So in the end I don't think this is a Nova bug. The first line of the request to the Nova API server looks like this:
DELETE /v2/f9cea8784d7245e5a8022a259bb92d90/os-server- groups/{u'policies': [u'affinity'], u'name': u'server-group-1646113520', u'id': u'b5316a4a-f6eb-4a7f-8b24-028b799bf6a9', u'members': [], u'metadata': {}} HTTP/1.1 Which is not a valid header. It is so badly formatted that I believe a reasonable parser implementation could not necessarily know that the client is requesting a response in HTTP/1.1 format as the uri is so corrupt. Looking from the end it can be clearly seen, but the request is definitely corrupt. BaseHTTPServer by default responds in HTTP/0.9 protocol if its not sure. So it does return a 400, but in HTTP/0.9 protocol: <title>Error response</title> </head> <body> <h1>Error response</h1> <p>Error code 400. <p>Message: Bad request syntax ("DELETE /v2/f9cea8784d7245e5a8022a259bb92d90/os-server-groups/{u'policies': [u'affinity'], u'name': u'server-group-1646113520', u'id': u'b5316a4a-f6eb-4a7f-8b24-028b799bf6a9', u'members': [], u'metadata': {}} HTTP/1.1"). <p>Error code explanation: 400 = Bad request syntax or unsupported method. </body> httplib2 on the tempest side made the request in HTTP/1.1 protocol, but does not appear to try to parse it in HTTP/0.9 format if it doesn't get an HTTP/1.1 header. According to RFC 1945 it should be able to do so. So technically its a tempest bug. Not sure if its worth fixing though.... ** Also affects: tempest Importance: Undecided Status: New ** Changed in: tempest Importance: Undecided => Low ** Changed in: nova Status: Confirmed => Invalid -- You received this bug notification because you are a member of Yahoo!

But the call returns 200.
