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?

Hosted Engine VM and Storage not showing up
by ferrao＠versatushpc.com.br 07 Jan '19

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.

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.

Which option is best for storage?
by geoff＠pdclouds.com.au 04 Jan '19

04 Jan '19

Hi, Which is the preferred option for connecting oVirt VM farm to SAN/NAS? NFS (10G), iSCSI (10G) or FC (8G)? We are confused, some people say iSCSI is preferred and others say NFS performs the better than iSCSI, but FC is most expensive but performs the best overall.... Would value expert opinion. Cheers Geoff

Unable to increase memory or CPU on hosted Engine version 4.2.5.2
by Florian Schmid 04 Jan '19

04 Jan '19

Hi, I'm using version 4.2.5.2 and every article I found, I read that with oVirt 4.2, it should be possible to update CPU and memory for hosted Engine in UI. Now, when I'm trying to do this, even being on global maintenance, I always get the same error: Error while executing action: HostedEngine: There was an attempt to change Hosted Engine VM values that are locked. My problem is, that I need to increase the memory, because we had now several times in the last 2 or 3 months an out of memory kill of the java process. What is the best way to increase memory here? Should I do it over the config file? But how is then the OVF updated? BR Florian

Replacing Export Domain by Data Domain
by tehnic＠take3.ro 03 Jan '19

03 Jan '19

Hello all, because using an export domain is deprecated i deleted my export domain and use now a data domain instead. I used the export domain for complete image backups of my production virtual machines. By using now a data domain its even more comfortable because i can clone a snapshot directly on my backup data domain. But there is a (small?) inconvenience: I cannot "unregister" the cloned snapshot and i dont want to see them all the time in the "Virtual Machines" list. For the moment i use a bookmark in the "Vms:" filter. After detaching the domain the VMs are away, reattaching brings them back for possible "Import VM". Is there a possibility to set the cloned VM directly to this "unregistered" state without detaching and reattaching the complete domain? Best regards, Robert
