OpenStack Hypervisor

Learn about configurations >

• debug | boolean

• dns-servers | string

  Default: 8.8.8.8

• dpdk-control-plane-cores | int

  The number of cores allocated to OVS control plane processing. A dedicated list of cores will be obtained from the EPA service and passed to OVS through "other_config:dpdk-lcore-mask.

• dpdk-datapath-cores | int

  The number of cores allocated to OVS datapath processing. A dedicated list of cores will be obtained from the EPA service and passed to OVS through "other_config:pmd-cpu-mask".

• dpdk-driver | string

  Default: vfio-pci

  The driver used for DPDK physical ports.

• dpdk-enabled | boolean

  Enable OVS DPDK data path, handling packets in userspace. This provides improved performance compared to the standard OVS kernel data path. DPDK capable network interfaces are required.

• dpdk-memory | int

  The total amount of memory in MB to allocate from hugepages for OVS DPDK. The charm will distribute this memory across NUMA nodes based on the bridged network interfaces and then pass it to OVS using "other_config:dpdk-socket-mem".

• experimental-devmode | boolean

  Temporary flag to enable devmode snap install. This is needed until openstack-hypervisor interfaces are all stable.

• external-bridge | string

  Default: br-ex

• external-bridge-address | string

  Default: 10.20.20.1/24

• pci-device-specs | string

  A list of device specs used to set the pci.device_spec option in nova.conf, which allows PCI passthrough of specific devices to VMs.

  Example applications: GPU processing, SR-IOV networking, etc.

  NOTE: For PCI passthrough to work IOMMU must be enabled on the machine deployed to. This can be accomplished by setting kernel parameters on capable machines in MAAS, tagging them and using these tags as constraints in the model.

  Examples:

  • specify the PF address, exposing all the corresponding VFs: [{"physical_network": "physnet1", "address": "0000:1b:00.0"}]
  • pick VFs individually: [{"physical_network": "physnet2", "address": "0000:1b:10.0"}, {"physical_network": "physnet2", "address": "0000:1b:10.2}]
  • address wildcards: [{"physical_network": "physnet1", "address": ":1b:10."}, {"physical_network": "physnet1", "address": ":1b:}]
  • address regex patterns: [{"physical_network": "physnet1", "address": {"domain": ".*", "bus": "1b", "slot": "10", "function": "[0-4]"}}]
  • vendor and product id: [{"physical_network": "physnet1", "vendor_id": "8086", "product_id": "1563"}]

• physnet-name | string

  Default: physnet1

• reserved-host-memory-mb-for-sev | string

  Memory to be reserved for host for SEV enabled compute hosts. This memory will be used for instances. The compute usage report deducts this memory from the available memory sent to the placement service.

• resume-on-boot | boolean

  Default: True

  Whether to resume the guest VMs when the host boots.

• snap-channel | string

  Default: 2024.1/edge

• use-data-binding | boolean

• use-migration-binding | boolean
