Question : Virtual Server on HYPER V assigning CPUs

I have 2 quad core xeon processors and I am putting 6 Virtual Servers on this machine. Each Server has enough memory however I wanted to assign more CPU power to each of the servers. What happens if I just set all the Virtual servers to 4 CPUs. Is there a problem doing this? Will the servers conflict fighting for CPU availability. We only have 10 employees connecting throughout the day using various applications. Or is it better to assign a static cpu number for each server? I want to know the goods and the bads.

I had 6 physical servers, each with it's own role. Now I want to keep one physical server as a domain controller and the other 6 will be as follows:

backup domain controller
sql 2005 server for production database (for all new records)
sql 2000 for older archived database (used to look at past records)
terminal server
webserver
exchange server

Answer : Virtual Server on HYPER V assigning CPUs

unless there is a desperate need to have more than one CPU, don't allocate the additional CPU as it will have a negative effect on performance.

my advise would be to monitor the performance of each server and then tweak CPU settings accordingly.
