Environment

ESXi 7.x, ESXi 8.x

Cause

The virtual machine shutdown process overlapped with another management operation specifically, a resource reconfiguration triggered by host synchronization. This conflict can also occur during other operations such as snapshot creation or modification. Due to the simultaneous tasks, the VM may not restart automatically after shutdown.

Resolution

Engineering Team is aware of this issue and will be fixed in future release.
