Assume "A" is a target network on the internet running some windows servers using "XEN" virtualization and some linux servers inside vmware workstations,
Now assume i am on some random network on the internet,with different ISP ,I need to detect or confirm whether the target servers with any kind of "virtulaization" technology,
Also is there any difference between a OS running inside a "virtual environment" and "non-virtual environment"?with what kind of characters i can identify this?
As my target network is located behind router,I am struggling to determine this,..Looking for some ideas
2)I am much more interested in Practicing enumeration on a NAT network,
but considering legal issues ,I don't know where to practice this enumeration,Also i don't know where to find a NAT network for practicing,Can any body give some suggestions for this problem?
Hope i will find some help...
