Hello David, or anyone else affected,

Accepted landscape-client into trusty-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/landscape-
client/14.12-0ubuntu6.14.04.2 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-trusty to verification-done-trusty. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-trusty. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  [Impact]

  The new Amazon AWS C5 instance type is not a recognised VM type in
  Landscape and thus won't allow use of a Virtual Guest asset to
  register with.

  The C5 instance type is a new type that uses a KVM-family hypervisor
  instead of Xen (displaying "Amazon EC2" in sys_vendor which landscape-
  client doesn't recognise, thus cannot associate/map to kvm)

  "AWS has revealed it has created a new hypervisor based on KVM, not
  the Xen hypervisor on which it has relied for years."

  From
  https://www.theregister.co.uk/2017/11/07/aws_writes_new_kvm_based_hypervisor_to_make_its_cloud_go_faster

  [Test Case]

   * Deploy an AWS C5 instance
   * Look sys_vendor
     $ cat /sys/class/dmi/id/sys_vendor
     Amazon EC2

   * Install landscape-client
   * Register the client to the desired landscape-server
   * Verify "VM Type" to be "kvm" under the computer info (in landscape-server)

  [Regression Potential]

   * No regression anticipated, the fix is only adding a new entry
  mapping to recognize C5 instance (Amazon EC2)

  [Other Info]

   * Upstream commit:
     https://github.com/CanonicalLtd/landscape-client/pull/22/files
