  1. Hi Rick,

    I was running into a similar issue with the load average staying high in a Ubuntu 15.04 VM on Hyper-V under Windows 10. I had configured the Gen 2 VM with 2048 MB RAM and the ‘Enable Dynamic Memory’ box checked. In the course of trouble-shooting some other issues related to the VM not shutting down, I ran across a post pointing the finger at dynamic memory being the culprit. Unchecking the box resolved both the shutdown issue and the persistent high load issue. Let me know if you want any additional info or screenshots.

  2. Wow, this is soooo disappointing.
    I was so eager to give Hyper-V a try after I switched from Windows 7 to Windows 10 but the fact that there are such issues at the very beginning is making me ditch Hyper-V and use something else.
    I experienced not only that, but I was unable to create a virtual switch with external networking (got some “catastrophic error” <- that's what is said, really!) plus it screwed my ICS (Internet Connection Sharing).
    Oh and of course it makes VirtualBox not work at all (known issue though).
    The end result is that I'll be looking for a better alternative to Hyper-V.

  3. Hyper-V is fast and stable. A great hypervisor for Windows 10 users. However, it’s missing a bunch of features that puts it way behind VMWare Workstation, unfortunately.

    With the slow demise of Workstation there is a great opportunity for Hyper-V to become the preferred hypervisor for running both non-Windows server and desktop OSes. I really wish Microsoft upped their offering and became every bit as feature rich as Workstation:
    1. VMWare Unity, to hook apps running in a VM into Windows so that they launch from icons on the taskbar and run inside their own windows;
    2. True 3D acceleration for non-Windows apps. RemoteFX 3D Accelerator is only good for Windows 10 guests;
    3. Full support for non-Windows desktop OS display resolutions. Present the GPU directly to the guest and let them install a native driver;
    4. Full support for non-Windows type1 hypervisors (like KVM-QEMU), so that you can nest Virtual Machines inside a Hyper-V guest OS;
    5. An elegant GUI for the Hyper-V Manager that isn’t still harking back to Server 2008 days. Come on Microsoft, get with the times and build a frontend worthy of the desktop.

    With DevOps on the rise, Microsoft should benefit from stepping up and making Hyper-V on Windows 10 the best hypervisor option available for everyone wanting to run non-Windows guest OSes. Maybe they could hire the team that VMWare fired?

  4. I tried the above steps but in Win 10 the secure boot option is enabled and uneditable. Is there an easy way to disable secure boot?

  5. Thanks Rick, this pointed me in the right direction. The HyperV I have has a different option that worked for me and allowed me to choose a different Secure Boot template. I mention this as you’re the top Google hit, and folks who come here may find that useful to know!
