  [Impact]

   * Users are unable to virt-install using xenial and newer isos.

  [Test Case]

  Domain installation does not appear to have been successful.
  If it was, you can restart your domain by running:

  otherwise, please restart your installation.

  [Regression Potential]

   * Patch is accepted into upstream virt-install

   * I have run virt-install against both iso's and netinstall trees
  *(which previously worked and now continue to work).

  [Other Info]

  
  +++++++++++++++++++++++++ Original Description ++++++++++++++++++++++++
  I am trying to create a new virtual machine with Virtual Machine Manager but keep receiving this error "Unable to complete install: 'Couldn't find hvm kernel for Ubuntu tree". The OS guest I am trying to install on the VM is Ubuntu server 14.04.4, 64 bit. The host OS (where the virtual manager is installed) is KUbuntu 16.04 .

  Below is the full message that appears after completing the 5-steps VM
  creation process and clicking on finish on virt-manager:

  Unable to complete install: 'Couldn't find hvm kernel for Ubuntu
  tree.'

  Traceback (most recent call last):

  Description: desktop application for managing virtual machines
   It presents a summary view of running domains and their live performance &
   resource utilization statistics. A detailed view presents graphs showing
   performance & utilization over time. Ultimately it will allow creation of new
   domains, and configuration & adjustment of a domain's resource allocation &
   virtual hardware.  Finally an embedded VNC client viewer presents a full
   graphical console to the guest domain.
   .
   NOTE: the GUI is still considered experimental.

  According to this discussion http://askubuntu.com/a/815056 on
  Askubuntu.com, it is matter of an issue with the installer (virt-
  install looking for i386 installer but should be looking for amd64
  installer). The bug is reportedly fixed on upstream, but not available
  yet for the packages.
