i use the no.2 route
2. Apply the patch included in the link. You can do something like:
pushd /usr/lib64/python2.6/site-packages/eventlet
curl https://bitbucket-assetroot.s3.amazonaws.com/which_linden/eventlet/20110214/77/greenpipe-wrap.patch | patch
popd

还是有问题：
Error nova.compute.manage instance 1: Failed to spawn
Command: sudo iptables-save -t filter
Exit code: 1
Stdout: ' '
Stderr: 'sudo: no tty present and no askpass program specified\n'

像连接中的做了一下 https://bugs.launchpad.net/glance/+bug/702722

换了一个error，日。。。
Error nova.exception [-] Uncaught exception
Command: sudo iptables-save -t filter
Exit code: 1
Stdout: ' '
Stderr : 'sudo: sorry, you must have a tty tu run sudo\n'

啥意思哟。。。
