Microsoft has not yet chimed in officially on the OpenStack newsgroup thread that popped up last week or following a ReadWriteWeb story about the issue that appeared Monday. So far Tim Bell, who works with CERN, is the only person who has indicated he'd like to continue support for Hyper-V. CERN does not appear to be using Hyper-V with OpenStack in a production environment, but an October presentation posted online indicates it hoped to at least try using Hyper-V in its OpenStack environment once the support was available.
"Are there other sites who are affected by this proposal who would be willing to invest effort to maintain the Hyper-V support?" Bell wrote on the newsgroup thread.
Based on the rest of his post, the issue for Bell and potentially others is getting support from Microsoft if they are running Windows 7 and Windows Server as guests in OpenStack using a hypervisor other than Hyper-V. Microsoft will in fact offer support in that scenario if the hypervisor being used is part of its Server Virtualization Validation Program.
Without an outcry against dropping support for Hyper-V for now, the code could be dropped soon. A member of the community could decide to do the work to remove the code this Thursday during a scheduled bug squashing day at OpenStack, McKenty said. That action would be reviewed by the 45-member core team at OpenStack, which he's a member of.
Barring an outcry, the only reason he can see for deciding to keep the code in place would be if the core team determines that it's too big of a change to make since there is a freeze on feature changes at this stage in the development of the new version of OpenStack Compute, McKenty said.
Meanwhile, based on its statement, Microsoft could be looking for another partner to help with the development of Hyper-V support in future versions of OpenStack. The company must be careful with how it works with open source communities due to its historical run in with antitrust authorities, Staten said. That means Microsoft is likely to partner with a contractor again, rather than do the work itself.
Regardless, even if Hyper-V support is removed from the next version of OpenStack, it doesn't necessarily mean it won't be back, he said. "It's less of a dropping and more of a deprioritization," Staten said. Without a significant number of cloud vendors committed to building OpenStack on Hyper-V, "there's no point doing the engineering work at this time."
