Im planing to set up two virtual machines in a dell server with two ethernet ports. My question is.
what is better a virtual server for each port (100Mbps each port) or using just one server. Assuming that the two ports will contvine making the speed of one server 200Mbps?

I think you are right but im still researching the way the two ports will be bundle. Thank You

What you are talking about is link aggregation. This is where a group of physical NICs function in a team as one larger NIC. If you only have 10/100 ethernet ports, it's not even worth it. Get a cheap add-in gigabit NIC for your server and use that for bandwidth. If you're wanting to stream video, especially anything HD, you're going to need all the bandwidth you can get, and even a link aggregated 200 Mbps is not going to cut it.

Furthermore, to get link aggregation to work in Windows 2008 your NIC also has to have supported drivers with that feature, and your network switch also has to be configured with link aggregation on the two ports connected to the server.

The question you have is actually not related to virtual servers, but rather has to do with the idea of link aggregation. Link aggregation is the practice of combining multiple network connections such that they work in parallel. This serves two main purposes: the throughput of the connection can be higher than that of a single connection, and redundancy exists as the other connections will continue to function in the case one fails. Link aggregation has several major aspects that must be considered.
Firstly the operating system you are running on the server (which will be doing the OS-side aggregation must be compatible with your network interface cards for aggregation.
Secondly, the network infrastructure at your datacenter (or wherever your server is located) must be configured to aggregate traffic to the ports connected to your NICs.
Finally both of the aforementioned must be configured in tandem to ensure your setup is efficiently using hardware resources.That being said, for a video streaming site with anything more than a couple users, especially for high definition video, 200mbps will not be enough. You will need to look into a far higher throughput solution (i.e.-multi gigabit) to maintain multiple streams.
