I can reliably reproduce this issue via the following steps:
1) Create blah.py under nova/api/metadata/ with these contents:
from nova.api.metadata import base
class CustomVendordata(base.VendorDataDriver):
def __init__(self, *args, **kwargs):
super(BcpcMetadata, self).__init__(*args, **kwargs)
def get(self):
return {"msg": "", "uuid": "4996e2b67d2941818646481453de1efe", "users":
[{"username": "erhudy", "sshPublicKeys": [], "uuid": "erhudy"}], "name":
"TestTenant"}
2) Configure Nova to use that class as the vendordata_driver in
nova.conf:
[DEFAULT]
vendordata_driver = nova.api.metadata.blah.CustomVendordata
3) Restart nova-api.
4) Launch an Ubuntu cloud instance on that hypervisor.
5) Experience cloud-init fury:
