Package: virtinst
Version: 1:1.4.3-1

patrick at lab:~$ sudo apt-cache policy virtinst
virtinst:
  Installed: 1:1.4.3-1

I am unable to install an ubuntu virtual machine with the command
virt-install. Using this same command to create a Debian VM gives no errors
and is successful.

I have also tried using the 16.04 LTS version but that resulted in the same
error
Couldn't find hvm kernel for Ubuntu tree
