Re: [one-users] Run the VM on another data center
Hello again! In the documentation you have sent me I did not find anything related to the migration of a VM from one data centre to another one, but only about managing them from within a data centre. Thanks!

Re: [one-users] Monitor continually cycles through finding machines RUNNING and stat UNKNOWN
It seems that there are more people having this problem and we are taking a look on several ways to fix this. One problem with /var/run is that it is normally owned by root and a process started by oneadmin user can not write there. In the frontend a new directory for OpenNebula pid files is created but in the nodes it does not exist.

When the machines below was enabled, immediately our DNS server is flooded with requests from the host (see a sample below). Our logs show that this has only started happening since the upgrade to 4.4. If we don't get a fix for this we will have to go back to 4.2, which is something I really don't want to do.

[one-users] How to reboot a host without migrating the VMs running on it?
Hi, Is there any recommended way to reboot a host without migrating the VM from it to another host? The issue I have is that I need to reboot all the hosts but as they are running a lot of large Windows images (up 100GB) the logistics of live migration if complicated. Can the image be put into a recommended state and resumes after the host has restarted. I've tried shuting down the VM but this doesn't seem to work. Maybe it is aWindows issue.

I have the same needs for maintenance and performance tunning of my organization system. Suggestions are highly appreciated.

Re: [one-users] Closing OpenNebula 4.4 Cycle, Planning for 4.6
Hi First, we'd like to thank you all the comments and feedback for OpenNebula 4.6. We really appreciate it :) Our goal for 4.6 is two-fold: improve federation module (aka ozones) and improve OpenNebula usability (based on OpenNebula user comments received during the last releases). It's been always difficult to prioritize the new features considering the limited time-frame of a release, so we tried to balance the effort and number of features. The complete list of features is here [1]. About the specific requests in this thread. In 4.6, We are going for: - #2568 Support for RBD Format 2 images - #1727 Patch for one.image.resize to resize image - #1818 Support for IP reservations along with #2545 Decorrelate networks TYPE and IP management - #1696 Add the ability to select datastore for Clone operation as a previous step for #2417 “Move images between datastores”. #2417 requires preserving the ID, so let see if we can easily get both - #2453 Add hostname configuration to contexualization - #2048. Instantiate to persistent - #2648: ACL edit/view wizard - #2649: sunstone, occi, econe, novncserver ability to log to syslog server These issues have been moved to the backlog, with a high priority to consider them for 4.8, complete backlog [2]: - oneacct extended to the webinterface. This is issue #1607, in this release we are going for #1484 (output in csv format of accounting data) - over-committing memory (ram) to VMs just like how you can set over commit in CPU. This is issue #1328 - One feature I would like to see would be a recycle bin this has been merge with #2412 Ability to lock VM from accidental actions - #2560 Re-read oned.conf on reload - #2651 Implement mailbox to prevent vm from running twice. Again thanks for the feedback.

We have identified the issues [1] (bugs + features) we deem important for the release, and we have including in that list the features that didn't make it in OpenNebula 4.4 in the end. As discussed with the OpenNebula Conf attendees (see? you need to come next year ;) ), we want to give our users the chance to shape the roadmap for the upcoming OpenNebula 4.6. We invite you to submit your comments on the roadmap via email (ideally within this thread, but feel free to open a new one if you think it is necessary to discuss any particular topic). This valuable input will be used to shape the short-term roadmap with the features that will be part of the release cycle. The ideal process of the discussion would be for any person interested in discussing a feature request to search first if there is already a similar one in the OpenNebula development portal [2]. If no similar request is found, please open one describing as best as you can what feature you have in mind, and let us know in this mailing list so we know there is interest and we need to shape the roadmap to accommodate it. If you find a similar request, read through the proposed approach and let us know if you agree on it. If not, please put a comment in the feature request explaining your concern, and let us know as well here. We plan to close this discussion next Thursday, 16th, EOB. It goes without saying that the more interest we see on a feature, more priority it will have in the short-term roadmap.

Re: [one-users] How to reboot a host without migrating the VMs running on it?
Probably: poweroff or suspend the VMs, then reboot the host. Once the host is back online just resume the VMs... (double check that any shared FS is properly mounted, specially those with the VM disk images) You can also use --hard in case your VMs are not ACPI aware. Note that suspends saves the VM state.
