Azure always uses little-endian for the first three fields in the uuid. This behavior was made strict in SMBIOS 2.6+, but Linux and dmidecode follow RFC 4122 and assume big-endian for earlier SMBIOS versions. Azure's gen1 VMs use SMBIOS 2.3 which requires byte swapping to match compute.vmId presented by IMDS. Azure's gen2 VMs use SMBIOS 3.1 which does not require byte swapping. :raises ValueError: if UUID is invalid. zFailed to parse system uuid: %r)Úbytes)ÚuuidÚUUIDÚ ValueErrorÚLOGÚerrorÚstrÚbytes_le)rÚ original_uuid©rúB/usr/lib/python3/dist-packages/cloudinit/sources/azure/identity.pyÚbyte_swap_system_uuids  þrcCstƒrt|ƒS|S)z!Determine VM ID from system uuid.)Ú is_vm_gen1r©rrrrÚconvert_system_uuid_to_vm_id'srcCs$tj d¡rdStj d¡rdSdS)zZDetermine if VM is gen1 or gen2.
