How To Add Together Novel Network Adapter Inward Hyper-V Linux Centos 6.4

This is the blog, how to add together novel network interface inwards Hyper - V Centos 6.4 Virtual Machine.

For a System Administrator, It is a common task which is required on need to add together additional Network Interface. It may hold upwards required for dissimilar utilization i.e. Setup Bridge Interface, Setting upwards VLAN etc.

1 - Requirement :-In my scenario, I am using Centos release 6.4 (Final) Virtual Machine running on Hyper -V.

2 - Check Current Interfaces :-

We tin cheque electrical current available Network interfaces using below method.

A- Using dominance ifconfig -a

[root@testsvn  ]# ifconfig -a eth0      Link encap:Ethernet  HWaddr 00:15:5D:01:6B:00           inet addr:10.0.0.88  Bcast:10.0.1.255  Mask:255.255.254.0           inet6 addr: fe80::215:5dff:fe01:6b00/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:8710 errors:0 dropped:0 overruns:0 frame:0           TX packets:345 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:1049224 (1.0 MiB)  TX bytes:53714 (52.4 KiB)  lo        Link encap:Local Loopback           inet addr:127.0.0.1  Mask:255.0.0.0           inet6 addr: ::1/128 Scope:Host           UP LOOPBACK RUNNING  MTU:16436  Metric:1           RX packets:16 errors:0 dropped:0 overruns:0 frame:0           TX packets:16 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0           RX bytes:800 (800.0 b)  TX bytes:800 (800.0 b) 

B- Using dominance ip link

[root@testsvn  ]# ip link 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue dry soil UNKNOWN     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast dry soil UP qlen K     link/ether 00:15:5d:01:6b:00 brd ff:ff:ff:ff:ff:ff  [root@testsvn  ]#  

3- Now Add novel network interface from Hyper - V Console VM Setting.

- Shutdown your VM first

Right Click on (1) VM Go to VM (2) setting  

- Select (1) Add Hardware from left Action Menu, Choose (2) Network Adapter inwards the Hardware bill of fare list, Click on (3) Add button

Now (1) New network adapter will hold upwards displayed inwards left side menu, Select (2) required Virtual Switch, (3) Apply too (4) OK.

Start Virtual Machine afterwards applied higher upwards setting.

 

4- Check newly added interface :- 

[root@testsvn  ]# ifconfig -a eth0      Link encap:Ethernet  HWaddr 00:15:5D:01:6B:00           inet addr:10.0.0.88  Bcast:10.0.1.255  Mask:255.255.254.0           inet6 addr: fe80::215:5dff:fe01:6b00/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:4330 errors:0 dropped:0 overruns:0 frame:0           TX packets:269 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:489297 (477.8 KiB)  TX bytes:43043 (42.0 KiB)  eth1      Link encap:Ethernet  HWaddr 00:15:5D:01:6B:04           BROADCAST MULTICAST  MTU:1500  Metric:1           RX packets:3672 errors:0 dropped:0 overruns:0 frame:0           TX packets:19 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:406333 (396.8 KiB)  TX bytes:1898 (1.8 KiB)  lo        Link encap:Local Loopback           inet addr:127.0.0.1  Mask:255.0.0.0           inet6 addr: ::1/128 Scope:Host           UP LOOPBACK RUNNING  MTU:16436  Metric:1           RX packets:6 errors:0 dropped:0 overruns:0 frame:0           TX packets:6 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0           RX bytes:300 (300.0 b)  TX bytes:300 (300.0 b) 

Newly available interface is eth1

5- Let's configure eth1 interface too activate this adapter:-

please brand a complaint eth1 interface MAC address, inwards higher upwards event y'all tin run across MAC ID 00:15:5D:01:6B:04

Now practise a file ifcfg-eth1 nether this path :/etc/sysconfig/network-scripts/ifcfg-eth1

and append below line

[root@testsvn  ]# vi /etc/sysconfig/network-scripts/ifcfg-eth1 

DEVICE=eth1 HWADDR=00:15:5D:01:6B:04 TYPE=Ethernet UUID=d506b5c8-bc15-477e-9575-d6190f8304c7 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp  

Save and Exit from File.

6- Restart Networking service to utilize changes :

[root@testsvn  ]# service network restart

7- Let's cheque for IP address :-

Use dominance ifconfig or ip addr to cheque assigned IP address.

[root@testsvn  ]# ifconfig eth0      Link encap:Ethernet  HWaddr 00:15:5D:01:6B:00           inet addr:10.0.0.88  Bcast:10.0.1.255  Mask:255.255.254.0           inet6 addr: fe80::215:5dff:fe01:6b00/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:37772 errors:0 dropped:0 overruns:0 frame:0           TX packets:435 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:4249694 (4.0 MiB)  TX bytes:80131 (78.2 KiB)  eth1      Link encap:Ethernet  HWaddr 00:15:5D:01:6B:04           inet addr:10.0.0.127  Bcast:10.0.1.255  Mask:255.255.254.0           inet6 addr: fe80::215:5dff:fe01:6b04/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:5225 errors:0 dropped:0 overruns:0 frame:0           TX packets:28 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:580183 (566.5 KiB)  TX bytes:2792 (2.7 KiB)  lo        Link encap:Local Loopback           inet addr:127.0.0.1  Mask:255.0.0.0           inet6 addr: ::1/128 Scope:Host           UP LOOPBACK RUNNING  MTU:16436  Metric:1           RX packets:38 errors:0 dropped:0 overruns:0 frame:0           TX packets:38 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0           RX bytes:1900 (1.8 KiB)  TX bytes:1900 (1.8 KiB)  

We accept successfully added newly Interface too getting IP address from DHCP Server.

That's All

!!!Cheers!!!
