While installing RHEV Hypervisor 3.3 on Oracle VirtualBox I am getting following message:

Failed to open a session for the virtual machine RhevH1
VT-x is used by another hypervisor.
(VERR_VMX__IN_VMX_ROOT_MODE).
VirtualBox Can't operate in VMX root mode. Please disable the KVM
kernel extension, recompile your kernel and reboot
(VERR_VMX_IN_VMX_ROOT_MODE).

What are the possible solutions are there for this?

    This is basically the same question as . You can't run VMs on VMs. That's what the error about VT-x is telling you :) – mirimir Jun 09 '14 at 09:13
  • No both are different on is for Virtual Machine Manager and another is for Oracle VM Box. – user3134198 Jun 09 '14 at 09:18
  • OK, they're not identical. But I guarantee that you'll get more or less the same error trying to run RHEV on any sort of VM. – mirimir Jun 09 '14 at 09:22

VirtualBox does not support running any kind of native virtualization software inside it (VirtualBox itself, KVM/RHEV, Hyper-V, ESX, Xen in full virtualization mode, …).

Run RHEV directly on the hardware.

RHEV hypervisor can run nested under kvm or vmware, but vbox doesn't support nesting, and willnot expose virtual functions inside the VM. Nothing to do with RHEV, this is a vbox limitation.
