Given the task definition and input, reply with output. Craft one correct answer to the question given in input. To make it more interesting, try to use non-stereotypical language if possible. Make sure your correct answer is reasonably long, consistent with the context, and requires common sense (instead of explicit extraction from the context.) In your answer, use as few words as possible from the given context. Use a response that is uncommon/non-stereotypical, so that it is less predictable. To be less repetitive, please vary your language for each question.

Context: We recently set up a generic test Win 2K8 guest instance on an ESX server . The client was given 12 GB ram ( the host has 26 ) . In the VM , in windows task manager it claims it 's using 1.75 GB ram . On the ESX server , it 's claiming this VM is taking up 7.7 GB of host RAM however ( compared to the 10 or so Win 2K3 instances that are only about 1 GB ) .
Question: What may be the reason why they are getting different readings ?
Because they are on different servers .
