Hi Everybody;
Thank you in advance for any help you can give. I have searched and searched and have not found an answer to my issue. I'm not sure if this should be in virtualisation or networking - since it's mostly a networking question, I'll ask here.
I have a rent-a-server with one NIC and two real-world IP addresses. The first IP, 69.xxx.xxx.xxx, is the actual IP address of the server. The second IP, 209.xxx.xxx.xxx, is an IP alias. The interface is defined as follows:
# loopback interface
auto lo
iface lo inet loopback
# ethernet interface
auto eth0
iface eth0 inet static
address 69.xxx.xxx.xxx
network 69.xxx.xxx.0
netmask 255.255.255.0
broadcast 69.xxx.xxx.255
gateway 69.xxx.xxx.1
# virtual interfaces
auto eth0:0
iface eth0:0 inet static
name Ethernet alias LAN card
address 209.xxx.xxx.xxx
netmask 255.255.255.255
The 69.xxx.xxx.xxx address has a web server and a number of functioning services on it. The 209.xxx.xxx.xxx address is a recently purchased address. It "pings" as defined above. I've no previous experience with IP aliases, but as I understand it, the address is NOT associated with a network at all. There is no broadcast or gateway associated with the address.
I am attempting to install a product that functions within a virtual machine hosted on the same server. I want the virtual machine to be addressed by the 209.xxx.xxx.xxx address. The pre-built VMWare based virtual machine obtains its IP through DHCP. Both the host and virtual machine are Ubuntu 10.04 server. I would prefer to change the VM to use the 209.xxx.xxx.xxx static IP, but have no idea how to set that up since there is no actual network/broadcast/gateway. When I attempt to set up the dhcp3-server on the host, it fails to start, issuing the error message: "No subnet declaration for eth0:0 (0.0.0.0). ** Ignoring requests on eth0:0." as if the eth0:0 interface is not up. The eth0:0 is, however, up.
Anyone know how to set the above scenerio up? Is it even possible with an IP alias?
Thanks,
