Sorry, for not mentioning this earlier. I am moving the 
kvm_arch_init_vm() call mainly to go after mutex_init(&kvm->slots_lock) 
since I am calling the x86_set_memory_region() (which uses slots_lock) 
in the vm_init() hooks (for AVIC initialization).

Lemme re-check if this would be safe for other code.

Thanks,
Suravee
