Hi, we are planning to release a 4.3.0 RC2 tomorrow morning, January 16th 2019. We have a scheduled final release for oVirt 4.3.0 on January 29th: this is the time when testing is most effective to ensure the release will be as much stable as possible. Please join us testing the RC2 release this week and reporting issues to https://bugzilla.redhat.com/enter_bug.cgi?classification=oVirt Please remember this is still pre-release material, we recommend not installing it on production environments yet.

Ansible and SHE deployment
by Vrgotic, Marko 15 Jan '19

15 Jan '19

Dear oVirt team, I would like to ask you help in get some general guidelines, do’s & don’ts in deploying complete oVirt environment using Ansible. The first Production deployment I made was done manual: 12 Hypervsiors – all exact same HW Brand and Specs 3/12 used for HA Env for SHE oVirt version 4.2.1 (now we are at 4.2.7) 4Gluster nodes, managed externally of oVirt This is environment I would like to convert into deployable by Ansible Atm, I am working on second Production env, for Eng/Dev department, and I want to go all way Ansible. I am aware of your playbooks, and location on github, but what I want to ask is an advice on how to approach using them: The second Env will have: 7Hypervisors different specs / all provisioned using Foreman oVirt version, latest 4.2.x at that point. 3/7 providing HA for SHE engine Storage used is to be NetApp. Please let me know how to proceed with modifying Ansible playbooks and what should be the recommended executing order, and what to look for? Also, If you need additional info, I will be happy to provide. Kind regards, Marko Vrgotic

Import existing storage domain into new server
by michael＠wanderingmad.com 15 Jan '19

15 Jan '19

I had original ovirt-engine that had stuck tasks and just had storage issues. I decided to load a new engine appliance and import existing servers and VMs into new engine. This actually worked perfect until I went to import the storage domain into new engine, which has failed. I was unable to move the domain to maintenance mode or anything from the old engine. Any way to force import? Error messages / logs: Failed to attach Storage Domains to Data Center Default.

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

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

File level restore of a VM backup located in export domain in Overt
by kevin.doyle＠manchester.ac.uk 10 Jan '19

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. I can also carry out a full restore from this by importing from the export domain and selecting the backup. The question I have is how to do a single file recovery from the backup image. I would like to restore /etc/hosts just as an example. What command would I use ? I am not sure of the layout of the export domain directory ── dom_md │ ├── ids │ ├── inbox │ ├── leases │ ├── metadata │ └── outbox ├── images │ └── 622eb98e-f10b-4e96-bec5-8f0a7e7745fe │ ├── b47ce8e1-f552-47f8-af56-33a3b8ce7aed │ └── b47ce8e1-f552-47f8-af56-33a3b8ce7aed.meta └── master ├── tasks └── vms └── c6e6c49c-c9bc-4683-8b19-d18250b5697b └── c6e6c49c-c9bc-4683-8b19-d18250b5697b.ovf The largest file is found is in images folder so I assume this is the backup image ? ./images/622eb98e-f10b-4e96-bec5-8f0a7e7745fe: total 2.7G drwxr-xr-x. 2 vdsm kvm 99 Jan 10 11:48 . drwxr-xr-x. 3 vdsm kvm 50 Jan 10 11:48 .. -rw-rw----. 1 vdsm kvm 50G Jan 10 11:51 b47ce8e1-f552-47f8-af56-33a3b8ce7aed -rw-r--r--. 1 vdsm kvm 269 Jan 10 11:48 b47ce8e1-f552-47f8-af56-33a3b8ce7aed.meta # file b47ce8e1-f552-47f8-af56-33a3b8ce7aed b47ce8e1-f552-47f8-af56-33a3b8ce7aed: x86 boot sector; partition 1: ID=0x83, active, starthead 32, startsector 2048, 2097152 sectors; partition 2: ID=0x8e, starthead 170, startsector 2099200, 102758400 sectors, code offset 0x63 Any help would be appreciated, I am new to Ovirt regards Kevin

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.
