A&AI Schema
ComputeNode, HPACapacity schema
Match Flavor Function (per vnfc)
For each flavor in cloud-region-flavor-list
For each hpaCapability in HPACapabilities requirement
Match hpaCapability in flavor
If matching hpaCapability found,
Check-Capacity(hpaCapacityKey, flavor, threshold).
Check-Capacity Function(input: hpaCapacityKey, flavor, threshold)
Get the compute Nodes associated with the input flavor.
getHPACapacityValue(hpaCapacityKey)
if( (free/total) < threshold): //Not enough capacity
return False and add to discard set
else:
return True and add to candidate list
getHPACapacityValue(hpaCapacityKey)
return from List of HPACapacity.get(hpaCapacityKey)

HPA PCIe Passthrough Policy Example | pciCount pciVendorId pciDeviceId | pciePassthrough | pci_passthrough:alias=ALIAS:COUNTOpenstack administrator is expected to create ALIAS as <name>-<PCIe vendor ID in Hex>-<PCIe device ID> QuickAssist example: "mycrypto-8086-0443" In case of SRIOV-NIC: aggregate_instance_extra_specs:sriov-device-<name>="<Vendor ID>-<Device ID>"It is expected that Openstack administrator creates host aggregate and metadata 'sriov-device-<name>' . Example: Assume that there are two SRIOV-NIC cards supported by a region, Intel and Mellanox.

HPA Huge Pages Policy Example | memoryPageSize | hugePages | hw:mem_page_size values can be ANY, 4KB, 2MB, 1GB How to handle large, small, any from openstack? if the hw:mem_page_size is an integer it is assumed the unit is in KB The deafult value for small page is 4k, for large page is 2M or 1G(recommended value 2M), for any page, libvirt will firstly to try to find large pages, if failed then will fall back to small pages. so it's suggest do not support any page in current release version | hpa-capability-id="e769fd3d-0b15-77b3-81b2-6210efc6dffa", hpa-feature=”hugePages”, architecture=”generic", version=”v1”,
