learning KVM API
----------------
By default vCPU works under Real Mode which can we execute only 16-bit assembled code. We can not execute 32/64 x86 assembled codes. 

Basic operations:
1. Open kvm 
2. Create vm
3. Set memory for vm
4. Create vcpu
5. Set memory for vcpu
6. Create threads
7. Kvm_run
