https://support.citrix.com/article/CTX236977/overcommitting-pcpus-on-individual-xenserver-vms
 this document says "Citrix recommends that you do not run a VM with more 
virtual CPUs (vCPUs) than the number physical CPUs (pCPUs) available on the 
XenServer host"
   I think this is the reason we are setting based on host details.
   
   understood, thanks @harikrishna-patnala for the information.
   
   The following check applies on all hypervisor types, which might be good 
enough.
   ```
   boolean isCpuNumGood = host.getCpus().intValue() >= cpuNum;
   ```
