[one-users] What are the causes let OpenNebula thinks VM is POWEROFF and how to recover?
Hi Everyone, Anyone had ever encounter an issue about VM stat changes to POWEROFF a few minutes (2 ~ 3 minutes) after RUNNING? The actual problem is that the POWEROFF stat is incorrect as the VM is actually running on the computing node. If you try to boot it back, it will failed as that instance is already running on the same computing node. Is it a bug of OpenNebula? Any suggestions to get it recovered?

Re: [one-users] VNC and serial console
FYI. We added virtual serial console feature on our private cloud via adding and modifying a few back-end scripts and UI change a little bit.

[one-users] web UI does not work for zone/vDC if sunstone server is behind a reverse proxy server
After I setup a proxy server (ngnix) before sunstone server on master.
From Sunstone UI (192.168.100.10), I can not change zone to zone1.
Other functions work well from sunstone UI, but changing zone.

If I remove the proxy server, and access directly to sunstone

Re: [one-users] Hostname missing from context
If you look into those init scripts (under /etc/one-context.d) you will figure out the details. In my context setting (4.4.1), I have both SET_HOSTNAME and DNS_HOSTNAM and it works well.

Re: [one-users] can user's RAM quota acount only running/active VMs?
Thank you all very much for the replies! Gene On 14-05-13 06:37 PM, Ruben S. Montero wrote: Yes, there maybe a problem. There won't be nothing to stop the scheduler from allocating the VM if it's resumed. That's the reason for accounting the capacity even if you are not actually using it, you'll be granted with it as soon you request it (and its available). So you may be not making a complete use of the resource them but you have a reservation for them, especially for SUSPENDED/POWER OFF. But also for HOLD, PENDING, STOP, that will potentially interfere with other users when the VM is resumed. Now we could check the quota when the VM is moved to PENDING. For example, OpenNebula won't let you resume the VM. However, the other quotas should be also modified to follow the same convention. For example, number of IP's leased from a network. The main problem I see here is that would be conflicting with other metrics like (number of VMs). If we only limit ACTIVE VMs a DoS attack could be done easily by creating VMs in STOP (e.g. size of checkpoint files is implicitly controlled by the MEMORY quota). If we preserve the quota as in 4.6, then the MEMORY quota for ACTIVE VMs wouldn't be useful. Maybe is not fair in all cases (I believe that only stop VMs are a problem, and that operation is not exposed for the end-users, i.e. cloud view ) but it is consistent for all the quotas...
