Configuring network in Red Hat Linux can be hectic and confusing if you don't know the parameter details which are used. Also from Red Hat 6 the configuration parameter has been changed for network-config. Let me show you out the steps to do the same along with some possible explanation.

This video tutorial shows Red Hat Enterprise Linux 7.4 (RHEL 7.4) installation on Oracle VirtualBox step by step. This tutorial is also helpful to install Re. For Oracle Linux or Red Hat Linux 6 (64 bits): VirtualBox-4.2-4.2.1686992el6-1. You create virtual network interfaces by defining a range of MAC addresses to use. Feb 28, 2010.

The configuration files used for complete network configuration in Red Hat 6 are
/etc/sysconfig/network-scripts/ifcfg-eth0 (can vary as per the NIC present)
/etc/nsswitch.conf
/etc/resolv.conf

Command Line configuration

Here below is a sample file configuration for ifcfg-eth0

# less /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
HWADDR=73:25:N4:2E:8C:46
TYPE=Ethernet
UUID=ca73df13-5553-4631-bfb4-9244f5e29190
ONBOOT=yes
NM_CONTROLLED=no
IPADDR=10.10.20.55
DNS1=8.8.8.8
GATEWAY=10.10.20.100
NETMASK=255.255.255.0
BOOTPROTO=none
USERCTL=no
PEERDNS=yes

• yes — This device should be activated at boot-time.
• no — This device should not be activated at boot-time.

where answer is one of the following:

• yes — NetworkManager is permitted to configure this device.This is the default behavior and can be omitted.
• no — NetworkManager is not permitted to configure this device.

• none — No boot-time protocol should be used.
• bootp — The BOOTP protocol should be used.
• dhcp — The DHCP protocol should be used.

where answer is one of the following:

• yes — Non-root users are allowed to control this device.
• no — Non-root users are not allowed to control this device.

• yes — Modify /etc/resolv.conf if the DNS directive is set. If using DHCP, then yes is the default.
• no— Do not modify /etc/resolv.conf.

In case you have used directive no for the parameter PEERDNS then you will have to manually update your resolv.conf file.

# vi /etc/resolv.conf
nameserver 8.8.8.8

Step 3:
Configure /etc/nsswitch.conf
#hosts: db files nisplus nis dns
hosts: files dns

GUI configuration

GUI configuration can be done either on command line as well as on the GNOME or KDE desktop.

Follow the screenshots (Click on the image for clear view)

Hit Enter on 'Device Configuration'

Select the device and hit Enter

Fill up the required details as shown below and click on OK

Once you click on OK you will reach on the first page of action. Select DNS Configuration and hit enter

Fill up the required details as shown below and hit Enter

Once you have filled up all detail move the cursor to Save and Quit and Hit Enter

Restart your network to make the change affect
# service network restart
or
# /etc/init.d/network restart

Because Oracle VM VirtualBox is designed to provide a generic virtualization environment for x86 systems, it can run guest operating systems (OSes) of any kind.

The following guest OS platforms are supported:

• Platforms With Full Support. These guest OS platforms qualify for Oracle Premier Support. See Table 3.1, 'Guest Operating Systems With Full Support'.

• Platforms With Limited Support. These legacy guest OS platforms can be used with Oracle VM VirtualBox, but only qualify for best effort support. Therefore, resolution of customer issues is not guaranteed. See Table 3.2, 'Legacy Guest Operating Systems With Limited Support'.

Oracle VM VirtualBox enables you to install and execute unmodified versions of Mac OS X guests on supported host hardware. Note that this feature is experimental and thus unsupported.

Oracle VM VirtualBox is the first product to provide the modern PC architecture expected by OS X without requiring any of the modifications used by competing virtualization solutions. For example, some competing solutions perform modifications to the Mac OS X install DVDs, such as a different boot loader and replaced files.

Be aware of the following important issues before you attempt to install a Mac OS X guest:

• Mac OS X is commercial, licensed software and contains both license and technical restrictions that limit its use to certain hardware and usage scenarios. You must understand and comply with these restrictions.

  In particular, Apple prohibits the installation of most versions of Mac OS X on non-Apple hardware.

  These license restrictions are also enforced on a technical level. Mac OS X verifies that it is running on Apple hardware. Most DVDs that accompany Apple hardware check for the exact model. These restrictions are not circumvented by Oracle VM VirtualBox and continue to apply.

• Only CPUs that are known and tested by Apple are supported. As a result, if your Intel CPU is newer than the Mac OS X build, or if you have a non-Intel CPU, you will likely encounter a panic during bootup with an 'Unsupported CPU' exception.

  Ensure that you use the Mac OS X DVD that comes with your Apple hardware.

• The Mac OS X installer expects the hard disk to be partitioned. So, the installer will not offer a partition selection to you. Before you can install the software successfully, start the Disk Utility from the Tools menu and partition the hard disk. Close the Disk Utility and proceed with the installation.

• In addition, Mac OS X support in Oracle VM VirtualBox is an experimental feature. See Known Limitations.

Be sure to enable I/O APIC for virtual machines that you intend to use in 64-bit mode. This is especially true for 64-bit Windows VMs. See Section 3.4.2, 'Advanced Tab'. For 64-bit Windows guests, ensure that the VM uses the Intel networking device because there is no 64-bit driver support for the AMD PCNet card. See Section 6.1, 'Virtual Networking Hardware'.

If you use the Create VM wizard of the VirtualBox Manager, Oracle VM VirtualBox automatically uses the correct settings for each selected 64-bit OS type. See Section 1.7, 'Creating Your First Virtual Machine'.
