Re: [one-users] distributed frontend with raft consensus algorithm
Hi, On Wed, Feb 5, 2014 at 5:31 PM, Sharuzzaman Ahmat Raslan sharuzza...@gmail.com wrote: Hi all, My last interaction with Opennebula is with the version 3.8 In that version, the frontend can only be running by a single node. To have a redundancy, it was advised to have the frontend to be configured using HA tools, such as Red Hat cluster suite. See http://archives.opennebula.org/documentation:archives:rel4.2:oneha I believe that kind of setup is not optimal, as you have to bolt in another subsystem, that could potentially become another head ache to maintain. As alternative to external clustering system, I would like to highlight to the developers the availability of Raft Consensus Algorithm. See http://raftconsensus.github.io/ This algorithm can help to maintain the availability of the frontend, in a fault-tolerant distributed system. With this algorithm, frontend can be run on the VM nodes itself, where at any given time, one of the nodes will act as a frontend for the whole cluster. If that leader node goes down, any other node will step up to become the next leader, and maintaining the availability of the frontend This can help simplify deployment, and reduce the requirement to have a dedicated frontend machine, with another failover machine in standby I hope this idea could be discussed futher, and implemented on the future release of Opennebula. thanks. -- Sharuzzaman Ahmat Raslan Thank you for your suggestion. This may be useful not only for HA, but also for the new OpenNebula federation, where we need to have a master and several slaves. For the first version (that will be included in 4.6) the master will be set manually, but at some point we'll need to think of a way to deal with master selection.

Re: [one-users] oneacct [VirtualMachinePoolAccounting] Internal Error
Hi Stefan, it was in fact a bug/typo, and it has been fixed in master, so it will work fine in OpenNebula 4.6. Anyways, it really doesn't make much difference to have the order by clause or not, so if you simply disable that mysql flag, you'll probably see the results the correct way. cheers, Jaime On Thu, Jan 30, 2014 at 5:50 PM, Carlos Martín Sánchez cmar...@opennebula.org wrote: Hi Stefan, On Tue, Jan 28, 2014 at 5:57 PM, Stefan Kooman ste...@bit.nl wrote: Hi list, Running oneact as oneadmin user I get the following error: oneacct [VirtualMachinePoolAccounting] Internal Error. oned.log shows: Tue Jan 28 17:21:19 2014 [ReM][D]: Req:6624 UID:0 VirtualMachinePoolAccounting invoked, -2, -1, -1 Tue Jan 28 17:21:19 2014 [ONE][E]: SQL command was: SELECT history.body FROM history INNER JOIN vm_pool WHERE vid=oid GROUP BY vid,seq, error 1055 : 'opennebula.history.body' isn't in GROUP BY Tue Jan 28 17:21:19 2014 [ReM][E]: Req:6624 UID:0 VirtualMachinePoolAccounting result FAILURE [VirtualMachinePoolAccounting] Internal Error I don't know for sure it ever worked after I upgraded to onennebula-4.4.

Now that I think about it, we don't really need the group by, and it may probably be a bug and we meant to use ORDER BY [1].

[one-users] Sunstone 403 at login (only with chromium / chrome)
Hi, We have trouble logging in to sunstone with Chromium as a browser. After provoding credentials we end up with a 403 forbidden. Chromium debug console show this: When the default login page gets loaded it gets a 401 Unauthorized trying to GET /jquery.min.map/vendor/4.0. After providing credentials I get a Unexpected error. Status 403. Check the server logs.. Chromium console logs it's getting a 403 during a POST for login (jquery-1.9.1.min.js:5 Script). In firefox everything works as expected. It doesn't matter if I provide correct credentials or not. It always gives a 403. Anyone experienced similar issues? Gr.

Re: [one-users] Computer and network facilities required to set up an office Lab environment to experiment the features/functionalities of OpenNebula platform - Qiubo David Su
Dear OpenNebula Community, I have been using OpenNebula platform to set up IAAS for a while. To better experiment the more advanced features/functionalities offered by the platform, I decide to set up a Lab in the office environment. May any of you specialized in this area help to specify the computer and network facilities required to set up such an environment? i.e. 1) The specification of the server system required *(e.g. what kind of server board? how many CPUs and how many cores per CPU? how much RAM? what size of the Hard Drives? how many NIC ports? how much power of the power supply? what else components required?)*, and how many of this server system required? Is workstation OK? 2) The network will be a LAN in the office environment. What kind of a LAN topology should be set up in order to better experiment the advanced features/functionalities offered by the system? Thank you very much for your help !
