[ovirt-users] Re: VMs hung after migration

[Alejandro Cortina]

Hi Peter,

I have a similar issue. Have you tried downgrading to
kernel-3.10.0-693.21.1.el7.x86_64 ?

Cheers,

Alex

[ovirt-users] oVirt Version 4.2.3.5-1.el7.centos cannot change password from user (Bad Request)

[Alejandro Cortina]

Hi there,

I have created a new user from hosted engine by:

ovirt-aaa-jdbc-tool user add test_user --attribute=description='test user'
--attribute=firstName=test_user
ovirt-aaa-jdbc-tool user password-reset test_user --password=pass:changeme

then I try to login and I get the message:

 *Unable to log in because the password has expired. Change the password to
proceed. *

When I click "Change the password" the browser redirects to:

https://FQDN/ovirt-engine/sso/%s

and I get




*Bad RequestYour browser sent a request that this server could not
understand.*

Last time I tried with 4.2.1 and it was working with no issues.

Cheers,

Alex

[ovirt-users] Re: oVirt reports using Grafana

[Alejandro Cortina]

Hi Shirly,

I went through your instructions just yesterday and they work but some
troubleshooting was needed. This is what I have found:

* When adding the graph I also got syntax errors: '*pq: syntax error at or
near "$"'*, maybe add an "ignore this error" line to the docs would be an
improvement
* I am new to grafana then I could not understand about templating. Took me
a few *trips* to http://docs.grafana.org/reference/templating/ to
understand it. Maybe some simple instructions would make experience better.
* Regarding tremplating:

cluster_name
- fails: SELECT cluster_name FROM v4_2_configuration_history_clusters WHERE
datacenter_id = $datacenter_id
- not fail: SELECT cluster_name FROM v4_2_configuration_history_clusters
WHERE datacenter_id='$datacenter_id'

cluster_id
- fails: SELECT cluster_id FROM v4_2_configuration_history_clusters WHERE
datacenter_id = $datacenter_id
- not fail: SELECT cluster_id FROM v4_2_configuration_history_clusters
WHERE datacenter_id ='$datacenter_id'

there are many more.

* Modifying DB, even DWH views are stable I think it would be better to
instruct to make backup.

Regarding modifying DB, Is it possible to revert these changes?

Thanks!
