Github user ustcweizhou commented on the pull request: https://github.com/apache/cloudstack/pull/930#issuecomment-148293227 @karuturi I think we can remove the loop only if we does not support Ubuntu 12.04 and CentOS 6.X any more. This PR LGTM if we assume the virtio port will work at the end (I mean in 30 times try). Because the /var/cache/cloud/cmdline exists after starting, so the loop will terminate.
