VM-VM Anti-Affinity rules in DRS direct VMs to not run on the same host. A Resource Pool with a high share value does not prevent co-location, and Storage vMotion or HA Admission Control do not specifically separate VMs across hosts at runtime.

vMotion enables live migration of a powered-on virtual machine from one ESXi host to another without service interruption.

When users are unable to access the vCenter Server and the vSphere Client is not responding, the first step is to check if the vCenter Server is powered on and whether its essential services are running. This can include services like the vCenter Server service, vSphere Web Client service, and other related services that enable access to the vCenter Server. If the services are stopped or unresponsive, restarting them may resolve the issue.

Comprehensive and Detailed Explanation From Exact Extract:
According to the VMware vSphere with Tanzu Documentation and VMware Cloud Foundation 5.2 Administration Guide, the supported method to access Supervisor Control Plane VMs for troubleshooting involves the following actions:
Option B: Log into the Supervisor Control Plane VM using the admin user and <password>.
Exact Extract from official documentation:
"To troubleshoot Supervisor Control Plane VMs, log in via SSH using the 'admin' user and the password specific to the Supervisor Control Plane VM." (VMware vSphere with Tanzu Documentation - Supervisor Control Plane VM Access) Option E: Update the <password> by running /usr/lib/vmware/auth/bin/chpw admin.
Exact Extract from official documentation:
"If you need to update the 'admin' password for Supervisor Control Plane VMs, use the command
'/usr/lib/vmware/auth/bin/chpw admin' on the VM."
(VMware vSphere with Tanzu Documentation - Changing Admin Passwords)
Option F: Obtain the <password> by running /usr/lib/vmware-wcp/decryptK8Pwd.py.
Exact Extract from official documentation:
"You can retrieve the 'admin' password for the Supervisor Control Plane VM by running the Python script
'/usr/lib/vmware-wcp/decryptK8Pwd.py' on the vCenter Server Appliance." (VMware vSphere with Tanzu Documentation - Retrieving Admin Credentials) Why Not the Other Options?
Option A: Logging into the vCenter Server Appliance is not necessary for direct access to the Supervisor Control Plane VMs.
Option C: SDDC Manager appliance access is unrelated to Supervisor VM troubleshooting.
Option D: Root login to Supervisor Control Plane VMs is not supported or documented for troubleshooting.
Summary:
To access the Supervisor Control Plane VMs for troubleshooting, the administrator must use the admin user and password (B), can update the password using the chpw command (E), and retrieve the current password using the decryptK8Pwd.py script (F), following the exact steps documented in the VMware official guides.
