Hi, Just This always happens in Essex release. After I take a snapshot of my VM ( I tried Ubuntu 12.04 or CentOS 5.8), VM can't ping its self floating IP; before I take a snapshot though, VM can ping its self floating IP. This looks closely related to https://bugs.launchpad.net/nova/+bug/933640, but still a little different. In 933640, it sounds like VM can't ping its self floating IP regardless whether we take a snapshot or not. Any suggestion to make an easy fix? And what is the root cause of the problem? Thanks, Sam -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack/attachments/20120717/31649b0c/attachment.html>
