How to auto assign IP to Guest VM [KVM]?

Hi all,

Currently when I create a new VM, it obtains a private LAN IP and not able to connect to Internet unless I have to manually add my static IP then it's working fine.

Let's say I have 13 usable IPs, and I want one of them is auto assigned when I create new Windows 7 or Win Server 2008 VM on my dedicated server, how can I configure my network bridge to do so?

I'm running CentOS 6 64bit.

Thanks all

  • DHCP?

    Yes, I think this only can be done with DHCP, but I cannot configure my own IP range and seems VM's obtain IP from default libvirt's DHCP server, can you suggest?

  • I've found a way to do this is creates a virtual network with my own IP range, and routed to eth0 network-interface, then I create a new VM and it was auto assigned IP from my range, but no Internet connection, can't ping host IP, too :-(

    Can anyone help me figure it out?

  • Problem solved, mod please close this topic.

    Sorry, just thought no one cares about this.

    Btw, my solution was to install a new DHCP server, then I don't need to create a virtual network anymore, just choose bridge network interface when create new VM's.

    I used DHCP-4.1.1 for my CentOS 6, here some commands that may helps:

    $ yum install dhcp
    

    -Configure DHCP

    $ cat /etc/dhcp/dhcpd.conf
    

    -Configure listening Interface to DHCP

    $ cat /etc/sysconfig/dhcpd
    
    $ chkconfig dhcpd on
    $ service dhcpd start
