Limitation in using Ovirt SSO Token
by Hari Prasanth Loganathan 08 Mar '18

08 Mar '18

Hi Team, I would like to know, Is there any limitation in using the same sso token for multiple request. I observe that when I use the same sso token for more than 900 HTTP Rest request, the application went down. Is there any limitation in using same SSO token? I could see that my status is showing as ACTIVE and memory and CPU seem fine. Still, the oVirt is not reachable and I need to restart it to access again. sudo systemctl status ovirt-engine.service -l ● ovirt-engine.service - oVirt Engine Loaded: loaded (/usr/lib/systemd/system/ovirt-engine.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2018-03-08 19:15:10 IST; 30s ago Main PID: 10370 (ovirt-engine.py) CGroup: /system.slice/ovirt-engine.service ├─10370 /usr/bin/python /usr/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py --redirect-output --systemd=notify start └─10423 ovirt-engine -server -XX:+TieredCompilation -Xms5961M -Xmx5961M -Djava.awt.headless=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djsse.enableSNIExtension=false -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/ovirt-engine/dump -Djava.util.logging.manager=org.jboss.logmanager -Dlogging.configuration=file:///var/lib/ovirt-engine/jboss_runtime/config/ovirt-engine-logging.properties -Dorg.jboss.resolver.warning=true -Djboss.modules.system.pkgs=org.jboss.byteman -Djboss.server.default.config=ovirt-engine -Djboss.home.dir=/usr/share/ovirt-engine-wildfly -Djboss.server.base.dir=/usr/share/ovirt-engine -Djboss.server.data.dir=/var/lib/ovirt-engine -Djboss.server.log.dir=/var/log/ovirt-engine -Djboss.server.config.dir=/var/lib/ovirt-engine/jboss_runtime/config -Djboss.server.temp.dir=/var/lib/ovirt-engine/jboss_runtime/tmp -Djboss.controller.temp.dir=/var/lib/ovirt-engine/jboss_runtime/tmp -jar /usr/share/ovirt-engine-wildfly/jboss-modules.jar -mp /usr/share/ovirt-engine/modules/common:/usr/share/ovirt-engine-extension-aaa-jdbc/modules:/usr/share/ovirt-engine-wildfly/modules -jaxpmodule javax.xml.jaxp-provider org.jboss.as.standalone -c ovirt-engine.xml Mar 08 19:15:10 ovirtengine.localdomain systemd[1]: Starting oVirt Engine...

ovirt 4.2 gluster configuration
by Edoardo Mazza 08 Mar '18

08 Mar '18

Hi all, Scenario: 3 nodes each with 3 interfaces: 1 for management, 1 for gluster, 1 for VMs Management interface has it own name and its own ip (es. name = ov1, ip= 192.168.1.1/24), the same is for gluster interface which has its own name and its own ip (es. name = gluster1, ip= 192.168.2.1/24). When configuring bricks from Ovirt Management tools I get the error: "no uuid for the name ov1". Network for gluster communication has been defined on network/interface gluster1. What's wrong with this configuration? Thanks in advance. Edoardo

Pre-snapshot scripts to run before live snapshot
by Gianluca Cecchi 08 Mar '18

08 Mar '18

Hello, this thread last year (started by me... ;-) was very useful in different aspects involved http://lists.ovirt.org/pipermail/users/2017-March/080322.html We did cover memory save or not and fsfreeze automatically done by guest agent if installed inside the VM. What about pre-snapshot scripts/operations to run inside guest, to have application consistency? Eg if I have a database inside the VM and I have scripted my backup job involving live-snapshot (eg with the backup.py utility of the thread) Can I leverage this kind of functionality with the oVirt guest agent? Or is it mandatory to consider a remote connection to the VM (via ssh or what for windows?) and execute the script/command/bat file? What are you curently doing in this respect? Thanks, Gianluca

Tunable parameters in ovirt engine
by Hari Prasanth Loganathan 08 Mar '18

08 Mar '18

Hi Team, *Description of problem:* I am trying to achieve 1000 concurrent request to oVirt. What are the tunable parameters to achieve this? I tried to perform the benchmarking for ovirt engine using Apache benchmark using the same SSO token. ab -n 1000 -c 500 -k -H "accept: application/json" -H "Authorization: Bearer SSOTOKEN" https://172.30.56.70/ovirt-engine/ <https://172.30.56.70/ovirt-engine/api/vms/5440271b-afb3-48bb-9ff1-076fc07eb…> When the number of concurrent request is 500, we are getting more than 100 failures with the following error, SSL read failed (1) - closing connection 139620982339352:error: NOTE: It is scaling for concurrent request below 500. I used the profiler to get the memory and CPU and it seems very less, PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 30413 ovirt 20 0 4226664 882396 6776 S 126.0 23.0 27:48.53 java Configuration of the machine in which Ovirt is deployed : RAM - 4GB, Hard disk - 100GB, core processor - 2, OS - Cent7.x.

Hi, is there any way to power off VM from VM portal (4.2.1.7)? I can't find "power off" button, just "shutdown".

Fibre Channel Protocol (FCP)
by maoz zadok 08 Mar '18

08 Mar '18

Hello All, I connected existing data center with NFS storage domain to a new Fiber-Channel storage domain according to the following guide, and I have three questions. https://www.ovirt.org/documentation/install-guide/chap-Configuring_Storage/ 1. why does the storage domain asks me to "Use Host"? - does it mean that if this host is down there is no access to the FC storage or the next available host elected to manage the FC storage? - does it mean that all the traffic to my storage is routed via the selected host? - what is the best practice, do I need to split the workload to other hosts as well by letting each host manage one small LUN instead of letting one host manage all LUNs or one big LUN? 2. is it possible to set the newly created fiber-channel storage(data domain) as master? 3. can I easily migrate all VM disks to the FC storage instead of the NFS? Thank you!

Unable to start VM after upgrade vom 4.1.9 to 4.2.1 - NPE

Hello, we have upgrade one of our oVirt engines to 4.2.1 (from 4.1.9) and afterwards all nodes too. The cluster compatibility level has been set to 4.2.

I haven't found any matching bug tickets in release notes for upcoming 4.2.1. Can anyone help here? Kind regards Jan Siml

New oVirt blog - Your Container Volumes Served By oVirt
by Yaniv Kaul 07 Mar '18

07 Mar '18

When running a virtualization workload on oVirt, a VM disk is 'natively' a disk somewhere on your network-storage. Entering containers world, on Kubernetes(k8s) or OpenShift, there are many options specifically because the workload can be totally stateless, i.e they are stored on a host supplied disk and can be removed when the container is terminated. The more interesting case is *stateful workloads* i.e apps that persist data (think DBs, web servers/services, etc). k8s/OpenShift designed an API to dynamically provision the container storage (volume in k8s terminology). In this post I want to cover how oVirt can provide volumes for containers running on k8s/OpenShift cluster. Read more @ https://ovirt.org/blog/2018/02/your-container-volumes-served-by-ovirt/
