Useless disk statistics API
by Hari Prasanth Loganathan 13 Jun '18

13 Jun '18

Hi Team, I use the following API to get the disk statistics as per the oVirt rest API documentation. http://ovirt.github.io/ovirt-engine-api-model/4.2/#types/disk/links/statist… https://172.30.X.X/ovirt-engine/api/disks/f78c8adf-23f9-4f52-a29b-0de3d8446… { "statistic": [ { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [ { "datum": 0 } ] }, "disk": { "href": "/ovirt-engine/api/disks/f78c8adf-23f9-4f52-a29b-0de3d844652e", "id": "f78c8adf-23f9-4f52-a29b-0de3d844652e" }, "name": "data.current.read", "description": "Read data rate", "href": "/ovirt-engine/api/disks/f78c8adf-23f9-4f52-a29b-0de3d844652e/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/f78c8adf-23f9-4f52-a29b-0de3d844652e", "id": "f78c8adf-23f9-4f52-a29b-0de3d844652e" }, "name": "data.current.write", "description": "Write data rate", "href": "/ovirt-engine/api/disks/f78c8adf-23f9-4f52-a29b-0de3d844652e/statistics/2f23addd-4ebd-3d82-a449-c28778bc33eb", "id": "2f23addd-4ebd-3d82-a449-c28778bc33eb" } ] } Unfortunately, the values are always coming as '0'. *Steps to reproduce :* 1) I logged into the VM console and run the following command to copy the file and I see the write rate is 300mb/sec dd if=/dev/zero of=/dev/null 2) During this time, I am trying to execute this API and receiving as 0 always. Is this API useless? Thanks, Hari

UEFI
by Conrad Jones 12 Jun '18

Does ovirt support UEFI yet ? I saw some code reviews in gerrit. But I couldn't find it in my 4.23 install. I'm guessing it's not finished / released yet ?

Unable to authenticate using AD accounts
by Michael Watters 12 Jun '18

12 Jun '18

I am having an issue getting users to authenticate using the Active Directory backend. I've installed the ovirt-engine-extension-aaa-ldap-setup package and ran ovirt-engine-extension-aaa-ldap-setup to configure everything however users are unable to authenticate. Testing using my own account results in a "credentials incorrect" error as shown below. 2018-06-12 14:16:55,700-04 INFO End of enabled extensions list 2018-06-12 14:16:55,700-04 INFO ======================================================================== 2018-06-12 14:16:55,701-04 INFO ============================== Execution =============================== 2018-06-12 14:16:55,701-04 INFO ======================================================================== 2018-06-12 14:16:55,702-04 INFO Iteration: 0 2018-06-12 14:16:55,704-04 INFO Profile='dartcontainer.com' authn='dartcontainer.com-authn' authz='dartcontainer.com-authz' mapping='null' 2018-06-12 14:16:55,705-04 INFO API: -->Authn.InvokeCommands.AUTHENTICATE_CREDENTIALS profile='dartcontainer.com' user='d861703' 2018-06-12 14:16:55,869-04 INFO API: <--Authn.InvokeCommands.AUTHENTICATE_CREDENTIALS profile='dartcontainer.com' result=CREDENTIALS_INCORRECT 2018-06-12 14:16:55,879-04 SEVERE Authn.Result code is: CREDENTIALS_INCORRECT Is there a way to enable more verbose logging or is there an alternative to using LDAP such as keycloak integration?

Grubx64.efi missing from boot partition
by Hanson Turner 12 Jun '18

12 Jun '18

Hi Guys, We went to physically move a node and have found the node will not boot successfully anymore. The error coming up is :failed to open/ file not found: \EFI\BOOT\grubx64.efi This file is found in \EFI\centos\grubx64.efi. I have copied it to \EFI\BOOT\ and got the machine to boot, however, it has no working networking. Modifying /etc/sysconfig/ifcfg-xyzabz123 appropriately restored networking, however, the node is not able to be resumed/activated. This is probably because the blade reports the following interfaces: eno1, eno2, eno3, eno4 When originally deployed, they were eno1,eno2, eth0, eth1. The engine still sees the host as having the eno+eth combo. Any ideas guys? Thanks!

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?

VMs hung after migration

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

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

Hosted Engine: brick size...is this a bug?
by femi adegoke 11 Jun '18

11 Jun '18

I have now done the oVirt 4.2.3.1 install at least 5 times, no, I don't consider myself any kind of expert. Even though the HE uses less than 10gb of space for some reason the install will fail if the brick is less than 58gb. Why is that? Look at this error: [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Problem while trying to mount target]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Problem while trying to mount target]\". HTTP response code is 400."} The size of the brick was set at 50gb: [lv1] action=create vgname=gluster_vg1 lvname=engine_lv lvtype=thick size=50GB mount=/gluster_bricks/engine Solution: Edit size to 60gb, re-run & voila, all is good. Is this a bug or maybe it's a problem with the way I'm doing things.

Snapshotting Oracle 11g on oVirt
by Vinícius Ferrão 10 Jun '18

10 Jun '18

Hello, I’m planning to install Oracle 11g on a VM inside oVirt. I already knew about the licensing hell of running Oracle 11g on a virtualized environment. The question is about snapshotting Oracle 11gb when the VM is running. Is this supported? For example, on VMware and XenServer there’s the quiesce option to make the filesystem, with a little help from the guest agent, to be in an a good state for snapshots. But in oVirt, how this is handled? If supported, which operating systems are compatible with the feature? Thanks,

Ovirt 4.2 SDK - Way to add files with CloudInit()
by atripathi＠hypergrid.com 10 Jun '18

10 Jun '18

Hi. I am using Ovirt 4.2 Java SDK. Quick query, can we add additional files to ~openstack/content and modify meta_data.json to point these files. I can see we can add files to .cloudInit(cloudInit().files(files)) But API ignores it .. I checked it on /var/log/ovirt-engine/engine.log as well as the img created and attached with VM Reference - Cloudinit version support such files cat meta_data.json {"files": [{"path": "/etc/injected_files", "content_path": "/content/0000"}, {"path": "/etc/trove/conf.d/guest_info.conf", "content_path": "/content/0001"}, {"path": "/etc/trove/conf.d/trove-guestagent.conf", "content_path": "/content/0002"}], reference https://bugs.launchpad.net/cloud-init/+bug/1602373

After minor upgrade oVirt Node to 4.2.3 can't start Virtual machine
by stefan.palecek＠x112.cz 10 Jun '18

10 Jun '18

Dear all, after upgrade oVirt Node to latest 4.2.3 I can't start any virtual machine with network interface. VM machine without network interface starts normally. Exactly the same situation is on freshly installed oVirt node machine with different hardware. I use openvswitch on both machines. After some searching I found out that there are the same version of openvswitch(2.9.0-3) on old and new version of oVirt node but different versions of libvirt(3.9.0-14 vs 3.2.0-14) Error message of libvirtd when the VM machine fail to start: VM OPNsense is down with error. Exit message: Unable to add bridge ovirtmgmt port vnet0: Operation not supported. Any suggestions? Thank you. Stefan

Upgrading ovirt 4.1 -> ovirt 4.2
by Alex K 10 Jun '18

10 Jun '18

Hi all, If one cannot perform a minor upgrade of ovirt 4.1 (due to surprisingly missing repos...) is it ok to ignore this and proceed directly to major upgrade to ovirt 4.2? I don't like very much the idea as I don't know to what surprises I will have considering that this is production. What is your experience/suggestions? Alex

ovirt and gluster network config
by william.dossett＠gmail.com 09 Jun '18

09 Jun '18

Hi, I have my 5 ovirt nodes up and running and starting to move forward with actual ovirt and gluster setup. I am using gdeploy for deployment. the play book fails saying /dev/sdb is blacklisted by filter? I am following the blog up and running on the ovirt site. It mentioned adding # disable multipath [script2] action=execute file=/usr/share/ansible/gdeploy/scripts/disable-multipath.sh to get it to work, but it does not work. The script 3 section after this does have the file=/usr/share/gdeploy/scripts/blacklist_all_disks.sh in it. What can I do to get past this? Also not sure if I should be modifying the script/play as I don't really want an arbitrator host - if I have 5 real hosts all with the same storage in them? (10TB in each) and it only account for 3 hosts, can I add the other two later or should I try to modify the playbook to include these initially? I am sure I will be setting this up several times before I get it right, but at the moment I can't get past this error. Any help would really be appreciated! Thanks
