------=_Part_1673666_1102566962.1417690140159 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, I would like to add access the ovirt-user-portal webui for external users. Could I seperate this from ovirt-portal-server? I just wondering, maybe that is a possible way if I create an virtual machine for user-portal with external IP address and the users could connect to them. I don't want to add access to the whole portal server directly. Is it possible?

[QE][ACTION REQUIRED] oVirt 3.6.0 status
by Sandro Bonazzola 04 Dec '14

04 Dec '14

Hi, Release criteria discussion has been closed with last week oVirt sync meeting [1]. Release management for 3.6.0 [2] will soon be updated with the accepted changes in release criteria. The remaining key milestones for this release must now be scheduled. For reference, external project schedules we're tracking are: Fedora 21: 2014-12-09 Fedora 22: 2015-XX-XX GlusterFS 3.7: 2015-04-29 OpenStack Kilo: 2015-04-30 Two different proposals have been made about above scheduling [3]: 1) extend the cycle to 10 months for allowing to include a large feature set 2) reduce the cycle to less than 6 months and split features over 3.6 and 3.7 Feature proposed for 3.6.0 must now be collected in the 3.6 Google doc [4] and reviewed by maintainers. The tracker bug for 3.6.0 [5] currently shows no blockers. There are 453 bugs [6] targeted to 3.6.0. Excluding node and documentation bugs we have 430 bugs [7] targeted to 3.6.0.

How to stick VM to hosts?
by Arman Khalatyan 04 Dec '14

04 Dec '14

Hello, I have 2 VMs with the negative Affinity. I am looking some way to force the VMs running on different selected hosts. Assuming I have hosts c1-c8: Can I tell VM to run on c1-c8 but not c2 and c4? Thanks, Arman. *********************************************************** Dr. Arman Khalatyan eScience -SuperComputing Leibniz-Institut für Astrophysik Potsdam (AIP) An der Sternwarte 16, 14482 Potsdam, Germany ***********************************************************

Storage domain issue
by Koen Vanoppen 04 Dec '14

04 Dec '14

Dear All, After we updated our hypervisors to : vdsm-4.16.7-1.gitdb83943.el6.x86_64 vdsm-python-4.16.7-1.gitdb83943.el6.noarch vdsm-python-zombiereaper-4.16.7-1.gitdb83943.el6.noarch vdsm-xmlrpc-4.16.7-1.gitdb83943.el6.noarch vdsm-yajsonrpc-4.16.7-1.gitdb83943.el6.noarch vdsm-jsonrpc-4.16.7-1.gitdb83943.el6.noarch vdsm-cli-4.16.7-1.gitdb83943.el6.noarch We don't have access to our storage domain anymore. He jsut doesn't see the disks anymore... I added the vdsm log and engine log. I'm clueless... BEfore he did see the storage domains, now after the system update he doesn't anymore... Thanks in advance, Kind regards, Koen

Re: [ovirt-users] ovirt-guest-agent on windows : what Python env. needed?
by Lev Veyde 04 Dec '14

04 Dec '14

Hi Nicolas, If the agent is compiled with py2exe (and as you got .exe files it means it was compiled with py2exe) then the executables are self contained, and you don't need to install Python separately in each VM. All you need is to download and install VC runtime, which you can download from here: http://www.microsoft.com/en-us/download/details.aspx?id=5582 That should resolve the issue. BTW, we have oVirt WGT (Windows Guest Tools) RPM, with ISO which contains the installer that will install the oVirt Guest Agent (including VC Runtime), as well as drivers etc. automatically for you. Thanks in advance, Lev Veyde. ----- Original Message ----- From: "Sandro Bonazzola" <sbonazzo(a)redhat.com> To: "Lev Veyde" <lveyde(a)redhat.com> Sent: Wednesday, December 3, 2014 1:49:00 PM Subject: Fwd: [ovirt-users] ovirt-guest-agent on windows : what Python env. needed? -------- Messaggio Inoltrato -------- Oggetto: [ovirt-users] ovirt-guest-agent on windows : what Python env. needed?

A: Users(a)ovirt.org <Users(a)ovirt.org> Hello, I read the following page : http://www.ovirt.org/OVirt_Guest_Agent_For_Windows and applied it on a server, and it ran very well. I obtained the two executables, copied them into "program files" according to the doc, along with the .ini as stated here : https://www.mail-archive.com/users@ovirt.org/msg18561.html - the "-install", the start, and the enabling went fine - rebooting the server runs OK too, and the agent is seen by oVirt What I don't understand is the following sentence of https://github.com/oVirt/ovirt-guest-agent/blob/master/ovirt-guest-agent/RE… "Optionally install py2exe if you want to build an executable file which doesn't require Python installation for running" As I don't know python at all, I thought this was building some sort of "self-executable" binary that I could copy-paste into another VM, and do the same install/enable/run. And WITHOUT installing any Python environnement. I'm sorry for such a weak question, but if this is not the case, does that mean I have to install a Pyhton env on each of my windows VMs? BTW, I tried to copy-paste the programfiles/guestagent... into another server, and when running the install, it gives a message [in french, :( ] L'application n'a pas pu démarrer car sa configuration côte-à-côte est incorrecte. That could be translated by : The application could not start because its side-by-side (?) config is incorrect. PS : Time is not anymore at launching windows_vs_linux war, but I just installed the guest agent on 17 _linux_ VMs in 3 minutes... -- Nicolas Ecarnot _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Note that this isn't specific to hosted-engine, it's the same for any migration using engine-backup to backup/restore, therefore there is a link to its page in the top, where this is more detailed.
