The virtual machine Linux and the host are not on the same LAN

The virtual environment in the virtual machine will simulate a new network card in the real system, and this network card is the network card connected to the virtual machine network. That is, starting with the network, everything about virtual machines is virtual. So you will find that your Windows7 will appear with two IPs.

The virtual network of the virtual machine itself is not within a network structure, so there is information about why you should Google LAN yourself. So, if you look at the article on how dual network cards and dual LANs are interconnected, you will understand the problem.

If your physical LAN has a DHCP server, then you can try the bridging method, so that the vbox will let the virtual NIC run with your physical machine in the bridge server state, so that the virtual machine will be bridged to your physical machine's LAN with the help of the host bridge.

There are two ways to solve it, one is to use host-only+ics instead of nat.

Another way is to add a network card.

It depends on what mode you use.,It's all connected.,Check ubuntu's IP first.,That's it.。

Add another NIC to VBOX, use the host only mode, and then you can use the IP address of the block NIC to log in to SSH. Don't delete the NAT mode network card, otherwise the ubuntu inside won't be able to access the network.

Set the virtual machine to "bridge" mode, and set Windows 7 and Ubuntu to the same network segment.

If you really want to implement cross-network segment access.

Another virtual machine system can be used to simulate the route.

There is no need to reboot the machine when switching systems, and multiple operating systems are switched on the main platform, just like standard Windows applications such as Word Excel.

2.There is no difference between installing the operating system in the VMware virtual machine and installing the operating system on ordinary computers.,Yesterday I studied all night and finally figured out that the host and the virtual machine are connected to the Internet at the same time.,I use ADSL dial-up Internet access.。

3.In the default installation, VMware provides virtual NICs VMNet1 and VMNet8, as well as virtual NICs on the virtual system"amd pcnet family pci ethernet adapter\", vmnet1 and vmnet8 are virtual appliances on the main system, which can be seen with the ifconfig command"amd pcnet family pci ethernet adapter\"It is a virtual device on the virtual system, and you can see it in the device manager after installing the virtual system, the first two belong to the real system and are the devices in your real computer, and the latter one belongs to the virtual system and are the devices in the virtual computer.

4.NAT mode is selected for virtual machine access mode, and virtual NIC vmnet8 is used for virtual devices.

DHCP Assignment Range: Default.

5."Local Connection" in the network connection of the virtual machine is used"amd pcnet family pci ethernet adapter\"If the network is not connected, you can manually add the IP address (the last digit is greater than 2), the gateway address is, and the DNS can be set to the local DNS address, such as Timhe in Qingdao.

6.The virtual machine supports system snapshots, which can instantly backup and restore the system, and is completely isolated from the host system files, so that you will never be troubled by viruses and malicious programs again.
