[one-users] RVM in OpenNebula

[Daniel Molina Aranda]

Hi,

We have found a bug that sometimes shows up when trying to migrate a virtual
machine two times to the same host in a short piece of time. We have
reproduced the error sending this command:

onevm migrate 0 0 1

Rangababu and Székelyi, is this maybe the root cause for your situation?

This bug will be fixed in the next maintenance release.

Regards.
