Message #24055
Re: VM Issues on Grizzly Install on Ubuntu 12.04
Hi Darragh,
Even I am facing the same issue of request getting timed out and even
updates getting hanged up for very long time. I followed your step of
reducing the MTU size from 1500 to 1454 and now everything works fine. I
tried this on Ubuntu instances.
This seems to be an issue with the Grizzly release. I had already started
email-thread earlier for this but was unable to find the root cause. Here
is the link to it:-
https://lists.launchpad.net/openstack/msg23993.html
Thank you for your suggestion of reducing the MTU size as it solved the
problem. You must file a bug for this so that this issue can be tracked.
Thanks and Regards
Rahul Sharma
