We had a dedicated server running with XEN which host 7 cPanel VPS. Later we configure KVM and SolusVM. After installing KVM, performance of the VPS and dedicated node itself really slow. Already talk to SolusVM regrading this and they are not able to provide solution for that. Do you have same problem with the KVM or am I missing any configuration ? Dedicated Server has Intel i7 920 CPU with 12 GB DDR 3 memory.

Can you give the output of free command? This will tell you how much RAM you have free. Your machine might be swapping, and causing it to run slower.
