Hi Chintan,
This is more of Oracle VirtualBox virtualization issue than Spark issue. VT-x is hardware assisted virtualization and it is required by Oracle VirtualBox for all (64 bits) guests. The error message indicates that either your processor does not support VT-x (but your VM is configured to use this feature), or VT-x is (available but) disabled in your BIOS. To solve this problem, you have two options: a) enable VT-x in your machine BIOS (so that VT-x is enabled for all the VMs on your machine), or b) disable VT-x for the VMs, (in your case, Hortonworks VM) Hope this helps.
