VMware, Workstation Foundation

I believe that we have used VMware Workstation this software, but many times do not know the Workstation lurking many features, spend a few days to learn the system under the use of this software.

Introduction of virtualization Technology and solutions

1. Mainstream virtualization manufacturers and their products

Mainstream manufacturers	Virtual Server	Virtual Desktops	Virtual applications

Global management and allocation of computer resources

Ability to create and manage virtual networks

Managing Virtual Machines

2 , the impact of Workstation installation on our system

VMware Workstation Software Installation process There's nothing to say, let's see what the impact of Workstation on our system after installation is complete.

There are two main aspects of the impact: Services and networks

1) Service

Open the Services interface to see:

Authorization Service provides authentication and authorization for remote users to access local shared virtual machines

DHCP Service dedicated to virtual network IP assignment

NAT Service dedicated to virtual network IP address translation

USB Arbitration Service USB quorum services, USB devices used on virtual machines or physical machines

Workstation Server registers and manages the remote Access Service, which is the ability to share on-premises virtual machines

2) Network

Open a network connection to see two more virtual network cards

These 2 network cards, which are virtual by workstation software, are the bridge between physical and virtual machine communication.

Workstation three ways to connect virtual machines:

Bridging mode (bridged):

The VMware Bridege Protocol protocol is added to the physical machine's real network card

in bridging mode, VMware simulates a virtual network card to the customer system, which is equivalent to a bridge for the customer system. The customer system seems to have its own network card, directly connected to the Internet, which means that the customer system is visible to the external direct connection.

Simply put, the virtual host and the physical host in the same network segment, the equivalent of a LAN more than a computer in the Internet, and this computer is a virtual machine system. The IP of the physical host and the virtual host is in the same network segment, the DNS and gateway are the same , so that the physical host and virtual host, virtual host and the external network communicate with each other.

Network Address translation mode ( NAT ):

Requires VMnet8 NIC

in this way, the client system cannot connect to the network itself, but must address the data packets sent and received by all the client systems in and out of the network through the main system. In this way, the customer system is not visible to the outside.

The virtual network card in the physical host, VMware NetworkAdapter VMnet8, is the equivalent of a network card connected to the intranet, while the virtual machine itself is equivalent to the machine running on the network, the physical network card equivalent to the network card connected to the external network. in this way, VMware's own DHCP is loaded onto the VMNET8 by default so that the virtual host can use the DHCP service. More importantly, VMware comes with a NAT service that provides address translation from Vmnet8 to extranet (physical NIC), so this is a real NAT server running, except that NAT is for virtual machines.

Note: In this way, the virtual machine can access the Internet as long as the host is able to access the Internet, but the host and the Internet cannot access the virtual machine.

host-only Network mode:

requires VMnet1 Nic         

The only difference with NAT is that, in this way, there is no address translation service, so by default the virtual machine can only access the physical machine and not the Internet, which is also the meaning of Hostonly's name.
