA for VC.

Hello,

For your lab purpose you can use one ESXi host to configure VCHA to edit HA advanced settings, but in production configuring VCHA required minimum 3 ESXi hosts. Because VCHA configuration will install additional 2 nodes called Passive & Witness. So, the scenario here is deploy all nodes in to different ESXi hosts/storage.
