<div>Adam,</div>
<div><br>
</div>
<div>If you used an old version of Hyper-V and especially old versions of LIS, there’s a night and day difference compared to recent versions. Don’t forget that Hyper-V technology is used in Azure, so MSFT has all the reason to invest on optimizations.</div>
<div><br>
</div>
<div>Getting to the benchmarks, all Rally tests scenarios that we used are open source, especially because we wanted people to run the same tests on their environment and validate them, instead of blindly believe our results.</div>
<div><br>
</div>
<div>If this isn’t objective enough for you, feel free to propose any change or come up with other scenarios, but please respond with data instead of FUD ;)</div>
<div><br>
</div>
<div>As for VMware, they have a clause in the EULA that forbids to publish benchmarks unless they approve them (!!), so I can’t comment on that unfortunately.</div>
<div><br>

<div dir="ltr">In regards to these benchmarks honestly I don't think that the measurement results are objective enough.
<div>According to my past experiences with Hyper-v Microsoft's hypervisor heavily uses block layer caching also for guest read/write operations.</div>
<div>AFAIK this is very different to Linux+KVM or VMware where there is no caching for vm guests.</div>

<div>Hyper-V support in OpenStack is alive and well, see for example this blog series comparing KVM and Hyper-V: [1].</div>
<div><br>
</div>
<div>The fact that SUSE / HPE might or might not support it, is just a matter of commercial choices unrelated to the upstream projects (which is what matters in this ML). Other vendors (e.g. Red Hat, Mirantis, Canonical) have partnership with us (Cloudbase)
for Hyper-V commercial support. </div>

<p class="MsoNormal"><span lang="TR" style="font-size:11.0pt">We are using HPE Helion Openstack . For a long time they are always removing hyper-v support from their distro. We started to discuss with SUSE and i believe everybody know HPE HOS and SUSE Openstack
are migratated and it will become single product and we learn from SUSE they are also stop supporting Hyper-V.
