Hi
This is my first posting so bear with me.
I am trying to get qemu-kvm to work inside Virtualbox, but when I try to #modprobe the kvm-intel or kvm_intel module, it errors stating that operation is not permitted.
Is qemu known to run inside virtualbox? The host hardware is an i7 that supports hardware virtualization fine.
I have qemu running natively on the same box so it is confusing, but want to use VB also.
Thanks in advance.
That can't work, because you don't have access to the HW virtualization from the guest.
That's because CPU virtualization is basically nothing more than an additional CPU ring (ring-1) where the guest runs. To allow guests in guests in guests... there would have to be recursion in the HW itself (which I dare to say is impossible, there will always be a limit).

It can work. KVM supports nested support for their virtual machines which make it possible to run VirtualBox inside a KVM Guest. You will need VMX for it to work ( or the AMD counterpart ) and i don't think virtualbox supports this feature. http://networkstatic.net/nested-kvm-hypervisor-support/
