I know there are programming guides in enabling sgx with VM in the "Intel® Software Guard Extensions Programming
Reference", but I haven't found any existing VMM products supporting that. There is an SGX_ERROR_HYPERV_ENABLED in "Intel® Software Guard Extensions User's Guide for Windows* OS", but I havn't found any hyper-v release note regarding with SGX.

Intel SGX technology is available in all VMs.You have to check with ISV's release note for Microsft hyper-v

So do you mean SGX feature is default to open and available to VMs as soon as the host bios enabled the SGX feature? Currently no configuration option with SGX is available to all the mainline hypervisors, including VMware Workstation, Virtualbox, Xen, Kvm. I havn't tried the latest hyper-v, but that on windows server 2008 r2 has no configuration option for SGX too.
