Obviously a bit late, but just for clarity, no topics from our side this month. Not clear yet what will be ready for discussion next month, but lets put the date in the diary and discuss an agenda nearer the time.
As promised, the Code-first ECR to enable virtual CPU hotplug was published:
I believe we should coordinate effort around bits and pieces that we need to upstream to enable it.
Thanks for the link. A few questions from a quick read. It's been a while so I may well have forgotten how the flows work...
The online capable bit is documented as being reserved and zero if Enabled is set. This seems to rule out using it for information on CPUs that are initially enabled but which we may want to later remove from a given VM? We could just enable a flow where such CPUs have to be enabled after boot, but that seems unnecessarily limiting.
What is the point in a non present bit that must always be zero? I assume this is about leaving space for a future physical hotplug but even so it seems unwise to drop in a field that must be zero. My inclination is don't define this bit until you need it - will be reserved 0 anyway so I'm not sure I see why it needs reserving.
Agreed that we need to coordinate efforts to get this enabled upstream.
