I would recommend spreading them around. vCLS VMs are by default deployed with a " per VM EVC " mode that expects the CPU to provide the flag cpuid. Cluster was placed in "retreat" mode, all vCLS remains deleted from the VSAN storage. 7 so cannot test whether this works at the moment. Back then you needed to configure an advanced setting for a cluster if you wanted to delete the VMs for whatever reason. When you create a custom datastore configuration of vCLS VMs by using VMware Aria Automation Orchestrator, former VMware vRealize Orchestrator, or PowerCLI, for example set a list of allowed datastores for such VMS, you might see redeployment of such VMs on regular intervals, for example each 15 minutes. To re-register a virtual machine, navigate to the VM’s location in the Datastore Browser and re-add the VM to inventory. Unable to create vCLs VM on vCenter Server. vCLS uses agent virtual machines to maintain cluster services health. But honestly not 100% certain if checking for VMware Tools has the same underlying reason to fail, or if it's something else. Runtime.
