Ah... so there is 1 -2 ports in but the virtual space translates
multiples IPs on the network?
They just translate to virtual port. Even without virtualization,
you can put multiple IPs on the same network interface. For example,
the new server for wocommunity.org have two network interfaces
(ports) but the first port (eth0) also have 4 other IPs on virtual
interfaces (eth0:0, eth0:1, eth0:2, eth0:3)
As for VM, the virtual network interface in the VM will probably (at
least with VMWare and Xen) have 3 options: NAT, bridge, and private
network. For hosting stuff, you should use bridge.
Also, you should have a firewall + router in front of your
(hardware) server and that the server is using private IPs
(192.168.x.x) and the router is the one who should handle the public
IPs. So for example, if your ISP gave you 184.107.251.210 as a
public IP, that should go in the firewall + router and the router
will redirect traffic to your server and VMs. You have extra
security like this.
But anyway, if you have 8 servers (virtual or not), you still need 8
public IPs from your ISP.

I currently have a few WOInstances on different domains served

Virtualized...
If you have 8 instances of Linux with 8 different sites each
requiring an IP address then do you need a network card to the
server with 8 connection ports?
Each VM need at least one IP, and each VM will have a virtual
network card. You don't need a hardware card with 8 ports on it,
but I strongly suggest that either you get two network cards (if
the server have onboard ports, just add one card) so that you can
failover in case one of the ports blow up.

Hello Gino,
I'm actually setting up a Linux virtualized server for WO
(Debian).
I'm not done yet, but as far as your concerned, a virtualized
server is just a server, it can have one or multiple IP
addresses, but if you have 2 VM, you will have at least one IP
(different) for each.
So it's basically like having a "hardware" server.
At least that's what I think, I may change my mind when I'm done;)
Just re-reading your question, each instance must have its own
IP(s) like a "real" server.

Hi all
To those who have experience with virtualized Linux server...
If I set up a linux machine with virtualization and set up WO
Environments and Apache for each instance -
Does the individual instances of OS use the same IP address
shared across OSes?
So if one WOApp is on domain1.com and on OS Instance 1
And
WOApp2 is on domain2.com and on OS Instance 2
How do you deal with Virtual Server configuration?
