Hi I want to partition my OpenStack cloud so that:
- Project p1, p2, .., pn can use only compute nodes C1, C2, ... Cx - Projects pn+1.. pm can use only compute nodes Cx+1 ... Cy I read that CERN addressed this use case implementing the ProjectsToAggregateFilter but, as far as I understand, this in-house developments eventually wasn't pushed upstream. So I am trying to rely on the AggregateMultiTenancyIsolation filter to create 2 host aggregates: - the first one including C1, C2, ... Cx and with filter_tenant_id=p1, p2, .., pn - the second one including Cx+1 ... Cy and with filter_tenant_id=pn+1.. pm But if I try to specify the long list of projects, I get:a "Value ... is too long" error message [*]. I can see two workarounds for this problem: 1) Create an host aggregate per project: HA1 including CA1, C2, ... Cx and with filter_tenant_id=p1 HA2 including CA1, C2, ... Cx and with filter_tenant_id=p2 etc 2) Use the AggregateInstanceExtraSpecsFilter, creating two aggregates and having each flavor visible only by a set of projects, and tagged with a specific string that should match the value specified in the correspondent host aggregate Is this correct ? Can you see better options ? Thanks, Massimo [*] # nova aggregate-set-metadata 1 filter_tenant_id=ee1865a76440481cbcff08544c7d580a,1c63ef80901b46bebc9e1e8e10d85019,a22db12575694c9e9f8650dde73ef565,b4a1039f2f7c419596662950d8a1d397,d8ce7a449d8e4d68bbf2c40314da357e,e81df4c0b493439abb8b85bfd4cbe071,ee1865a76440481cbcff08544c7d580a,29d6233c0b2741e2a30324079f05aa9f,2b92483138dc4a61b1133c8c177ff298 ERROR (BadRequest): Invalid input for field/attribute filter_tenant_id.
