Hi Folks, I'm looking for a capability to limit some flavours to some hosts. I want the mapping to be as flexible as possible, and work within a zone/cell (I don't want to add zones just to get this mapping). For example I want to express something like:
Host_1 supports flavours A, C Host_2 supports flavours A, B Host_3 supports flavours A, B, C Host_4 supports flavours D Ideally there would be some form of grouping to sets of flavours: Flavour_A is part of Flavour_Sets 1, 2, 3 Flavour_B is part of Flavour_Sets 2, 3 Flavour_C is part of Flavour_Sets 1, 3, 4 Host_1 supports flavour Set 1 Host_2 supports flavour Set 2 Host_3 supports flavour Set 3 Host_4 supports flavour Set 4 >From the Essex design summit I thought that host aggregates was going to give >this sort of capability, but having looked through the code that seems to be >quite tightly coupled with specific hypervisor functionality, whereas this is >purely a scheduler feature. I can see that I could define flavour group membership through the instanace_type_extra_specs, but not how to then associate these with specific hosts. I know I'm a tad behind some of the recent changes - so before suggesting a design summit session on this I thought I'd ask - is there something that already does this type of mapping ? Cheers, Phil
