Using SGX in Virtual Machines

clinton_b_ — Mon, 17 Oct 2016 23:40:57 GMT

In the following article ( http://wccftech.com/amd-zen-encryption-sme-sev-hw-based-sha/ ), it claims that SGX "cannot be virtualized".

Can SGX-based software run in a virtual machine?
If so, can I run SGX-based software(s) in different virtual machines on the same host concurrently?
Furthermore, If SGX-based software can run in a virtual machine, which virtual machines can it run in? VirtualBox? VMWare Workstation? Xen?

Thanks,

Clinton

I'm pretty sure SGX cannot

I'm pretty sure SGX cannot currently be run from within a VM.

What do you mean by currently?

Is it that VM's do not support SGX today? or SGX cannot run in a VM at all?

Virtualization software must

Virtualization software must be able to support, i.e., virtualize the SGX hardware features (extensions to the IA-32 instruction set). As far as I know, no virtualization software (VMware, VirtualBox, Xen, etc) has virtualized SGX..... yet. Until that happens, you won't be able to run SGX in a VM.

Don B. is correct.

Don B. is correct.

If you go to https://01.org/intel-softwareguard-extensions , you will see a link to https://01.org/intel-software-guard-extensions/sgx-virtualization. You should be able to find more details there.

Thank you everyone for the

Thank you everyone for the information!

As of right now, there is SGX

As of right now, there is SGX virtualization is available for KVM and Xen.
