    Has anyone had any luck running Hyper-V 2012 r2 core as a nested hyper-v server? I have been trying for a day now and I can get it up and running for a few minutes at a time before it goes to a small blank window and stop responding. I've not even been able to get to the point of running a VM on Hyper-V yet.

    I'm running Parallels Desktop 11 for Mac Pro Edition build: 32408 on a Mac Mini (late 2014), Intel Core i5, 16Gb RAM 256Gb SSD. OS X El Capitan v 10.11.3

    Hi Bcampbell, please refer to this article to fix to enable "Enable Nested Virtualization checkbox" and let us know how it works.

    Hi Paul

    Been there already, its not that I'm afraid. Nested Virtualisation has always been enabled.

    Just enabled the Hyper V role on what was a working Windows 10 VM (Enabled nested Virtualisation checked). The VM no longer starts. I think nested virtualisation is broken in Parallels.

    as far as I know there are some issue with Hyper-V VMs memory paging right now. I'd suggest you trying the previous builds: http://download.parallels.com/desktop/v11/11.1.1-32312/ParallelsDesktop-11.1.1-32312.dmg

    - delete the current one from /Applications
    - Install the previous (do not agree to update during installations)
    - run VM and reinstall Parallels Tools
    - check the issue

    I'm running win 2012 r2 Hyper-V server with 3 nested Win8.1 VMs. it works fine. Keeping in mind that Server 2012 R2 and Win8.1 have the same kernel, I guess downgrading to previous build should work for you.

    btw, I'm running it on macmini late 2014 =)

    Just got a 2012 Hyper-V Core Host installed there. Everything was a breeze, it does seem to be an issue with the latest build. Will get some VM's running this afternoon. Thank you @Marat@Parallels for your help with this.
