Unsure if this is an issue with nova or with the cloud image itself.
Assigning to the disto.openstack PL for review

[Ghada Khalil (gkhalil)]

@Yong Hu, can you please recommend a release tag and priority for this? Will it be marked for resolution in stx.4.0?

Hi Pengpeng,

Can you reproduce it again, is it one time issue?
I doubt it is set up issue, you may need wait for a while after ubuntu VM created.
There is a similar issue we discussed last year, FYI.

Thanks!

As per discussion with Yang Liu, the test PL, we agreed to close this LP as Not Reproducible. The issue was only reported once. Since we are moving to Ussuri, there is no point in keeping this open.
