importance of having dedicated vCPU for BIG-IP VE installation ?

Can you help me check the importance of having dedicated vCPU for BIG-IP VE installation ?

 

For OVA installation, we have gone with VPC standard; (ie. no CPU reservation; no Thick provision)

 

Can you advise if we have concerns on: a.No CPU reservation b.No Thick provisioning

 

** Note: The VPC team monitors the whole Hypervisor Frame and ensure util of CPU never exceed 40%; and guarantee disk space availability even VM is provision is Thin.
