Re: [openstack-dev] [hyper-v] Hyper-V Support Will be Removed Forever ?

2017-11-24 Thread Alessandro Pilotti 
Adam,

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.

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.

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 ;)

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.

According to my past experiences with Hyper-v Microsoft's hypervisor heavily 
uses block layer caching also for guest read/write operations.
AFAIK this is very different to Linux+KVM or VMware where there is no caching 
for vm guests.

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.

Hello,

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.

I know cloudbase.it working hard for port too much thing 
but ı would like to learn really Hyper-V hypervisor support will be removed 
from Openstack forever ?

Hyper-V support in OpenStack is alive and well, see for example this blog 
series comparing KVM and Hyper-V: [1].

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
