How to enable Nested Virtualization for Android Emulator

Hi
Has anyone been able to enable Nested Virtualization for Android Emulator?

I’ve been reading about it but couldn’t figure out how to do it

No virtualization is available in a HVM qube

R: won't do

### Qubes OS version:  R4.0 ### Affected component(s): Depending on the outcome of a risk and threat assessment, it might be allowable to enable nested virtualization in HVM mode. E.g., I'd like to run GNS3 in a HVM based Linux distribution. Without proper support for nested virtualization, that won't work / perform. --- ### Steps to reproduce the behavior:  - Install your favorite Linux distribution in a HVM-based qube. - Install VirtualBox in that HVM. - VirtualBox will complain that VT-x/AMD-V hardware acceleration is missing. ### Expected behavior: Hardware acceleration should be availabe in HVM. ### Actual behavior: Currently I'm unable to run GNS3 in a Linux based HVM with acceptable performance. ### General notes: I will not participate in a flame war on nested virtualization. ;-) I'm aware of risks introduced by nested virtualization. In my situation, I've done the assessment and I accept these risks. --- ### Related issues: I'm more than happy to patch Qubes myself to make this possible. E.g., there is https://groups.google.com/forum/#!msg/qubes-devel/UzO0BsIfIow/wWjpd3IPAgAJ which already contains a patch. Is it really that simple to enable it? Or did things change massively between then and now. There is also https://wiki.xenproject.org/wiki/Nested_Virtualization_in_Xen#Current_status, which I don't understand, because it looks to me that newer versions of Xen won't work but older versions do? Maybe I greatly underestimate the complexity of this matter ...
