Centos 7 VM Host Network Configuration For VM Guest FW Server

Post by singh_ravinder123 » 2017/10/06 06:13:31

Hi,
My query is related to CentOS Virtualization - Virtual Network configuration.
I have a HP Proliant Server machine with 4 ethernet cards. I Installed CentOS 7 with Virtualization support on it. I have created following :-

1. VM1 - VM guest which has to work as Firewall Server with 2 Network Cards (1 WAN, 1 Internet LAN).
2. VM2 - Another VM Guest which has to work as LAMP with 1 Network Card (1 Internet LAN).
3. VM3 - VM guest which has to work as NMS with 2 Network Cards (1 Interrnet LAN, 1 Management LAN)

Now I need this:-

1. 1st Ethernet Card should work for WAN Network only.
2. 2nd Ethernet Card should for work for Internet LAN and that has to shared with VM1 and VM2.
3. 3rd Ethernet Card should work for Management Network and also shared with VM2. I want to access my VM Host and VM3 on this port from my PC in this LAN.

Please guide. If any other better method to use these resources also welcomed.

Thanks for your valuable time.

regards,
Ravinder Singh.

Should I have to create a bridge interface for each physical ethernet card. And after that assign network interface to that bridge accordingly above requirement.

1. eth0 ---------- WAN ---------------vm1eth0 - VM1 *Firewall server WAN Interface
2. eth1 <- br1 -- Internet LAN -----vm1eth1 - VM1 *Firewall server LAN Interface
___eth1 <- br1 -- Internet LAN -----vm2eth0 - VM2
3. eth2 <- br2 -- Manag LAN -----vm2eth1 - VM2
___eth2 ---------- Manag LAN ----- eth2 - VM Host * to access VM Host from Management VLAN
4. eth3

Please Guide.
