[Cannot edit VM. Maximum number of sockets exceeded.]
by Matthias Leopold 09 Jan '19

09 Jan '19

Hi, when a user is managing a "higher number" (couldn't find the exact number yet, roughly >10) of VMs in VM Portal and wants to edit a VM he gets a "[Cannot edit VM. Maximum number of sockets exceeded.]" error message in the browser, which I also see in engine.log. I couldn't find the reason for this. I'm using squid as a SPICE Proxy at cluster level. oVirt version is 4.2.7, can anybody help me? thx matthias

ISCSI Domain & LVM
by tehnic＠take3.ro 09 Jan '19

09 Jan '19

Hello all, i have a question regarding this note in ovirt storage documentation: **Important:** If you are using block storage and you intend to deploy virtual machines on raw devices or direct LUNs and to manage them with the Logical Volume Manager, you must create a filter to hide the guest logical volumes. This will prevent guest logical volumes from being activated when the host is booted, a situation that could lead to stale logical volumes and cause data corruption. What does "you must create a filter to hide the guest logical volumes" exactly mean? I assume i have to set some filter in lvm.conf on all ovirt hosts, but im not sure about what to filter? What i already saw is that after creating the ISCSI domain and cloning/moving/creating virtual machines on it there are new PVs and LVs visible on the ovirt hosts having an object UUID in the name (output from "pvs" and "lvs" commands). Is this expected behavior or do i have to filter exactly this ones by allowing only local disks to be scanned for PVs/LVs? Or do i have to setup filter to allow only local disks + ISCSI disks (in my case /dev/sd?) to be scanned for PVs/LVs? I noticed too that after detaching and removing the ISCSI domain i still have UUID PVs. They all show up with "input/output error" in the output of "pvs" and stay there until i reboot the ovirt hosts. On my ISCSI target system i already set the correct lvm filters so that "targetcli" is happy after reboot. Thank you! Happy new year, Robert

Shutdown VMs when Nobreak is on Battery
by Vinícius Ferrão 08 Jan '19

08 Jan '19

Hello, I would like to know if oVirt support VMs shutdown when a battery threshold on the nobreak device is reached. There are some fencing agents for APC devices, so I’m hoping this is supported. If not, how are you guys doing this kind of thing? A separate device or VM in the datacenter to issue the shutdown commands? Thanks,

oVirt Storage questions
by michael＠wanderingmad.com 08 Jan '19

08 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. a. Did I lose anything by doing the whole process manually? Since I did it like that, things seem to run MUCH better so far, rebooting nodes the gluster resyncs almost instantly and storage seems faster also. b. Is there a way to split out the gluster traffic from the normal ovirt traffic (VM and cluster communication)? originally I had separate names for each node for the gluster network and it WAS split, but if I ever reset a gluster node, the name got changed. What I did now is just put in a hosts file on each node that sends all traffic over the infiniband, but I don't feel like that's optimal. I was unable to add in the separate gluster names in the configuration as they were not part of the existing cluster. c. Why does the hyper-connverged wizard not let you adjust the VDO cache size, the transport type, or use VDO to "over-subscribe" the drive sizes like I did manually? 2. I wanted to add more space in the near future, would it be better to create a RAID0 with the new drives, or just use them as another separate storage location?

Unable to add storage domain
by michael＠wanderingmad.com 08 Jan '19

08 Jan '19

1. Created a lv on a VDO device, mounted on /gluster_bricks/brick 2. Created a new gluster brick on /gluster_bricks/brick/brick 3. Unable to add them new a new storage domain or import it. get a bunch of "finished disconnecting storage..." errors and nothing happens I've lost 30+ VMs due to previous issues with gluster deployment wizard, so I created drives manually to match settings from wizard, totally screwed now.

move 'ovirtmgmt' bridge to a bonded NIC team
by Shawn Southern 08 Jan '19

08 Jan '19

We've recently added additional NICs to our oVirt nodes, and want to move the ovirtmgmt interface to one of the bonded interfaces, away from the single ethernet port currently used. This is to provide redundant connectivity to the nodes. I've not had any luck finding documentation on how to do this. If we change it manually by editing files in /etc/sysconfig/network-scripts, VDSM simply changes everything back. I'm just looking to be pointed in the right direction here. Thanks!

Removing SSL 3 from port 16514
by John Nguyen 08 Jan '19

08 Jan '19

Hello, I was hoping to remove SSL 3 from 16514/tcp. I’m running Ovirt 4.2.0.2-1el7.centos and that port accepts both TSL 1.2 and SSL 3. Would editing libvirtd.conf and restarting libvirt on the hosts be the best way? I worry that it maybe overwritten the next time vdsm gets updated. #vi /etc/libvirt/libvirtd.conf tls_priority="NORMAL:!VERS-SSL3.0" Any help would be appreciated, Thanks John

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

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

Information about un-imported VMs. Delete Request.
by Jacob Green 03 Jan '19

03 Jan '19

I have a Fiber Channel domain, it works, there are some VMs in the VM import tab of the domain that I want to remove, I cannot import them, because they technically already exsist with a duplicate VMID. Is there a way to do this? Alternatively if I cannot delete the data related the the imports, I want to remove the disks attached to these un-imported VM's to free up space on my Fiber Channel, is there a way to reliably identify which LVM id's belong to those un-imported VMs? Thank you. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690
