How does once check for the presence of a VM from inside the VM? Doesn't that defeat the purpose of the VM to begin with?
- lifthrasiir 7y agoTheoretically speaking you can make a VM that is indistinguishable to a real computer. In reality most VM solutions do not attempt to do so. For example, many install specialized drivers to communicate to the host that can be readily checked.

If it's about separating mostly trusted applications and/or servers, then absolutely not. If it's about investigating known-bad code, then, yes, absolutely - malware is often intentionally disabling itself when it detects it's running in a VM.
