Oracle Virtual Box VM:-How to create network setting and interface in Oracle Virtual Box to connect internet as well as connect from host

This note will describe the process to connect Oracle Virtual box VM directly from your host using ssh as well as from VM to internet connection.

I will use 2 types of VM interface.

a)NAT network for internet connection from VM

b)Host only adapter for ssh connection from host to the VM.

Step 1:-First I will go to File->Preferences and check/create NAT network with below settings in Oracle Virtual box :-

Step 2:-Create host-only network as well

DHCP server should not be enable here

Step 3:-Please create first network interface (NAT)

Step 4:-Please create host-only adapter interface

step 5:-Please check persistent rules under /etc/udev/rules.d and modify mac address if possible.The MC address should be same which was visible in step 3 and step 4

Step 6:-Please create ifcfg-eth1 and ifcfg-eth2 using below settings.ETH1 is for NAT and ETH2 is for host-only adapter.Please check HWADDR value as MAC address in previous steps.

Step 7:-Now reboot your VM or restart individual Network interface (eth1 and eth2) using ifup or ifdown command.

Step 8:-Please check ifconfig -a

step 9:-Please enable root login

enable  PermitRootLogin to yes in  /etc/ssh/sshd_config.

[root@rac1 yum.repos.d]# service sshd restart

Redirecting to /bin/systemctl restart sshd.service

Step 10:-Now you can check whether you connect to host using IP 169.254.156.100.You can also check ping to google.com after login to VM
