Can we make virtual machines in RHEL6 with each having static ip's and have individual connection from other network and without using a bridge.

What is the output of 'ip addr show' and 'brctl show'? – sciurus Mar 18 '11 at 14:12

Either you need a seperate hardware NIC assigned to each virtual machine using pci passthrough, or you need to use bridged networking.

there are two ways to go about networking - use a bridge or use NAT. The preferred way is to use a bridge, since this places the VM in the same network with the rest of the involved machines, the bridge acting like a virtual hub for the VMs. What exactly are you trying to achieve?

Hi dyasny, i configured the host with ip and the virtual machines with static ip's The issues came when we moved the server to hosting center and there was lot of connection problems to the VM's. – nicepuli Mar 17 '11 at 15:54
Here is the ifconfig of Host: bridge0 Link encap:Ethernet HWaddr E4:1F:13:63:37:2C inet addr: Bcast: Mask: eth0 Link encap:Ethernet HWaddr E4:1F:13:63:37:2C lo Link encap:Local Loopback inet addr: Mask: vnet0 Link encap:Ethernet HWaddr FE:54:00:E6:D4:FB inet6 addr: fe80::fc54:ff:fee6:d4fb/64 Scope:Link – nicepuli Mar 17 '11 at 15:55
Is the issue of network because i assigned the same network range to the VM's as well as the Host. Which is the best solution, change host ip or change VM ip's?How can i map the Changed IP to the Users Assigned IP. – nicepuli Mar 17 '11 at 16:01
