Any VM runs on physical hardware that will have Ethernet hardware, and ALL Ethernet hardware at its PHY layer each has a unique ID. That means the VM and any other OS on the machine all have to talk to the same IDed hardware regardless. So a VM does not buy you true anonymity. Plus, any tool that can find a way to query the machine's BIOS can get the unique MAC address and then you're identifiable. The MAC address cannot be changed, it is permanent. Also, packets contain that unique ID; with a VPN, the provider does know your MAC address, so a corrupt provider can give info on you if an agency demands it.
