Here's my problem : I have one VM (called Debian) running on a specific host (pc003.lan). I try to migrate it to another host (pc001.lan) but the migration fails. As a result, the VM is still running on pc003 and the number of running VMs on this host is still the same; but I can see one more VM running on the host pc001. It does the same thing with other VMs (mavm1, mavm2, mavm3, Debian2). At the end, the administration portal tells me I have 7VMs running on host pc001, 4 on pc002 and 3 on pc001; I have only 7 VMs , not 14. From now, some errors keep showing up in the log (see attachment). It says that migrations are still running but I cannot cancel them in the administration portal and they never stop/succeed/fail. This problem occurred some time after I enabled quotas in the Datacenter but I don't know if it's related in any way. If I reboot pc001, the number of running VM is reset to 0, but any attempt to migrate a VM to this host does the same thing again. Also, restarting the engine did not fix this issue.

Here's the link again: https://bugzilla.redhat.com/show_bug.cgi?id=1067096#c0 this can be fixed via engine config, but is not supposed to be needed, as vdsm is supposed to have vdsm/dsaversion.py.in:'supportedENGINEs': ['3.0', '3.1', '3.2', '3.3', '3.4'], danken/eli - thoughts?

When I try to change compatibility version at the datacenter level it behaves as expected, i.e. warns me to change the cluster level first. I see a matching log entry in the engine log. However when I try to change the compatibility version at the cluster level the edit cluster dialog box just hangs there. There are no log entries in the engine log. The dialog box goes away when I click cancel. If I select 3.2 or 3.3 and click OK nothing happens. This occurs either during normal running or with hosts in maintenance mode. I would like to change to 3.3. Can you direct me to the sql table or cmd line by any chance. Is this a known problem or something specific to my special setup.

[Users] Request for Wiki - dates
Hi, As most are aware, there's a lot of information on the Ovirt Wiki that's out of date. In spite of our best efforts, that will probably always be true - it's the nature of Wikis. When I look for information on our Wiki, I never know where the most current information is. I think it would be really helpful if someplace on each Wiki page was a useful date to let us know the currency of the info. Probably the most useful date is last-modified, although creation date might also be useful. Maybe we could even map/display the date to the version number of whatever the current stable release was at the time for context (sometimes the content of a page calls out a particular version it's addressing, but a lot of the time it does not). Just as an example, I want to find out about migrating my existing configuration to self-hosted, using 3.4 RC2. A google search shows the following links (in order shown): http://www.ovirt.org/Features/Self_Hosted_Engine http://www.ovirt.org/Migrate_to_Hosted_Engine http://www.ovirt.org/Hosted_Engine_Howto ... I'm sure the Features page is ancient at this point. It's hard to tell about the 2nd page. Of course the date a page was last modified doesn't directly indicate how correct/current the information is, but there's a correlation. Knowing the date would be useful in making a judgment. It might even help the task of identifying and cleaning up obsolete pages. Easy to do? -Bob ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Thanks, Bob Hi Bob, first of all F20 is not fully supported for the engine due to the JBoss version it uses. As for your questions, as any admin will tell you fresh start is usually much better than keeping old files and configurations which may or may not effect what you're trying to install. Since you're about to free a server to become a hypervisor, you can use one of your other hypervisors as the first hosted engine node. The current engine machine is not a hypervisor (missing vdsm, and probably other packages) so you'll need to add it as a host anyway to your hosted engine setup eventually. Having said that, you can try going your own way. This is something which may be technically possible nut we did not try or tested it before.

Re: [Users] adding scripts
if you are trying to hook into UI-specific events, it sounds like you will need to write an oVirt UI Plugin [1] in order to do that. However, I believe that the oVirt UI Plugins infrastructure doesn't support hooking to events such as tab x was selected and/or button b was clicked. It does allow you to add new (custom) tabs/sub-tabs/buttons of your own, and there is a chance that it allows you to hook into events such as 'row x was selected in the grid'. @Vojtech will know better. Vojtech? if you are trying to hook into engine events (e.g. you want to run a script every time a VM is started in oVirt, no matter if the user started it by clicking the 'run' button in the oVirt- engine webadmin, or invoked a REST API request, or an SDK command), then it will require some sort of an engine-plugin infrastructure that we don't have at the moment AFAIK. there is a chance that for some of the events you will be able to utilize the VDSM hooks (at the Host level) [2].

I do not really understand why we have this recurrent Engine bug, of ignoring supportedENGINEs; I think Yaniv does. i recall asking for detailed explanation for why do we have 3 different restrictions , one for supportedEngines, one for the allowed vdsm versions, and one for the cluster level? if vdsm version is supported why isn't it in engine's capabilities yet? because its a vdsm version which was released after that engine was released, hence the vdsm package has to declare its supporting the old engine. so its an hack to allow users to add beta vdsm version to new engine release?.. sounds like that no. its to add the next release of vdsm to a previously released engine. but that's not supposed to be an issue, since its supposed to already report the previous version of engine (which it does) please reopen if it reproduced the issue was verified in https://bugzilla.redhat.com/show_bug.cgi?id=1016461, please reopen if it still appears I do have an issue still with this. When I try to change compatibility version at the datacenter level it behaves as expected, i.e. warns me to change the cluster level first. I see a matching log entry in the engine log. However when I try to change the compatibility version at the cluster level the edit cluster dialog box just hangs there. There are no log entries in the engine log. The dialog box goes away when I click cancel. If I select 3.2 or 3.3 and click OK nothing happens. This occurs either during normal running or with hosts in maintenance mode. I would like to change to 3.3. Can you direct me to the sql table or cmd line by any chance. do not hack the db for such a change, you may skip important upgrade logic/validation. Is this a known problem or something specific to my special setup. Actually my setup is pretty plain, see below or original post in this thread. sounds like a bug, at least for not telling you what is the error. omer - thoughts?

There are users that would like to tell how much traffic each vnic of
each VM has consumed in a period of time. Currently, we report only
bitrate as a percetage of an estimated vnic speed. Integrating this
value over time is inefficent and error prone.
I suggest to have all the stack (Vdsm, Engine, dwh) report the
actually-trasmitted (and actually-received) byte count on each vnic, as
well as the time when the sample was taken.
Currently, Vdsm reports
'eth0': {'rxDropped': '0',
'rxErrors': '0',
'rxRate': '8.0',
'speed': '1000',
'state': 'up',
'txDropped': '0',
'txErrors': '0',
'txRate': '10.0'},
but it should add rxKiBytes, txKiBytes and time to the frill.
GUI could still calculate the rate for illustration, based on the raw
trasmission and the sample time.
Until we break backward compatibility, we'd keep reporting the flaky
rxRate/txRate, too.
I can think of only two problems with this approach: Linux byte counters
would
eventually reset when they overflow. This is currently hidden by Vdsm, but
with
the suggested change, would have to be handled by higher levels of the
stack.
A similar problem appears on migration: the counters would reset and Engine
would need to know how to keep up the accounting properly.
I've opened
Bug 1066570 - [RFE] Report actual rx_byte instead of a false rxRate
to track this request of mine.
For the reconrd, I'm told that there is a very similar need for
reporting accumulated guest CPU cycle IO operations consuption.
Martin, do we already have BZs for the other two use cases?
No.
Please open an RFE for ovirt on these use cases.
