Do you have any educated guess as to when you might switch to deploying new OpenStack version exclusively on RHEL 7 ? I understand such a switch is likely to take a while so you can test its performance and reliability and so on, but I'm assuming you'll eventually switch ? > However, since this modification would only take place when Mitaka gets > released, this would realistically give those sites a year to complete > migration to RHEL/CentOS 7 assuming they are running from one of the > community editions. > > What does the 1.1.1 version bring that is the motivation for raising the > limit ? If we require 1.1.1 we could have unconditional support for - Hot-unplug of PCI devices (needs 1.1.1) - Live snapshots (needs 1.0.0) - Live volume snapshotting (needs 1.1.1) - Disk sector discard support (needs 1.0.6) - Hyper-V clock tunables (needs 1.0.0 & 1.1.0) If you lack those versions, in case of hotunplug, and live volume snapshots we just refuse the corresponding API call. With live snapshots we fallback to non-live snapshots. For disk discard and hyperv clock we just run with degraded functionality. The lack of hyperv clock tunables means Windows guests will have unreliable time keeping and are likely to suffer random BSOD, which I think is a particularly important issue. And of course we remove a bunch of conditional logic from Nova which simplifies the code paths and removes code paths which rarely get testing coverage.
