Hi Folks ! I am looking for a documentation for ovirt-engine-sdk-python-4.1 but could not find anything yet. Looks like there are many changes compared to 4.0. Can anyone help me about how to clone a VM from a snapshot using the latest sdk ? Thank you ! -- Niyazi Elvan

Graphics are turned upside down when install QXL in Windows
by Karli Sjöberg 08 Mar '17

08 Mar '17

Heya! Just thought that I´d report something hilarious:) After installing the QXL driver in Windows 7 and 2008R2, in the SPICE HTML5 browser client, all of the graphics are turned 180 degrees. It´s not that the entire screen is flipped either, but all of the individual elements are. E.g. the trashcan that should be in the top right corner is now located in the bottom right, flipped upside down with the text "above" it and text also flipped. Opening an explorer windows still has the location and search bar at the top, with location bar first and search bar to the right, as it should be, but with the graphics turned upside down, plus that the text is still printed from left to right, but upside down. And the "favorites" pane is still located to the left but listed from bottom the top, Windows has never looked this funny:) A picture says a thousand words. Behold! http://imgur.com/a/32P12 The native client displays as it should. Just letting you know. /K

oVirt Nodes Monitoring
by FERNANDO FREDIANI 08 Mar '17

08 Mar '17

Hi. How do you guys monitor your hosts with Zabbix ? I see the oVirt Nodes have snmpd service installed and could be used for basic things but ideally, for Zabbix is good to use its agent. What would be the best way to install its zabbix-agent package and make it persistent ? Add its repository to the oVirt-Node in /etc/yum.repos.d/ and install it with yum or install using a .rpm directly ? Thanks Fernando

This is a multi-part message in MIME format. --------------AB1791EDE4D5CAFD0D43066B Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Hello. I'm running oVirt-Node *4.1.0--0.20170201.0+1* on my hosts and tried a normal upgrade. It detected it has to upgrade to *4.1.1-0.3.rc1.20170303133657.git20d3594.el7.centos* from the ovirt-4.1-pre repository. The upgrade finished with the following problems: ...

iscsi failover MD3820i
by Marcin Kruk 08 Mar '17

08 Mar '17

Hello I have got Dell MD3820i and four interfaces which was connected to the hostst via switches. But there is only one IP which I can set during the configuration of iSCSI RHV storage. Everything has been fine until I pluged off cable from the storage NIC interface with IP configured in the RHV iSCSI section. Now VDSMD got problem because it tries to connect via iscsiadm with exact IP and does not use the configuration from the /var/lib/iscsi/, where are tree extra paths to achive the LUN. In multipath -ll I see an active path, of course with the second storage interface IP systemctl status vdsmd: CGroup: /system.slice/vdsmd.service ├─4975 /usr/bin/python /usr/share/vdsm/vdsm ├─5558 /usr/bin/sudo -n /usr/sbin/iscsiadm -m node -T iqn.1984-05.com.dell:powervault.md3800i.600a098000ae589c000000005893ade2 -I default -p 192... └─5559 /usr/sbin/iscsiadm -m node -T iqn.1984-05.com.dell:powervault.md3800i.600a098000ae589c000000005893ade2 -I default -p 192.168.130.101 32...

ovirt don't give "initiator name" to cinder when I'm launching a VM with a cinder volume
by herve 08 Mar '17

08 Mar '17

dear ovirt user community, I can't sort out an ovirt issue I got with cinder for weeks, I hope someone could give me a clue... From mi ovirt manager 4.1, I can create and delete a cinder volume or attach and detach a cider vomume from an ovirt VM. The problem is I never had been able to launch an ovirt VM with a cinder volume attached to it. I just got a simple message from ovir web gui: "Failed to run VM centoscinder (User: admin@internal-authz)". what i am using is a RDO newton release of openstack. the backend of cinder is a local lvm, and the openstack VMs can use the cinder volumes from other compute node. from the ovirt 4.1 fedora 24 server: [root@rhevf24 ~]# rpm -qa | grep ovirt-engine-4 ovirt-engine-4.1.0.4-1.fc24.noarch ovirt-engine-setup-plugin-ovirt-engine-4.1.0.4-1.fc24.noarch [root@rhevf24 ~]# from the ovirt server , through the iscsiadm command, I can see for example the 2 disks attached to 2 diffents openstack instances, but not the one I just created from ovirt which is attached to nothing , from the openstack rdo point of view. [root@rhevf24 iscsi]# iscsiadm -m discovery -t sendtargets -p 192.168.122.36 192.168.122.36:3260,1 iqn.2010-10.org.openstack:volume-f4c6c55c-e383-4781-8d24-d41b55870d29 192.168.122.36:3260,1 iqn.2010-10.org.openstack:volume-58844340-741e-45da-9aa7-b0ed08391df3 as I said previously From ovirt I can create /delete in cinder and attach/detach volumes to ovirt VMs I don't get any troubles with that. ---- in ovirt engine.log almost nothing , except it can't aquire lock.. but in openstack cinder, and with tcpdump I get more informations. tcpdump give me when ovirt intent the iscsi connection something like: json.key == "os-initialize_connection" {. "os-initialize_connection" : {. "connector" : { }, },} and I get from "tail -f /var/log/cinder/volume.log" : 2017-03-07 16:45:06.889 3856 ERROR cinder.volume.targets.iscsi [req-b6d39a14-f9ea-4552-91e7-5db811217b1e dd1dd33789274fb7ba228c75a07c0e94 0f68893965dd4f5dafd319cbffb33bb4 - default default] The volume driver requires the iSCSI initiator name in the connector. ... ... 2017-03-07 16:45:06.891 3856 ERROR oslo_messaging.rpc.server InvalidInput: Invalid input received: Connector doesn't have required information: initiator So it looks like I didn't get or I can't provide the initiator name I want to be connected to. Cinder can't obviously guess which one I want. that's more or less what's the cinder's logs are telling me. I have searched for a long time in internet, it looks like at least since ovirt 3.6, cinder is ont anymore an issue, and can even be integrated with a ceph back end to ovirt... cinder model an client are installed in the ovirt server... Somebody get any clue to tell ma where i made a mistake in the cinder integration with ovirt , which seems to be correct regarding the create/delete attach /detach volume behavior... Thank you Herve

Second node ovirt 4.0 no ovirtmgmt bridge, non-operational issue
by Ian Neilsen 07 Mar '17

07 Mar '17

Hi all I currently have a non-operational second node in my "ovirt 4.0 hosted-engine" installation running on Centos7, kernel 3.10.0-514.10.2.el7.x86_64. When I ran "hosted-engine --deploy" on the second node, it produce the following error(see bottom of email). I now cannot set the second node into operational mode, no matter what I try. I did notice a few things though. #1 - no ovirtmgt bridge was created during hosted-engine deploy; should I create this bridge and retry? #2- vdsmd keep throwing start errors before I ran hosted-engine deploy. I ran vdsm-tool configure --force this seem to fix it. #3 - second node complained of no fencing agent, so I added in a DRAC fence agent and it worked/tested fine. But still not able to go opertional on second node. #4 Ive tried restarting vdsmd, ovirt-ha-agent and ovirt-ha-broker. Both the agent and broker throw error messages.(see bottom of email for errors) Any advice of where to look next, what to fix? ***Hosted-engine --deploy message*** [WARNING] Host left in non-operational state To finish deploying, please: - activate it - restart the hosted-engine high availability services by running on this machine: # service ovirt-ha-agent restart # service ovirt-ha-broker restart [ INFO ] Enabling and starting HA services [ INFO ] Stage: Clean up [ INFO ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20170307062116.conf' [ INFO ] Generating answer file '/etc/ovirt-hosted-engine/answers.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ INFO ] Hosted Engine successfully deployed ***ovirt-ha-agent error message*** ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config ERROR Unable to get vm.conf from OVF_STORE, falling back to initial vm.conf ***ovirt-ha-broker error message*** ovirt-ha-broker ovirt_hosted_engine_ha.broker.notifications.Notifications ERROR Connection unexpectedly closed Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/broker/notifications.py", line 34, in send_email message.as_string()) File "/usr/lib64/python2.7/smtplib.py", line 749, in sendmail self.rset() File "/usr/lib64/python2.7/smtplib.py", line 468, in rsetreturn self.docmd("rset") File "/usr/lib64/python2.7/smtplib.py", line 393, in docmdreturn self.getreply() File "/usr/lib64/python2.7/smtplib.py", line 367, in getreplyraise SMTPServerDisconnected("Connection unexpectedly closed") SMTPServerDisconnected: Connection unexpectedly closed -- Ian Neilsen Mobile: 0424 379 762 Linkedin: http://au.linkedin.com/in/ianneilsen Twitter : ineilsen
