Virtual Machine
built 279 days ago
A: The Virtual Machine is like another computer on the same network. If you have the Virtual Machine "VM1" running on top of the host "H1", it is like having two machines, VM1 and H1 on the same LAN. As such, any security violation that can be done between two machines on the same LAN can be done between VM1 and H1 (through networking protocols). From VMware's perspective, the memory and disk are completed isolated. One cannot get to read, and/or corrupt data on H1 through the VM1. If you decide to not have networking on VM1 (disable the Ethernet interface through the settings panel), it will be 100% isolated from the rest of the world (no network access to it).

One of the major Virtual Machine (VM) models in use today is the International Business Machines (IBM) view of virtual machines. IBM’s model is one in which each virtual machine is an exact copy of a real machine with a reduced memory capacity. With this notion, a large and powerful mainframe computer can be split up, or partitioned, into many virtual machines with slightly less resources available than the original mainframe computer.

Virtual Machine offers a unique “Timeline Control” that provides bi-directional review and playback of NC programs at any moment within the machining cycle. This unique function allows programmers to visualize and test NC post-processor for maximum output optimization.
