I believe this was an eventlet issue. Given age, I'm going to move this
to invalid. If it is observed again, please file detailed new bug, or
reopen this one.

Title:
  Long ironic timeouts because of ServFail DNS error

Status in Ironic:
  Invalid
Status in network-manager package in Ubuntu:
  Invalid

Bug description:
  Description of problem:
  When ironic (undercloud) is not able to get reverse DNS entry for IP assigned 
to br-ctlplane (doesn't even receive NXDomain error message in time, e.g. DNS 
server is misconfigured, connectivity issues, ...), all ironic commands take 
very long to execute (they will time out, but they still succeed).

  [undercloud]: $ time ironic-node list
  
+--+--+---+-++-+
  | UUID | Name | Instance UUID | Power State | 
Provisioning State | Maintenance |
  
+--+--+---+-++-+
  ...
  real0m55.383s
  user0m0.248s
  sys 0m0.043s

  Version-Release number of selected component (if applicable):
  Tested on OSP director 8

  How reproducible (example with IP 10.100.100.1):
  [undercloud]: $ ip a
  ...
  7: br-ctlplane:  mtu 1500 qdisc noqueue 
state UNKNOWN 
  link/ether  brd ff:ff:ff:ff:ff:ff
  inet 10.100.100.1/24 brd 10.100.100.255 scope global br-ctlplane
 valid_lft forever preferred_lft forever
  ...

  Configure your DNS server to not respond (even with NXDOMAIN) for
  10.100.100.1:

  [undercloud]: $ time host 10.100.100.1
  ;; connection timed out; no servers could be reached
  real0m14.005s
  user0m0.003s
  sys 0m0.003s

  [undercloud]: $ time dig -x 10.100.100.1
  ...
  ;; global options: +cmd
  ;; Got answer:
  ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 20304
  ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1
  ;; OPT PSEUDOSECTION:
  ; EDNS: version: 0, flags:; udp: 4096
  ;; QUESTION SECTION:
  ...
  ;; connection timed out; no servers could be reached
  real0m21.007s
  user0m0.003s
  sys 0m0.004s

  [undercloud]: $ time nslookup 10.100.100.1
  ;; connection timed out; trying next origin
  ;; connection timed out; trying next origin
  ;; Got SERVFAIL reply from XYZ, trying next server
  ;; connection timed out; trying next origin
  ;; connection timed out; trying next origin
  ;; connection timed out; no servers could be reached
  real0m50.008s
  user0m0.002s
  sys 0m0.009

  Actual results:
  Ironic commands can take 20-60 seconds per one in this case

  Expected results:
  Ironic should have mechanism to deal with this, commands shouldn't take tens 
of seconds rather than milliseconds:
  [undercloud]: $ time ironic-node list
  
+--+--+---+-++-+
  | UUID | Name | Instance UUID | Power State | 
Provisioning State | Maintenance |
  
+--+--+---+-++-+
  ...
  real0m0.393s
  user0m0.244s
  sys 0m0.041s

Note that this issue is likely to be fixed in Mitaka.
