TRAITS = [
# The virt driver supports associating a tag with a device *at boot time*
'DEVICE_TAGGING',
# A provider with this trait is a compute *node*. (As distinct from
# "compute host" or "hypervisor". These may be synonymous in some cases,
# but the distinction matters e.g. when using the ironic virt driver.)
'NODE',
# The virt driver supports trusted image certificate validation
'TRUSTED_CERTS',
# The virt driver supports cold migrating to the same compute service host.
# This really only works for a cluster-type hypervisor driver like the
# vCenter driver which is a single compute service host managing a vCenter
# cluster of potentially hundreds of ESXi hosts. Note that this trait will
# not make sense to use in GET /allocation_candidates until/unless there is
# a way to tie it to the condition of SAME_HOST-ness.
'SAME_HOST_COLD_MIGRATE',
# The virt driver supports rescuing boot from volume instances.
'RESCUE_BFV',
# The compute manager supports handling accelerator requests.
'ACCELERATORS',
# The compute manager supports the `socket` value for the
# hw_pci_numa_affinity_policy image property/flavor extra spec.
'SOCKET_PCI_NUMA_AFFINITY',
# The compute manager supports handling remote_managed PCI devices
# associated with SmartNIC DPUs.
'REMOTE_MANAGED_PORTS',
# The compute manager is configured to support file-backed memory.
# https://docs.openstack.org/nova/latest/admin/file-backed-memory.html
'MEM_BACKING_FILE',
# Nova use this to indicate that an RP has inventories of PCI device(s)
# managed by the nova-compute service
'MANAGED_PCI_DEVICE',
# The virt driver supports pass-through or emulated modes for guest
# physical address bits.
'ADDRESS_SPACE_PASSTHROUGH',
'ADDRESS_SPACE_EMULATED',
# The compute manager supports share local fs (via virtiofs)
'SHARE_LOCAL_FS',
