Right-click the first vSphere Cluster Services virtual machine and select Guest OS > Shut down. That datastore was probably selected based on the vSphere algorithm for checking the volume with more free space available and more paths to different hosts. Both from which the EAM recovers the agent VM automatically. log shows warning and error: WARN c. The vCLS agent virtual machines (vCLS VMs) are created when you add hosts to clusters. The API does not support adding a host to a cluster with dead hosts or removing dead hosts from a cluster. The Agent Manager creates the VMs automatically, or re-creates/powers-on the VMs when users try to power-off or delete the VMs. These services are used for DRS and HA in case vCenter which manages the cluster goes down. MSP is a managed platform based on Kubernetes for managing containerized services running on PC. flag Report. What I want is all VMs that are in a specific cluster AND a specific folder, but attempting any combination of the above throws errors. n. vCenter thinks it is clever and decides what storage to place them on.
