Bad Gateway buhaa
by Vrgotic, Marko 05 Jul '19

05 Jul '19

Dear oVIrt, Although it should be simple, I am failing to understand the connection between Default Gateway setting and Bad Gateway issue. On which network I need to set default gateway: Our ovirtmgmt is set not to be used by Guest VMs, only Hosted-Engine. We have tenant1 network which is assigned to VM Guest instances and it has Default Gateway, working one 😊. Why am I still seeing this message: 2019-07-04 12:53:08,991Z ERROR [org.ovirt.engine.core.bll.provider.network.SyncNetworkProviderCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-54) [2cfff521] Command 'org.ovirt.engine.core.bll.provider.network.SyncNetworkProviderCommand' failed: EngineException: (Failed with error Bad Gateway and code 5050) What am I doing wrong? If you need more info or log data, just let me know. oVIrt 4.3.3 Kindly awating your reply. Marko Vrgotic ActiveVideo

Re: Anaconda crashing on start while trying to Install oVirt Node on bare metal

If you don't have a raid controller with battery-backed cache - disable the raid in bios. Fake raids are just like software raid, use the cpu for calculations and could be a potential problem if the Motherboard dies. Software raid (controlled by mdadm) and lvm raid (sane driver but controlled from lvm) can easily be recovered on any type of linux (as long as it is not too old ofc) and do not have the minuses of the fake raid.

Re: lvm agregation of lun in a storage domain

I think the simplest way is to get a new LUN and migrate the VM disks to it. Once the 2 old LUNs are free - you can release them both.

I am having issue with adding network to host nic with python SDK. It works just fine using the portal GUI. I have the following: bond0 that is setup as mode 4 bond0.120 that is attached to ovirtmgmt network bond0.96 that I am trying to attach a new installed network called External.

Spice console very poor performance for Windows 10 vm
by Leo David 04 Jul '19

04 Jul '19

Hello Everyone, Maybe I am something wrong, but spice console seem to be very laggy and slow for windows 10 vms. I have tried both qxl and qxl-dod drivers, but no luck so far... As a notice, the Win 2012R2 vm console is running fine, the problem seems to only affect Windows 10. Any ideas, what should I do to sort this out ? Thank you very much !

Using a synology as an nfs storage
by Andy Michielsen 03 Jul '19

03 Jul '19

Hello, I'm setting up a 3 node cluster with the ovirtnode iso and a seperate server with the engine on and a synology for nfs storage. I have done my configuration and I'm able to mount the share manually on the node with a command. Also on the server with the engine on I can mount it manually. But when I want to do it through the webinterface to add a data domain it say the permissions are wrong. Any idea's on how to figure this out ? Kind regards.

Hosted Engine Deploy - Error at the end... [NFS ?]
by csi-laser＠cisco.com 03 Jul '19

03 Jul '19

Hi, While Trying to Deploy Hosted Engine, I'm stuck on Stage 4. Here is the error : [ INFO ] TASK [ovirt.hosted_engine_setup : Fetch Datacenter name] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Add NFS storage domain] [ ERROR ] Verify permission settings on the specified storage path.]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Permission settings on the specified path do not allow access to the storage.\nVerify permission settings on the specified storage path.]\". HTTP response code is 400."} But, it's very strange, because, when I'm trying to mount this NFS share manually, It's working.... So what am I doing wrong here ? Here is the "Storage Connection" - 8.45.119.16:/ovirt_engine Mount option is blanked NFS Version is "v3" Thanks in advance !

network performance issues
by Guy Brodny 02 Jul '19

02 Jul '19

Hello. we have installed Ovirt on HPE ProLiant XL270d Gen10. The server is installed with 2 * Intel(R) Xeon(R) Gold 6154 CPU @ 3.00GHz, 1.5T Ram, 23T Local SSD, 4 Nvidia V100 32GB GPU and 2* Mellanox Technologies MT27800 Family [ConnectX-5] The Mellanox card are 2 100Gbit DualPort each connected with a single 100Gbit port to a Mellanox 100Gbit switch which has access to a 16GByte storage server. MTU is set to 9000 for jumbo packets. Running our application on a VM created on top of the server is having lower network performance vs the host. I tried both normal ovirt network driver, using Virtual Function and PCI-passthrough moving one of the Mellanox card directly to the VM but i never get the same result as on the host. I also tried allocating the numa bush directly to the VM but it doesnt improve the results. Im testing using FIO to perform sequential reads from the storage, this is the command we run both on the host and the VM. sqream@host-3-171 /media/StorONE1/tpch10t_for_4.0/logs/192.168.3.171_5000 $ fio --randrepeat=1 --ioengine=sync --direct=1 --gtod_reduce=1 --name=test --filename=/media/StorONE3/t1e1s1111t221www22.file --bs=2m --iodepth=24 --size=25G --numjobs=14 --readwrite=read --rwmixread=100 Run status group 0 (all jobs): READ: bw=3919MiB/s (4109MB/s), 280MiB/s-314MiB/s (294MB/s-329MB/s), io=350GiB (376GB), run=81630-91459msec Before starting Ovirt i measured 7.5GB/sec on the host running the same FIO command. are there any optimization i should perform to make sure the vguest i getting the best possible network performance, im mostly stressed about GPFS performance as this is our main filesystem. On the same time running the test on another host not running Ovirt i can still get the 7.9GB/sec. appreciate any comments or suggestions.

oVirt node 4.3.4 stable can't deploy hosted engine to iscsi target all available LUNs used
by Mitja Pirih 02 Jul '19

02 Jul '19

Hi, I am new to oVirt, coming from XenServer platform, so please be patient with me. After a successful install of latest stable oVirt node (ovirt-node-ng-installer-4.3.4-2019061016.el7.iso) I am having troubles deploying hosted engine to an iscsi target over Cockpit. I have a couple of iscsi targets available on two different storage platforms (Synology DS418, Lenovo DE2000H). After retrieving iscsi Target list all LUNs get automatically "connected" by "Target list scan" and shown as used on LUNs list. I can reproduce this every single time. On storage system I can also see, that all LUNs get connected by the initial scan. As a result I an unable to continue the deployment as there are no LUNs available. Is this a normal behavior? What would you suggest me to do? Thanks.

Adding a custom fence agent on 4.3.4
by Matteo 02 Jul '19

02 Jul '19

Hi, I'm trying to add a custom fence agent for my test deployment on hetzner. Have written a small fence_hetzner_robot script which works ok from cli and installed on every ovirt node. Then added with engine_config in this way: # engine-config -s CustomVdsFenceType="hetzner_robot" But does not show up in fence agents list under host pm configuration. I'm missing something? thanks! Matteo PS: Also tried to set up an empty param mapping, just to test # engine-config -s CustomVdsFenceOptionMapping="hetzner_robot:" but still nothing.

SPICE and VNC native
by kim.kargaard＠noroff.no 02 Jul '19

02 Jul '19

Hi, We are running ovirt 4.3. The engine is on a bare metal machine and the hosts are running on Centos 7. When installing the engine, I set it to be the webproxy. When I create a new vm, I select both SPICE+VNC. When clicking on the console I only have the option for SPICE native, not for the HTML option. For VNC I have both options and the HTML option can be selected and works. But, this is also the only option that works. VNC Native as well as SPICE Native do not work. I have tried using both remote viewer on Mac and a VNC client on a Windows machine and neither will actually open the VM. I would really also like the SPICE HTML option to exist, but it does not. The enable SPICE proxy in the Console selection is greyed out. When I open in remoteviewer (Mac) I get Unable to connect to the graphic server. Any suggestions? Kim

it seems vgpu state be mistack freed when operating(start and stop) vm at the same time
by weizhengya16＠gmail.com 02 Jul '19

02 Jul '19

We using ovirt in production environment with each virtual machine with a vGpu。but serveral days later, I find several phisical server has been crash and automatic reboot。And I also found some vGpu exist with no virtual machine using. So it makes virtual machine start fail because of lacking resource.I must enter the vgpu directory and using "echo "1" >remove" to free this vGpu。With ceaselessly stop and start, the probability of its occurrence is approximately 0.1%-1%

[ANN] Incubating terraform-provider-ovirt
by Roy Golan 02 Jul '19

02 Jul '19

Hi all, Happy to announce the incubation of a terraform provider[1] for oVirt which is the the result of a community effort started by ESM-MSC institute [2] and then picked up by @imjoey [3] which is now the main maintainer of the project. Terraform with an ovirt provider makes it easy to declaratively create virtualized environments. One usage we will make of it is to create an installer for OKD 4 [4] which will lay an OKD cluster on top of oVirt resources.

I've restarted the engine service. I've checked for zombie tasks with the db utils - none found. Engine is hosted in a HA environment with 2 iron boxes, I have rebooted the hosts that engine is running on. I have migrated hostedengine to both hosts to see if there's an issue perhaps with one of the hosts. No resolution of issue. Been searching for various aspects of the logs to try & get an answer (for quite a few days this issue started some time ago and is in our test environment), all seem to lead to dead ends. hosted-engine --vm-status --== Host 1 (id: 1) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : hostname Host ID : 1 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : a3c24020 local_conf_timestamp : 425 Host timestamp : 425 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=425 (Fri Jun 28 14:06:44 2019) host-id=1 score=3400 vm_conf_refresh_time=425 (Fri Jun 28 14:06:45 2019) conf_on_shared_storage=True maintenance=False state=EngineDown stopped=False --== Host 2 (id: 2) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : hostname Host ID : 2 Engine status : {"health": "good", "vm": "up", "detail": "Up"} Score : 3400 stopped : False Local maintenance : False crc32 : e9a6ca22 local_conf_timestamp : 952 Host timestamp : 952 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=952 (Fri Jun 28 14:06:50 2019) host-id=2 score=3400 vm_conf_refresh_time=952 (Fri Jun 28 14:06:50 2019) conf_on_shared_storage=True maintenance=False state=EngineUp stopped=False Last thing I did before this error showed up was created about 10 servers from a template. There were various lease errors for the servers but they came up and seemed functional. Clearly the issue is here: "Exception in startFailedAutoStartVms" in the "START_ARRAY token" but I can't find anything as of yet that says if you see this - do x,y,z. Learning oVirt so my apologies if this is a 101 question.
