In 21.0.0 Ussuri we were completed the nova-cyborg interaction feature, but there are some issue when multiple create instances. Creating servers with accelerators provisioned with the Cyborg service, if a flavor asks for resources that are provided by nested Resource Provider inventories (eg. VGPU) and the user wants multi-create (ie. say --max 2) then the scheduler could be returning a NoValidHosts exception even if each nested Resource Provider can support at least one specific instance, if the total wanted capacity is not supported by only one nested RP. For example,creating servers with accelerators provisioned with the Cyborg service, if two children RP have 4 VGPU inventories each: - you can ask for a flavor with 2 VGPU with --max 2 - but you can't ask for a flavor with 4 VGPU and --max 2 Related-Bug: #1874664 Change-Id: I64647a6ba79c47c891134cedb49f03d3c61e8824

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
