Hello Alex, or anyone else affected,
Accepted landscape-client into artful-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/landscape-
client/16.03-0ubuntu3.17.10.3 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-artful to verification-done-artful. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-artful. 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!

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
Status in landscape-client source package in Artful:
Fix Committed
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.
