Dear All, I'm having problems getting LDAP running, login works, but I'm getting "user is not authorised to perform login" - this is even if i specify the UserRole specifically to the LDAP group the user is in. 2018-05-25 08:56:16,212+01 INFO [org.ovirt.engine.core.sso.utils.AuthenticationUtils] (default task-23) [] User callum@Biomedical Research Computing successfully logged in with scopes: ovirt-app-admin ovirt-app-api ovirt-app-portal ovirt-ext=auth:sequence-priority=~ ovirt-ext=revoke:revoke-all ovirt-ext=token-info:authz-search ovirt-ext=token-info:public-authz-search ovirt-ext=token-info:validate ovirt-ext=token:password-access 2018-05-25 08:56:16,391+01 INFO [org.ovirt.engine.core.bll.aaa.CreateUserSessionCommand] (default task-25) [63e60fe9] Running command: CreateUserSessionCommand internal: false. 2018-05-25 08:56:16,430+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-25) [63e60fe9] EVENT_ID: USER_VDC_LOGIN_FAILED(114), User callum@Biomedical Research Computing connecting from '192.168.65.254' failed to log in<UNKNOWN>. 2018-05-25 08:56:16,430+01 ERROR [org.ovirt.engine.core.aaa.servlet.SsoPostLoginServlet] (default task-25) [] The user callum@Biomedical Research Computing is not authorized to perform login on a side note: is it possible to assign permissions to all members of an LDAP tree where they dont have a common group membership?

I am attempting to upgrade from ovirt-engine 4.1 to 4.2 however yum updates are failing due to dependency conflicts. [root@ovirt-engine yum.repos.d]# yum update "ovirt-*-setup*" Loaded plugins: fastestmirror, versionlock Loading mirror speeds from cached hostfile * ovirt-4.2: mirrors.rit.edu * ovirt-4.2-epel: mirror.steadfast.net sac-gdeploy | 3.0 kB 00:00:00 Resolving Dependencies Error: ovirt-engine-setup-plugin-ovirt-engine conflicts with ovirt-engine-4.1.1.8-1.el7.centos.noarch Is there a way to resolve this? I'm using the instructions located at https://www.ovirt.org/release/4.2.1/#install--upgrade-from-previous-versions

engine-setup fails to upgrade postgresql
by Michael Watters 12 Jun '18

12 Jun '18

After installing the ovirt 4.2 repository and running engine-setup the upgrade script fails with an error as shown below. [ ERROR ] Postgresql client version is '9.5.9', whereas the version on 'localhost' is '9.2.23'. Please use a PostgreSQL server of version '9.5.9'. Please note the following required changes in postgresql.conf on 'localhost': postgresql.conf is usually in /var/lib/pgsql/data, /var/opt/rh/rh-postgresql95/lib/pgsql/data, or somewhere under /etc/postgresql* . You have to restart PostgreSQL after making these changes. Engine database host []: The setup script is supposed to take care of this automatically however it fails before even attempting to upgrade postgres. Does anybody know how to work around this?

Using this as reference: https://www.ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluste… Assuming you want to increase the number of hosts from 3 to 5 or 9. How do you add more hosts? What is best practice & any gotcha's?

gdeploy hosted engine failed but host says it is up what now?

Hi, Ovirt 4.2.3 I gdeplyed deployed glusterfs which seems to have gone well and then on to the hosted engine... which seemed to be going well, but then the ovirt engine did not come online...

I am pretty new to this setup so would appreciate any steps I can take to move this forward. Thanks Bill

VMs hung after migration
by Kapetanakis Giannis 11 Jun '18

Hi, Please have a look at BZ https://bugzilla.redhat.com/show_bug.cgi?id=1584775 about VM hung problems I have with latest kernels. Problem appeared after upgrading to 4.2.3 but I believe it has only to do with newer kernel and not any part of ovirt/vdsm/libvirt/qemu regards, Giannis

Latency and Bandwidth for Disk level statistics
by Hari Prasanth Loganathan 11 Jun '18

11 Jun '18

Hi Team, I have created a VM using oVirt, which is in UP state now. 1) I opened the guest console using oVirt 2) I want to get the statistics for disk so I tried to create and write some content in the file (say test.txt) in loop to increase the latency and bandwidth in disk. 3) I observed that CPU in VM statistics is increased to 100 % (This is a good news since I expected this also) But when I looked into the disk level statistics using the following API, I observe the data value as '0' always. https://172.30.X.X/ovirt-engine/api/disks/3bc267c0-a797-4e98-8ae9-217671649… { "statistic": [ { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [ { "datum": 0 } ] }, "disk": { "href": "/ovirt-engine/api/disks/3bc267c0-a797-4e98-8ae9-217671649287", "id": "3bc267c0-a797-4e98-8ae9-217671649287" }, "name": "data.current.read", "description": "Read data rate", "href": "/ovirt-engine/api/disks/3bc267c0-a797-4e98-8ae9-217671649287/statistics/33b9212b-f9cb-3fd0-b364-248fb61e1272", "id": "33b9212b-f9cb-3fd0-b364-248fb61e1272" }, { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [ { "datum": 0 } ] }, "disk": { "href": "/ovirt-engine/api/disks/3bc267c0-a797-4e98-8ae9-217671649287", "id": "3bc267c0-a797-4e98-8ae9-217671649287" }, "name": "data.current.write", "description": "Write data rate", "href": "/ovirt-engine/api/disks/3bc267c0-a797-4e98-8ae9-217671649287/statistics/2f23addd-4ebd-3d82-a449-c28778bc33eb", "id": "2f23addd-4ebd-3d82-a449-c28778bc33eb" } ] } *How can I increase the disk statistics using the VM Guest console?* *Any help is much appreciated.* Thanks, Hari
