Development Board-PC Machine (host)-network communication between virtual machines (VMS) How to set up and the problems needing attention

1. Do not use router switches

Hardware connection:
Connecting the Development Board to the PC using a network cable

Serial cable connects the PC and the Development Board

Use the command:

Ifconfig-a

Serial port control to view the network configuration of the Development Board

Route-n

Serial Console view gateway settings for the Development Board

If the Development Board:

ip:192.168.1.8

subnet_mask:255.255.248.0

PC corresponding configuration: (the same subnet can be)

ip:192.168.1.10

subnet_mask:255.255.248.0

The VM uses the corresponding configuration of the bridging mode: (same subnet is available)

ip:192.168.1.11

subnet_mask:255.255.248.0

2. Using the switch

Use two network cable to connect PC with switcher, development Board and Switcher, others are same as 1

3. Using Routers and switches

Hardware connection, connect the router (how to connect, looks like a lot of ways ah ...) ）

Set the respective default gateway as the IP address of the router, that is: 192.168.1.1, the remaining configuration is the same as in 2

Change the DNS address of the VM

sudo gedit/etc/resolv.conf

NameServer xxxx.xxxx.xxxx.xxxx (replace xxxx.xxxx.xxxx.xxxxwith a valid DNS address)

Note: Finally, sometimes you have to turn off the firewall
