Title:
  Instances on Apache CloudStack using KVM hypervisor are not detected
  as virtual machines

Status in Landscape Client:
  Fix Committed
Status in landscape-client package in Ubuntu:
  Fix Released

Bug description:
  [Impact]

   * This issue affects users of Apache Cloudstack instances by failing to
     detect the hypervisor type and reporting the clients as running on
     a physical machine instead of on KVM.

   * This fix extends dmi vendor mapping, so that clouds customizing sys_vendor
     chassis_vendor or bios_vendor values (e.g. CloudStack, DigitalOcean)
     still get detected as KVM instances.

  [Test Case]

  The issue can be reproduced on libvirt/kvm.

  uvt-kvm create vm
  virsh edit vm

  <os>
  ...
  <smbios mode='sysinfo'/>
  </os>
  <sysinfo type="smbios">
    <system>
      <entry name='manufacturer'>Apache Software Foundation</entry>
      <entry name='product'>CloudStack KVM Hypervisor</entry>
    </system>
  </sysinfo>
  <cpu match='exact'> <!-- defaults to qemu, which would me detected correctly -->
    <model fallback='allow'>core2duo</model>
    <vendor>Intel</vendor>
  </cpu>

  virsh destroy vm && virsh start vm
  uvt-kvm ssh vm --insecure
  sudo landscape-config --log-level=debug -a devel --silent -t testclient
  # will fail registering, but that's not relevant to the vm-type detection
  grep vm-info /var/log/landscape/broker.log
  # expected output is "KVM", and will be empty because of this bug

  [Regression Potential]

   * Like the previous update, this change is local and only affects vm-type
     detection, which should be low-risk.

   * Since we extend the current detection to fields we were not previously
     looking at, one of the risks is to falsely detect clients as running
     on KVM. This is why we took care to verify opposite scenarios in
     addition to making sure the existing unit tests pass. Were such a
     regression to occur, it would have a low user impact, as being detected as
     VM you can use either physical or VM license, whereas the opposite
     (due to the bug fixed here) is not true.

  [Other Info]

   * AWS and DigitalOcean instances have been fixed slightly differently in
     the previous SRU, but we wanted to avoid repeating this for every other
     cloud, thus extending the DMI field lookup instead of adding yet another
     mapping value.

  [Original Description]

  Instances running on a Apache CloudStack that is using KVM as a
  hypervisor are not detected as virtual machines by the landscape-
  client. They are using a Full license to register instead of a Virtual
  one.
