- Login to the host where the virtual machine lies and try and do a snapshot via here instead of VCentre
- If Take Snapshot is greyed out on the host , then check the settings of the device for :
- Does it have an PCI Devices cards mapped to it? E.g. for Use of Tape Drives. If so these will need to be removed as Vmware doesn’t support snapshotting these.
- Does it have any physical mapped Drives to it instead of virtual , again is not supported for snapshotting
- Try shutting down the VM to see if you can snapshot it shutdown insteaf of powered off
