Re: [ovirt-users] Confused by logical networks

Ah yes, you're correct.

I was using the physical host as a GW so that the VMs on the logical 
network would have an access point to outside (like the CentOS 
repositories).


Anyways, I found the cause of my confusion in the end. The switch was 
not properly set up (*ahemm* forgot to save configuration).


3 thumbs up for oVirt showing the LLDP-info of the switch :-)

And the fact that despite having to reinstall essentially everything 
oVirt from scratch (due to failed upgrade), the VMs were just a matter 
if import. Splendid work!

Re: [ovirt-users] oVirt 4.2 WebUI Plugin API Docs?

[Zip]

Hi Alexander,

If I try the following:





var api = parent.pluginApi('HelloWorld');
api.register({
UiInit: function () {
api.addMainTab('FooTab','xtab123','http://foo.com/');
}
});
api.ready();





I get the error in my browser console:

Sun Feb 25 00:03:56 GMT-600 2018
org.ovirt.engine.ui.webadmin.plugin.PluginManager SEVERE: Exception caught
while invoking event handler function [UiInit] for plugin [HelloWorld]:
Error: java.lang.IndexOutOfBoundsException webadmin:1:13517
 

Sun Feb 25 00:03:56 GMT-600 2018
org.ovirt.engine.ui.webadmin.plugin.PluginManager WARNING: Plugin
[HelloWorld] removed from service due to failure


However if I remove the line:

 api.addMainTab('FooTab','xtab123','http://foo.com/Œ);

And replace it with something simple like:

alert(ŒTest 123¹);

There are no errors and the alert fires as it should.


Any ideas of what I might be missing?

I am running oVirt 4.2.1 on CentOS ­ Hosted Engine setup with 1 host for
testing.

Thanks

Re: [ovirt-users] After upgrade to 4.2 some VM won't start

So if you create new VM and attach the same disk to it, it will run without 
issues ?

Is there a way to do some kind of diff between the new and the old VM settings

[ovirt-users] API endpoint for a VM to fetch metadata about itself

[Geoff Sweet]

Is there an API endpoint that VM's can query to discover it's oVirt
metadata? Something similar to AWS's http://169.254.169.254/latest/
meta-data/ query in EC2? I'm trying to stitch a lot of automation workflow
together and so far I have had great luck with oVirt. But the next small
hurdle is to figure out how all the post-install setup stuff can figure out
who the VM is so it can the appropriate configurations.

Thanks!

Re: [ovirt-users] rebooting hypervisors from time to time

[Mahdi Adnan]

Hi,

The log does't indicate HV reboot, and i see lots of errors in the logs.
During the reboot, what happened to the VM inside of the HV ? migrated ? paused 
? what about the system's logs ? does it indicate a graceful shutdown ?

Thanks for the reply,

I've attached all the logs from yesterday, reboot has happened during the day 
but this is not the first time and this is not the only one hypervisor.

[ovirt-users] Hosted Engine VM not imported

[Alessandro De Salvo]

Hi,

I have just migrated my dev cluster to the latest master, reinstalling 
the engine VM and reimporting from a previous backup. I'm trying with 
4.3.0-0.0.master.20180222192611.git01e6ace.el7.centos


I had a few problems:

- the documentation seems to be outdated, and I just find by searching 
the archives that it's needed to add the two (undocumented) options 
--he-remove-storage-vm --he-remove-hosts


- despite the fact I selected "No" to running the engine-setup command 
in the VM (the ovirt appliance), the engine-setup is executed when 
running hosted-engine --deploy, and as a result the procedure does not 
stop allowing to reload the db backup. The only way I found was to put 
the hosted-engine in global maintenance mode, stop the ovirt-engine, do 
an engine-cleanup and reload the db, then it's possible to add the first 
host in the GUI, but must be done manually


- after it's all done, I can see the hosted_storage is imported, but the 
HostedEngine is not imported, and in the Events I see messages like this:


VDSM atlas-svc-18 command GetVolumeInfoVDS failed: Image path does not 
exist or cannot be accessed/created: 
(u'/rhev/data-center/mnt/glusterSD/atlas-fsserv-07.roma1.infn.it:_atlas-engine-02/f02d7d5d-1459-48b8-bf27-4225cdfdce23/images/c815ec3f-6e31-4b08-81be-e515e803edce',)


   the path here is clearly wrong, it should be 
/rhev/data-center/mnt/glusterSD/atlas-fsserv-07.roma1.infn.it:_atlas-engine-02/f02d7d5d-1459-48b8-bf27-4225cdfdce23/images/b7bc6468-438c-47e7-b7a4-7ed06b786da0/c815ec3f-6e31-4b08-81be-e515e803edce, 
and I see the hosted_engine.conf in the shared storage has it correctly 
set as vm_disk_id=b7bc6468-438c-47e7-b7a4-7ed06b786da0.



Any hint on what is not allowing the HostedEngine to be imported? I 
didn't find a way to add other hosted engine nodes if the HE VM is not 
imported in the cluster, like we were used in the past with the CLI 
using hosted-engine --deploy on multiple hosts.


Thanks for any help,


    Alessandro
