novnc in the virtual machine console
by xilazz＠126.com 07 Jan '19

Hello everyone, When I was using novnc in the virtual machine console, I could not see the virtual machine content after opening it. Always prompt: Can't connect to websocket proxy server wss://engine.test.com:6100. Please check that: websocket proxy service is running, firewalls are properly set, websocket proxy certificate is trusted by your browser. Default CA certificate. But my engine websocket agent is running normally, now I do not know the reason, please help me check whether there is the same problem Thank you very much ! Cheers,

Hello, I’ve a new oVirt installation using oVirt 4.2.7.1 Node and after deploying the hosted engine it does not show up on the interface even after adding the first storage. The Datacenter is up but the engine VM and the engine storage does not appear. I have the following message repeated constantly on /var/log/messages: Jan 4 20:17:30 ovirt1 journal: ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config.vm ERROR Unable to identify the OVF_STORE volume, falling back to initial vm.conf. Please ensure you already added your first data domain for regular VMs What’s wrong? Am I doing something different?

hello everyone. I want to take a snapshot for hosted-engine. I am intend to do the job that might do critical damages on hosted-engine such as to seperate the database from the engine. before I do these job, it will be nice that I take a snapshot for the engine and then recover it when occuring severe problems. However, I tried to take a snapshot for hosted-engine in RHV-M portal and failed to take the snapshot. Is there any ways taking a snapshot for hosted-engine?

oVirt QueryType
by Anastasiya Ruzhanskaya 06 Jan '19

06 Jan '19

Hello everyone! I am investigation POST requests oVirt makes during the startup while entering to the webadmin. The first is xsrf token, second is QueryType with type 231. I am a little bit confused: if I counted correctly , 231 is Search type. What it searched exactly? It is not specified in message. The answer to this query is aaa.ProfileEntry. Am I missing something? Then in the third message I see such queries as GetAllVmIcons, GetBookmark which seems rather strange ( because no vms are shown on the dashboard). Or I am counting enum values incorrectly?

IoT Big Data design on AWS
by Soujanya Bargavi 05 Jan '19

05 Jan '19

I'm trying to design a big IoT solution of millions of devices starting from zero. That's why I need a highly scalable platform like AWS. My devices are going to report data using AWS IoT, and that's the only thing I've really decided. I need to store a lot of data like a temperature measure every 15 minutes on each device so for that measures I've planned to insert those measures directly to DynamoDB using IoT Rules, but on the other side, I need a relational structure to store companies, temperature sensors, etc. So I thought I could store that in MySQL RDS. After that, I need to configure a proper analysis tool, so I was thinking of Kinesis and load the data from Redshift after ETL using Data Pipeline since AWS https://goo.gl/n2qNUi Glue doesn't support DynamoDB. I'm new with some of the services so I don't know exactly what I'm doing and I don't know if this approach is the best one. What do you think?.

Ovirt Engine UI bug- cannot attache networks to hosts
by Leo David 05 Jan '19

05 Jan '19

Hi Everyone, Using self hosted-engine 4.2.7.5-1.el7 running on ovirt-node 4.2.7, i am trying to attache hosts to a newlly created network for gluster/migration traffic. Oncei click on Networks->gluster-Hosts- Unattached, i get the following error: Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : M9(...) is null Please have your administrator check the UI logs So to make the cluster installation possible, i had to use ovirt 4.2.2 and manually install ovirt-engine-appliance-4.2-20180626.1.el7 on the nodes before deploying self-hosted engine ( version that has other problems, like not being able to get dasboards in cloudforms/manageiq - ovirt-engine-dwh is missing ). Is it possible to: 1. upgrade actual hosted-engine version to the latest that has this module properly installed ? 2. fix the latest ( upgraded ) version so i can attach hosts to networks ? Thank you very much ! Leo -- Best regards, Leo David

oVirt Storage questions
by michael＠wanderingmad.com 04 Jan '19

04 Jan '19

From previous thread about gluster issues, things seem to be running much better than before, and it has raised a few questions that I can't seem to find any answers to: Setup: 3 hyperconverged nodes each node has 1x 1tb SSD and 1x 500gb nVME drive each node is connected via ethernet and also by a 40gb infiniband connection for the gluster replication. Questions: 1. I created a 3tb VDO drive on the SSD and a 1.3tb VDO Drive on the nVME drive with a 1Gb cache on each server and I enabled the RDMA transport.
