Recently, I started exploring threats to Virtual machines in general. The first question that popped into my head was whether a host machine can dump its entire memory onto a file, and inspect the memory to read contents of the VM's memory image.
As virtualization essentially leads to the fact that the guest and host share the same RAM, I'm guessing that this is possible.
===================== | |VM| | =====================
Suppose the memory looks like this. 1GB memory for the VM out of a total of 8GB. So if I dump the RAM, I should be able to view contents of the VM RAM.
Q1. Is this a possibility? http://www.symantec.com/business/support/index?page=content&id=HOWTO31321 shows how to obtain a memory dump
Q2. Is this a threat? (I'm guessing no). However, if someone comes up with an idea, it would be splendid.
Q3. A more interesting scenario - Could the VM somehow grab the memory of the host? i.e. are there any known attacks on VMWare or other software that has documented such an attack ?
