You can use vmware-cmd to revert to the current snapshot or to remove a snapshot.

Important: You cannot use vmware-cmd to revert to a named snapshot. Use the vSphere Web Client to revert to a named snapshot.

Run vmware-cmd with the revertsnapshot option to revert to the current snapshot. If no snapshot exists, the command does nothing and leaves the virtual machine state unchanged.

vmware-cmd -H <vc_system> -U <user> -P <password> --vihost <esx_host> /vmfs/volumes/Storage2/testvm/testvm.vmx revertsnapshot

Run vmware-cmd with the removesnapshots option to remove all snapshots associated with a virtual machine. If no snapshot exists, the command does nothing.

vmware-cmd -H <vc_system> -U <user> -P <password> --vihost <esx_host> /vmfs/volumes/Storage2/testvm/testvm.vmx removesnapshots
