Hi,
I am running a duo core on Centos 5 on a server
I wish to install Virtualbox
- Is there a way to dedicate Virtualbox to ONE Core only ?
- If so, how can I do that ?
Thanks

This isn't really a VBox question, but more a straight Linux one. Google Linux processor affinity for relevant articles.

VB will only use one core per VM. There are some tools for Linux to set the affinity to a certain core, but it's best to leave it as is. The load will be divided over the two cores, switching from core to core or dividing the load evenly.

There are certain circumstances when use of processor affinity may be justified (for example, you have a mix of VMs which are running CPU bound applications but you want to ensure that they only take up a total of 100% of one CPU), but in general I agree with you. The average user would do well to leave this one tuning parameter alone.
