oVirt Node install - kickstart postintall
by jeanbaptiste＠nfrance.com 14 Jan '19

14 Jan '19

Hello everybody, Since days, I'm trying to install oVirt (via Foreman) in network mode (TFTP net install). All is great, but I want to make some actions in postinstall (%post). Some actions are relatated to /etc/sysconfig/network-interfaces and another action is related to root authorized_keys. When I try to add pub-key to a created authorized_keys for root, I work (verified into anaconda. But after installation and anaconda reboot, I've noticed all my %post actions in /(root) are discared. After reboot, there is nothing in /root/.ssh for example. Whereas, in /etc, all my modications are preserved. I thought to a Selinux relative issue, but It is not relative to Selinux I miss something. Please can you help to understand how oVirt install / partition work ? thanks for all

Ovirt 4.3 / New Install / NFS (broken)
by Devin Acosta 14 Jan '19

14 Jan '19

I installed the latest 4.3 release candidate and tried to add an NFS mount to the Data Center, and it errors in the GUI with “Error while executing action New NFS Storage Domain: Invalid parameter”, then in the vdsm.log I see it is passing “block_size=None”. Does this regardless if NFS v3 or v4.

Trunk VLAN Ovirt 4.2
by Sebastian Antunez N. 14 Jan '19

14 Jan '19

Hello Guys Have a lab with 6 nodes Ovirt 4.2. All nodes have 4 nic 1GB and two nic are for Management and and I will assign two nic in bonding for VM traffic My problem is the following. The switch Cisco have 2 VLAN (56 and 57) and I need to be able to create a new network with the two vlan but I am not clear how to make it so that the vlan go through this created network. I have read that I must create a network with vlan 56 for example and assign it an IP, and then create the network with vlan 57 and assign it an IP and later assign it to bonding. Is what I indicate or should another process be correct? Thanks for the help. Sebastian

Ovirt VDI Solution network issue
by mdcarr＠meditech.com 11 Jan '19

11 Jan '19

Hello, first time poster looking for help on setting up the network for a VDI deployment. A little background, I have Ovirt engine running on a Vmware virtual machine and have added a physical host to serve up virtual machines running windows 7 to our developers. The host has a static IP address and when I create a virtual machine I can see the default network is attached and up but does not receive an IP address. It does have a MAC so I'm wondering if I need to have our network team assign an IP for that MAC? I will be creating around 20 vm's that would get wiped after use so assigning static ip's might cause issues. Am I missing something or is there a better way to setup the LAN for this host? Thanks for any help!

Hypervisor host CPU utilization metrics
by Sigbjorn Lie-Soland 11 Jan '19

11 Jan '19

Hi, Linux see twice the amount of CPUs for a host with SMT/hyperthreading enabled. Inspecting the individual cores presented to the operating system using mpstat shows that the guests are running primarily on the “physical cores”, which is expected as the system is SMT aware. The “hyperthreaded cores” are showing guest activity when the host cpu is heavily loaded. Using the traditional tools such as top and vmstat does not take hyperthreading into consideration when calculating the total cpu% usage, again, as expected. How is the hypervisor host CPU utilization metrics in Ovirt calculated when a hypervisor host has SMT/hyperthreading enabled? Does Ovirt calculate in the same manner as the traditional vmstat/top/etc Linux tools, or does it only count CPU usage on the “physical cores” on the hypervisor? Does it read CPU metrics from the Intel PCM (https://github.com/opcm/pcm <https://github.com/opcm/pcm>) ? Does the “Count Threads as Cores” setting affect how the host hypervisor CPU utilization metrics are calculated? The reason for asking is when using tools for capacity and utilization reporting to attempt to establish cluster growth and to anticipate when and how much hypervisor capacity to add, we need the input utilization data to be a correct representation of what is happening at the hypervisor host. Thanks. Regards, Siggi

quota_name field length missmatch in db schema
by Pavel Šipoš 11 Jan '19

11 Jan '19

Hi! We have a problem with Quotas whose name has a length grater than 60 characters. Such quotas can be created (or renamed) through oVirt-shell but cannot be managed through the oVirt Engine interface. E.g. VMs in that quota can't be started, created, quota comment can't be added... It turns out that the problem is with the engine database definition of "audit_log" table, that declares "quota_name" column as "character varying(60)". However "quota.quota_name" is defined as "character varying(65)". I think this is a bug and should be fixed in the future. Error example: PL/pgSQL function insertauditlog(integer,timestamp with time zone,integer,character varying,integer,text,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,character varying,uuid,uuid,character varying,text,boolean,uuid,text) line 9 at SQL statement; nested exception is org.postgresql.util.PSQLException: ERROR: value too long for type character varying(60) Regards, Pavel

Hi I would like to create backups of VM's using cron. I have installed and ran https://github.com/wefixit-AT/oVirtBackup This works well and saves an image to the export domain I created.

VMs Hung On Booting From Hard Disk
by Douglas Duckworth 09 Jan '19

09 Jan '19

Hi I have deployed 10 VMs in our oVirt cluster using Ansible. Thanks everyone for helping get it working. However, I randomly run into issues where the OS won't load after completing kickstart installation. As you can see the disks are attached while we are booting to it however I keep getting a hang at "booting from hard disk." The kickstart, kernel, and everything else for this VM, matches others. I am unsure why this problem occurs. I have attached repeating vdsm errors from the host which has the VM.

oVirt upgrade 4.1 to 4.2
by p.staniforth＠leedsbeckett.ac.uk 09 Jan '19

09 Jan '19

Hello when we did a live upgrade of our VDC from 4.1 to 4.2 we had a large number of VMs running that had a Custom Compatibility Version set to 4.1 to allow them to keep running while the cluster and VDC were upgraded. Unfortunately there was a large number of snapshots taken be the users before they were restarted their VMs so they have the Custom_Compatibility_Version set to 4.1 and so can't run in the 4.2 VDC, is there a way to search for them in the API or SDK because I can only find them in the events log when they fail to start. Thanks, Paul S.

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

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

oVirt Node 4.2.5.1 vm stuck on "Powering Down"
by maoz zadok 03 Jan '19

03 Jan '19

Hello, vm stuck (on two hosts) I have MySQL VM guest that was stuck in a way that "kill -9" to the MySQL server pid did nothing. from the shell I execute "init 0", this did not shut down the VM. from the ovirt-engine I'm trying to power off the machine, and it is not doing anything. the event shows: > VDSM kvm5 command DestroyVDS failed: Virtual machine destroy error > and: > Failed to power off VM mysql-production (Host: kvm5, User: > admin@internal-authz). > Note, when I list the VM s on the hosts view, I see that that same VM is on two hosts (kvm7 and kvm5). It looks like the VM is stuck on two hosts, in the status "Powering Down" any ideas? Thank you

GlusterFS Storage - Size limited at 2 GB
by v.levet＠isiline.net 03 Jan '19

03 Jan '19

Hello everyone, I've installed oVirt on 8 nodes of a MacroServer (SuperMicro Microcloud): 7 Nodes with oVirt Node installed and 1 Node with Centos 7 and oVirt installed. The last one works like hypervisor and node. I would use all the storage of all nodes like a Gluster storage, so I've created a new DataCenter, with a Cluster with all nodes inside. Then I've created the volume Gluster (by GUI): Replicated Duplicated version and 4 replicas on all 8 nodes. Than "Optimize for oVirt Storage". For last I've created Domain storage based on volume created before. All works fine but the total storage that is available from Domain is 1.9 GB. I've tried already to force it using these commands: gluster volume GlusterVol limit-usage / 3200GB gluster volume quota GlusterVol limit-usage /data 3200GB At first it seems work but finally when I was installing a VM, I get Full Storage. It seems that it could use only the storage of the node where is instantiated the volume. I would see all the storage distributed and I wish I could use the storage from all nodes. Someone could help me?
