Terminal Server 2008 r2 too slow on Virtualbox headless on CentOS 5.5


Hello,

I'm having performance problems with Virtualbox... I've been googling around and it seems like Virtualbox is not the fastest/best for the performance I need in CentOS, could anybody tell me which Virtualization software is the best in terms of performance for CentOS 5.5?

I have a:

Proliant Server,
Xeon 3.6
1 TB HDD
6GB RAM, I am using 4GB for the VM
Running CentOS 5.5 as host and Windows 2008 Server R2 SP1 as a Virtualbox guest


Thanks in advance.
Arthur Carrillo.

Centos 6.4 (if possible), KVM, load the paravirtualised drivers for Windows for the network and the scsi block devices. This will give you undiscernable bare metal performance.

kvm and libvirt are by default non-graphical, driven by CLI. You can use virt-manager, for a GUI, but it's an addition, not a must
