upgrading 4.0.1 to latest 4.2
by Charles Kozler 15 Aug '18

15 Aug '18

Hello - I am kicking around different ideas of how I could achieve this I have been bitten, hard, with in place upgrades before so I am not really wanting to do this unless its a complete last resort...and even then I'm iffy Really, the only configuration I have is 1 VDSM hook and about 20 networks. The physical hardware is not going anywhere. Out of my three nodes, I can push all VM's to the other 2 nodes and do a fresh build on 1 node I am hoping there may be a way for me to do a fresh install of 4.2, export engine config from 4.0.1, and then import it in some way - is this possible? Quick google doesnt yield much and searches for 'export' usually result in storage related results

[ovirt-engine-api-model] Any solutions to add custom key/value pairs into entities?
by Joey Ma 14 Aug '18

14 Aug '18

Hi all, In my case, I need to add customized KVs into API model entities, such as VM, Disk, Template and etc. I looked through the API model documents and got some existing Tag/Property/CustomProperty structs, all of which have limitations and can not work it out. Are there any solutions? Thanks, Joey

Is there a way to specify which volume is used for VM imports?
by Jayme 14 Aug '18

14 Aug '18

I have multiple data volumes and when I import a VM from an NFS attached export domain the disk always gets created on on specific volume. I understand I can move the disk from one volume to another after the fact but is there a way I can specify which volume to use for the initial import?

Network requirements for ovirtmgmt
by Marcel Hanke 14 Aug '18

14 Aug '18

Hi, we currently have a big layer 2 network in our datacenters, so every node in a cluster can reach the other nodes in the datacenter on network layer 2. In the future we'd like to route directly on the switches and connect the nodes in one cluster, as well es other clusters in one datacenter via network layer 3. The question now is, do we need multicast and/or broadcast for any operation, or is the connectivity with layer 3 fine? Thanks Marcel

Connection issues when using gluster + infiniband + RDMA
by housemouse＠squeakz.net 13 Aug '18

13 Aug '18

I am trying to setup gluster using Infiniband and mounting it in RDMA mode. I have created a network hook so that it configures the interfaces as MTU=65520 and CONNECTED_MODE=yes. I have a second server doing NFS with RDMA over Infiniband with some VMs on it. When I try and transfer files to the gluster storage it is taking a while and I am seeing the message “VDSM {hostname} command GetGlusterVolumeHealInfoVDS failed: Message timeout which can be caused by communication issues” This is usually followed by “Host {hostname} is not responding. It will stay in Connecting state for a grace period of 60 seconds and after that an attempt to fence the host will be issued.” I just installed the Infiniband hardware. The switch is a Qlogic 12200-18 with QLE7340 single port Infiniband cards in each of the 3 servers. The error message varies on which of the 3 nodes it comes from. Each of the 3 servers is running the opensm service.

Passing through Quadro cards to guest
by Wesley Stewart 13 Aug '18

13 Aug '18

Has anyone experimented with this? I have had really good success with AMD cards, but consumer end graphics cards fail to load due to NVIDIA blocking them. I happened to have an NVIDIA Quadro P2000 lying around and I thought I would give it a shot. I really like these cards as they only require the 75W provided PCI power. I can pass the Quadro through just fine, however after a couple minutes of playing a video, the audio gets really "buzzy" and the video drops to about 3-5 FPS. This is while doing pretty minimal stuff. Currently testing with 720/1080 youtube videos. Card is pulling about 6-10W total. And otherwise working fine on my Windows 10 guest. I have also tried enabling/disabling MSI interrupts which the card supports without making a difference. I am running a single host setup: X10SDV-6c+ (Xeon D - 1528) running oVirt 4.2.3

Isolated POC
by Martin Schutte 13 Aug '18

13 Aug '18

Good day to all, I am in the process of setting up an oVirt proof of concept for a client. There are some strict requirements for this POC. Firstly the entire POC must be isolated from the network, which means no online repos. Secondly there is a time constraint for the completion of the deployment. All to be done on bare-metal systems. I have installed oVirt numerous times on other systems, but then I was always able to have online repos. So in short I am asking for some pointers on which repos needs to be synced offline for this to work properly. I can always go and play around to figure out which ones are needed, but I do not have the luxury of time. Any advice or tips will be appreciated. Regards, Martin.

oVirt node 4.2.x - custom multipath.conf and external storage availability
by Roberto Nunin 13 Aug '18

13 Aug '18

HI all How can I provide to my oVirt hosts a custom multipath.conf, considering that we are using shared/mirrored FC storage from HPE 3PAR with high availability of provided LUNs, using peer-persistance feature ? To configure correctly this require a custom multipath.conf is required. How I can avoid it will be overwritten during upgrades ? Second topic: Is ALUA feature supported also in oVirt nodes, like for standard RHEL 6/7 and/or CentOS 6/7 ? I was digging for a while into user's digest, but not able to find focused informations. This is the feature needed by peer-persistance, allowing two different volumes to be masked toward a given host with the same WWN and LUN number. Thanks in advance -- Roberto

ovirt engine service needs restart after network connectivity is lost and reestablished
by g.vasilopoulos＠uoc.gr 13 Aug '18

13 Aug '18

today our network administration did some upgrades on the networking equipment, so the engine vlan went down for a while. Afterwards when it came back up 3 hosts was found as non responding, I couldn't see anything suspicious on the hosts, the problem "fixed" itself when I restarted the ovirt-engine service on the engine vm. Another "strange" side effect is that gluster was in need of healing constantly afterwards it did heal and desynch again almost immediately, whitch was "fixed" by shutting down and starting the vm's who were up at the time of the network outage.. I've seen this behaviour once more regarding the engine service, is this normal behaviour (e.g. to make the admin check if everything is ok) or is there something wrong ?

cannot activate host
by Jiří Sléžka 12 Aug '18

12 Aug '18

Hi, I have one interesting issue. I was asked by colleague to repair his cluster which is part of our oVirt installation. He tried to upgrade his host to gain 4.2 compatibility level but it fails in some cases. Never mind, I checked it, repaired, installed upgrades and activate his hosts with one exception. One of hosts was stucked in finishing two tasks. One was changing network configuration, the second was activating of this host. I have to manually clear this tasks in database by SELECT * FROM job ORDER BY start_time DESC; SELECT DeleteJob('...job_id...'); SELECT DeleteJob('...job_id...'); Now this tasks are gone but still cannot activate this host. Error while executing action: blade01: Cannot activate Host. Related operation is currently in progress. Please try again later. Host is updatet (latest 4.2 repo), rebooted, looks fine... In tasks in UI are no tasks found (the same in db)... What can I do now? Cheers, Jiri

Re: Live Migration via NFS

Hi Nir Thanks for clarifying We can still use NFS as export domain which can be used to move VM once they're shutdown? Can GPFS be used to provide shared block storage domain?

Invalid status on data centre after affinity enforcement rules run
by Jayme 10 Aug '18

10 Aug '18

I have a newly built three node HCI glusterFS cluster (deployed with cockpit) running ovirt 4.2.5 I'm noticing that a few times a day I'm seeing the following event log: Invalid status on Data Center Default. Setting status to Non Responsive. In every single case it happens about 10 seconds after the previous event log: Affinity Rules Enforcement Manager started. Is it normal to see this temporary non responsive state of the default data center? I've also noticed something a bit odd with my hostedEngine. It seems to be restarting on its own and correlates to around the time the above warnings are in the event log. My hosted engine says it has an uptime of 10 minutes right now but I haven't touched it or rebooted it in several days. The events for hostedEngine specifically don't show any logs or problems for several weeks. Question is, why is the default data center intermittently going non-responsive and why is my hostedEngine seemingly restarting itself?

Drive letter / scsi id not consistent
by Nathan March 09 Aug '18

09 Aug '18

Hi, Managing disks in the ovirt gui seems completely error prone since the GUI ordering does not seem to be used in any practical way. The scsi ID's are not exposed via the GUI either, so if you have 2 drives of the same size on NFS there's no way to identify which is which without resorting to dumping the xml. I see in the xml that the target dev is correct and matches up with the GUI's drive order, but the scsi unit seems to be generated based on the order of last activated: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/b622cde9-ffc4-487b-8038-f7cb7fbc00a1/7240b4b2-5ab1-40ab-99bb-09c69fd835f6'/> <backingStore/> <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/86765f60-4240-44f4-b437-f22b2cc3df1a/482a363e-461a-4f37-876c-43ceb529a93a'/> <backingStore/> <target dev='sdb' bus='scsi'/> <serial>86765f60-4240-44f4-b437-f22b2cc3df1a</serial> <alias name='ua-86765f60-4240-44f4-b437-f22b2cc3df1a'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/0b020d24-3dea-4be7-931a-9c25ccfeec48/7e3957ff-a3bf-4080-a7b6-ddad7f63a299'/> <backingStore/> <target dev='sdc' bus='scsi'/> <serial>0b020d24-3dea-4be7-931a-9c25ccfeec48</serial> <alias name='scsi0-0-0-3'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> </disk> After deactivating the other 2 disks and rebooting the machine, sda has now become unit 3: <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> and then I shutdown, activated the extra 2 drives, booted it back up but now I'm still on unit 3: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/b622cde9-ffc4-487b-8038-f7cb7fbc00a1/7240b4b2-5ab1-40ab-99bb-09c69fd835f6'/> <backingStore/> <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/86765f60-4240-44f4-b437-f22b2cc3df1a/482a363e-461a-4f37-876c-43ceb529a93a'/> <backingStore/> <target dev='sdb' bus='scsi'/> <serial>86765f60-4240-44f4-b437-f22b2cc3df1a</serial> <alias name='ua-86765f60-4240-44f4-b437-f22b2cc3df1a'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/0b020d24-3dea-4be7-931a-9c25ccfeec48/7e3957ff-a3bf-4080-a7b6-ddad7f63a299'/> <backingStore/> <target dev='sdc' bus='scsi'/> <serial>0b020d24-3dea-4be7-931a-9c25ccfeec48</serial> <alias name='ua-0b020d24-3dea-4be7-931a-9c25ccfeec48'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> I managed to get things into the correct state by shutting down the VM, deactivating all the disks, then activating them in the order I want them to show up. This sets the correct order of unit 0 for sda, unit 1 for sdb, unit 2 for sdc. Is there some way to make ovirt treat this in a sane way and always expose the scsi devices in the same order as the GUI (and the "target dev" field)? Cheers! Nathan

Live Migration via NFS
by Douglas Duckworth 09 Aug '18

09 Aug '18

Hi I haven't used oVirt in several years so wanted to ask how live migration may have changed. Can NFS facilitate live migration in cluster of two hosts each which have NFS mounted? The hosts would have local attached storage which would be the original location of VMs.

Hello, I have 24 HP DL360 G7 all with 64G RAM and 1TB SAS disks. What I want to archive is to use all the nodes with ovirt (one will be for the controller + iso domain) and use GluterFS in the same nodes for the storage domain. Idk if anyone tried it before, but I want it to replace my actual "standalone" production hypervisors schema. Thanks in advance

Hello, I have a problem when i tried to hotplug a disk to a VM. Here is the situation. We use a VM (let's call this backupVM) which is responsible of doing our VM backup by : - Making a snapshot of the VM we want to backup - Attach the snapshot disk - Make the copy using DD - Unplug the snapshot disk and then delete snapshot. For some reason that i don't know, for certain VM, the backupVM cannot hot plug the snapshot disk.

VirtIO in new upgraded 4.2.5 for FreeBSD is very poor (could not use)
by Paul.LKW 08 Aug '18

08 Aug '18

Dear All: I just upgraded my oVIrt-4.2.4 to 4.2.5 and nightmare begin, FreeBSD VMs hangs once the VM's VirtIO harddisk is some loading (eg. extracting a big tar ball, portsnap extract, etc.), I tried to create a VMs using back the IDE do not has any problem but got slow IO performance once using VirtIO it will hang as it like. I also tried to create another VMs with VirtIO-SCSI it seems the hang problem no occur but I got the oVirt-Host loading over 40 when VM harddisk have some little job, so conclusion is if you guys will using FreeBSD as guest please do not upgrade at the moment. In fact I feel every time the new version always have problem and causing user to nightmare. BR, Paul.LKW

Space in entity names (VM and Network) in oVirt
by Hari Prasanth Loganathan 08 Aug '18

08 Aug '18

Hi Team, I have VM's and Network's in oVirt with space in the name. How can I perform an exact search for the following name *Name1*: Aug X X *Name2*: Aug X X X 1) I try to search with space in the name, It is not working. https://172.30.60.42/ovirt-engine/api/networks?search=name%3DAug X X It is not returning any result. 2) I try to search with encoded value for space in the name, It is not working. (encoded value for space is %20) https://172.30.60.42/ovirt-engine/api/networks?search=name%3DAug%20X%20X 3) I try to search like below with '*' for space and end up getting both the values in response, https://172.30.60.42/ovirt-engine/api/networks?search=name%3DAug*X so what is the correct way to search the name with space ?

Re: Update to 4.2.5, Cant start VMs

Indeed the Storage domains are via NFS served by Windows Server 2016. the workaround says "use NFSV3", I'm afraid this will break my existing installation. For now, all my VMs are running on one host that is still on 4.2.0.

Update to 4.2.5, Cant start VMs
by Vincent Royer 07 Aug '18

07 Aug '18

I updated the engine, and one of my nodes to 4.2.5. I'm attempting to re-start the VMs that were pinned to it, and migrate another VM to it so that I can update my other node. When I try to start the VMs that were pinned to the host, I get: VM Tuning3 is down with error. Exit message: XML error: Multiple 'scsi' > controllers with index '0'. To fix this I tried to detach the disk and re-attach it, no luck. When I try to migrate a running VM to this host, I get: Host Letty has network interface which exceeded the defined threshold [95%] > (bond0: transmit rate[0%], receive rate [97%]) The host I'm migrating FROM gets a similar error, and the VM does not migrate. I tried the different migration policies without any luck. I did successfully migrate the Hosted Engine to the new host, no errors. Thanks for any advice! Vincent

better understand ovirt-engine functions
by stuartk＠alleninstitute.org 07 Aug '18

07 Aug '18

I've been reading through documentation https://www.ovirt.org/documentation/architecture/architecture/ https://www.ovirt.org/documentation/self-hosted/Self-Hosted_Engine_Guide/ But am struggling still to understand the role ovirt-engine plays. Would anyone have recommends for additional reads? The problem I'm tackling currently looks like this: - We have (2) oVirt Data Centers, each populated by a single Cluster. The Data Centers are physically & network-wise 'distant' from one another - hosted-engine runs on (3) of the (4) Hosts in Data Center A / Cluster A. hosted-engine does not run on Data Center B / Cluster B - When we disrupt network connectivity around Cluster A (yes, that's Cluster *A*), Hosts in Cluster B crash (requiring a power cycle) and Guests in Cluster B get stopped and paused I'm struggling to understand why mussing with Cluster A affects Cluster B. From pcaps, I can see plenty of TLS traffic from Cluster A's Hosts -- presumably from ovirt-engine running on Cluster A -- exchanged with Cluster B. So, during my last maintenance window, I put hosted-engine into maintenance mode ... but Hosts/VMs in Cluster B were still affected. Where do I go to better understand what ovirt-engine does when it is 'managing' Hosts & VMs? --sk

Datacenter of several Hosts with Local Storage ? (share Logical Network)
by jeanbaptiste＠nfrance.com 07 Aug '18

07 Aug '18

Hello, My question is pretty simple :) Is there a way to configure Local(s) Storage Datacenter with more than 1 host ? The goal is is to share some Datacenter simple parameters between several hosts (with Local storage) like Logical Networks ? If it is not possible what is the best way / workaound to do this ? To compare, on Xenserver, it is possible to configure a "Pool" of some hosts which have Local Storage, but which share same Logical network configuration.. (I do not say XS is better^^, far from it !) Thanks for all :) Jean-Baptiste

MoM - Not working ? How to use it ?
by jeanbaptiste＠nfrance.com 07 Aug '18

Hello, I'm trying to test Memory balloon useful functionality, but l'm unable to make it work successfuly. Firstly, I enable the MOM on my Cluster: Memory Balloon Enable Memory Balloon Optimization Secondly, I configure a VM virtual machine like this: On system tab: Memory Size : 28672 MB Maximum memory : 28672 MB On Ressource allocation tab: Memory Allocation: Physical Memory Guaranteed : 2048 MB Memory Balloon Device: Enabled Thirdly, I test 1- I boot the VM. After boot VM consume 200MB 2- I lauch perl program which consume 26GB. 3- During this, Host RAM usage is near 90% 4- I stop the perl program, and on guest side, RAM usage drop down to 200Mo 5- On host side, RAM usage keep to 24 - 26GB. I wait some time to show if the qemu-vm process drop is host-ram-usage. Ram usage keep to 24GB. 6- I try to launch another VM like the first one (but with 8GB RAM and 2GB Guaranteed) , on the host (to "force" Mom ?) but I'm unable to lauch it, Host free mem is insufficient I change MoM log to debug to show something: 2018-07-31 11:49:31,887 - mom.RPCServer - INFO - ping() 2018-07-31 11:49:31,888 - mom.RPCServer - INFO - getStatistics() 2018-07-31 11:49:31,888 - mom.Monitor - DEBUG - Field 'mem_free' not known.

Tuning and testing GlusterFS performance
by Jayme 07 Aug '18

07 Aug '18

So I've finally completed my first HCI build using the below configuration: 3x Dell PowerEdge R720 2x 2.9 GHz 8 Core E5-2690 256GB RAM 2x250gb SSD Raid 1 (boot/os) 2x2TB SSD jbod passthrough (used for gluster bricks) 1Gbe Nic for management 10Gbe nic for Gluster Using Replica 3 with no arbiter. Installed the latest version of oVirt available at the time 4.2.5. Created recommended volumes (with an additional data volume on second SSD). Not using VDO First thing I did was setup glusterFS network on 10Gbe and set it to be used for glusterFS and migration traffic. I've setup a single test VM using Centos7 minimal on the default "x-large instance" profile. Within this VM if I do very basic write test using something like: dd bs=1M count=256 if=/dev/zero of=test conv=fdatasync I'm seeing quite slow speeds, only 8mb/sec. If I do the same from one of the hosts gluster mounts i.e. host1: /rhev/data-center/mnt/glusterSD/HOST:data I get about 30mb/sec (which still seems fairly low?) Am I testing incorrectly here? Is there anything I should be tuning on the Gluster volumes to increase performance with SSDs? Where can I find out where the bottle neck is here, or is this expected performance of Gluster?

Hello, when i tried to attach a snapshot disk into my backupvm. oVirt doesn't want to attach it. In the engine.log I can see this. 2018-08-04 19:20:04,472-10 ERROR [org.ovirt.engine.core.bll.storage.disk.AttachDiskToVmCommand] (default task-33) [646ad7a1-4501-4648-a937-bbee0abaec46] Command 'org.ovirt.engine.core.bll.storage.disk.AttachDiskToVmCommand' failed: CallableStatementCallback; SQL [{call insertdiskvmelement(?, ?, ?, ?, ?, ?)}]; ERROR: duplicate key value violates unique constraint "pk_disk_vm_element" Detail: Key (vm_id, disk_id)=(78ef239f-3cb3-4eef-921f-f989724009ef, c7cef731-e31d-4597-80f1-1f2393cd66ea) already exists. Where: SQL statement "INSERT INTO disk_vm_element ( disk_id, vm_id, is_boot, pass_discard, disk_interface, is_using_scsi_reservation) VALUES ( v_disk_id, v_vm_id, v_is_boot, v_pass_discard, v_disk_interface, v_is_using_scsi_reservation)" PL/pgSQL function insertdiskvmelement(uuid,uuid,boolean,boolean,character varying,boolean) line 3 at SQL statement; nested exception is org.postgresql.util.PSQLException: ERROR: duplicate key value violates unique constraint "pk_disk_vm_element" Detail: Key (vm_id, disk_id)=(78ef239f-3cb3-4eef-921f-f989724009ef, c7cef731-e31d-4597-80f1-1f2393cd66ea) already exists. When i SQL the database, the entries is present (and many other). But in the webinterface, I can't see them on the backupVM. It's just like ovirt didn't delete old entries engine=# select * from disk_vm_element where vm_id = '78ef239f-3cb3-4eef-921f-f989724009ef' and disk_id = 'c7cef731-e31d-4597-80f1-1f2393cd66ea' ; disk_id | vm_id | is_boot | disk_interface | is_using_scsi_reservation | pass_discard --------------------------------------+--------------------------------------+---------+----------------+---------------------------+-------------- c7cef731-e31d-4597-80f1-1f2393cd66ea | 78ef239f-3cb3-4eef-921f-f989724009ef | f | VirtIO | f | f (1 row) Do you guys have any idea on how to correct this ? Is there any function to update / refresh this table ? I dont want to delete entries by sql as i don't know the consequences, is it safe to delete entries ? Thank you for your help
