Solved: Ubuntu install hangs on Hyper-V

Published November 29, 2015 by FoxDeploy

Recently, I’ve been getting more and more interested in Chef, and decided it was time to build out a testlab in my Hyper-V.

I started imaging a new VM using the 14.10 LTS release of Ubuntu, one of the supported environments for Chef Server.

However, during install, my VM would freeze here:



At the same time, I noticed a critical level event from Hyper-V.

‘VMName’ was faulted because the guest executed an intercepting instruction not supported by Hyper-V instruction emulation. If the problem persists, contact Product Support. (Virtual machine ID 8895146E-C175-4CA5-B7A6-57E1D6E48290)


I did a bunch of googling and found…almost no one with this same issue, and I thought it was related to Hyper-V on Windows 10 Tech Preview.  As it turns out, this is caused by some generation 2 Virtual Machine features, namely Dynamic Memory.


Install of Ubuntu or other *Nix distro freezes during install on Hyper-V, as a Gen 2 VM


Dynamic Memory does not appear to be supported during install of Ubuntu, and will manifest as errors during OS Install and Parititoning


Disable Dynamic Memory until install is completed.  After installing, run ‘sudo apt-get update’ to ensure drivers are up to date, for optimum VM sveltness.
