Re: huge page in ovirt 4.2.7
by Sharon Gratch 08 Apr '19

08 Apr '19

Hi Fabrice, The "hugepages" custom property value in oVirt should be set to *size of the pages in KiB* (i.e. 1GiB = 1048576, 2MiB = 2048). In addition, it is recommended to set the huge page size of the VM to the largest size supported by the host. In the configuration you sent, the huge page size of the VM is set to 64 KiB and since the VM's allocated memory size is at least 32,768 MiB then it requires at least (32768 * 1024/64=) 524,288 pages. Since you only have 120 pages declared in the host then it failed with an error "...there are not enough free huge pages to run the VM". So to solve the problem, please change the VM's huge page size to be the same as the host's huge page supported size which is 1GiB and therefore hugepages value should be 1048576 KiB instead of 64: <custom_property> <name>hugepages</name> <value>*1048576*</value> </custom_property> Please note that since total VM's memory size is no more than 64 GB then only 64 pages will be needed by the VM and it's < 120 pages supported by the host and therefore OK. Hope it helped.

4.3 rc2: info about shutdown of last host and networking page
by Gianluca Cecchi 07 Apr '19

07 Apr '19

Hello, env with single host HCI deployment from node ng iso After powering off VMs, put into global maintenance, shutdown hosted engine, I then run shutdown on host. This I think would simulate also a total shutdown scenario when you have the final step of shutdown of the final host. This is what I see in console about failure in several unmounts, both /var and /var/log and also gluster related filesystems Could there be any dependency problem? See here the screenshot: https://drive.google.com/file/d/1wqqXlmT66hHLJ8DMcwfPvDXJHkWm_ijE/view?usp=… Also I have not understood the networking page of host in Cockpit: https://drive.google.com/file/d/1isX4F8qPcFmTyhmCVnZadhp6NY0R9Sy7/view?usp=… in my scenario I was downloading a 1Gb image for the CentOS Atomic host from public glance repo. Questions: - how to explain the receiving box graph? What are the different color lines for? - In "receiving" column inside the "interfaces" sections I see all "0" for gluster one (eth1) and empty (no value) for ovirtmgmt (perhaps because it is unmanaged from host point of view?) Also, it seems to me that the temporary bridge for hosted engine deployment on 192.168.124.0 (virbr0) is still there even after finishing the deployment, even if with "no carrier"... is this expected? Better perhaps to undefine the network after deployment? Gianluca

Agentless Backup update: Trilio Vault...what a joke, pay $7500
by femi adegoke 07 Apr '19

07 Apr '19

Back in June of 2018, I posted regarding Agentless backup solutions. Greg Sheremeta replied & mentioned Trilio. The rest of the story...well just read on... These guys at Trilio have turned out to be a complete waste of time. (I could use some more colorful language) After my post & reply from Greg Sheremeta, I followed up with Trilio. A lot of promises/dates were made (by Trilio) as to when a beta would be made available for testing. Needless to say, they never came through. Finally in Dec 2018, they said we are ready for the demo, we will show you a working product. The day came, Trilio said, sorry it's too close to Xmas, we will postpone the demo's till 2019. In 2019, I continued to follow up & finally they set a date for another demo - Jan 29. On Jan. 29, we get on the Webex, they said, sorry the demo just broke 10 mins prior to our call, so no demo. They show me some screenshots & their OpenStack version & again promise to get me beta software in a few days. I continue to follow up (via email) Yesterday (Feb 6), I get an email from Thomas Lahive GM; Sales and Alliance Partners....(copied & pasted below): "We started RHV betas and decided to prioritize current Trilio customers (those that purchased Triliovault for Openstack). If you would like to be part of the beta now then We can sign you up as a certified Trilio reseller which has a $7,500 Starter Fee. The $7,500 will be credited against your first customer order that is at least $7,500 so it will eventually cost you nothing. Many of our partners can apply the fee against revenue so it's a great tax incentive, but you can confirm with your finance department. Please Lmk how you would like to proceed." Please remember, I have never seen a working demo of this product, never. Is this typical behavior of RH partners?

Hosted Engine Storage migration
by joel+ovirt＠robisons.us 25 Mar '19

25 Mar '19

Hello listmembers! I'm in search of some steps to use to migrate my Hosted-Engine from one NFS storage domain to another different NFS storage domain. One of the possible ways to accomplish this task may already be a feature with oVirt 4.1, I'm using 4.2 https://lists.ovirt.org/pipermail/users/2017-January/078739.html (New feature in 4.1?) Will someone elaborate the steps to use this new feature and how I could use it to accomplish this task? the bug link in the email linked above has a comment (https://bugzilla.redhat.com/show_bug.cgi?id=1409112#c12) - does this mean I need to redeploy the hosted-engine? I'm not able to follow as I'm new to oVirt and still learning the ins and outs and design if I'm on the wrong path here please correct me. Thank you, -Joel

Error creating a storage domain (On Cisco UCS Only)
by nico.kruger＠darkmatter.ae 18 Mar '19

18 Mar '19

Hi Guys, I am trying to install a new cluster... I currently have a 9 node and two 6 node oVirt Clusters... (these were installed on 4.1 and upgraded to 4.2) So i want to build a new cluster, which is working fine on this HP notebook i use for testing (using single node gluster deployment) But when i try install this on my production servers which are Cisco UCS servers i keep getting this error: [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Error creating a storage domain]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Error creating a storage domain]\". HTTP response code is 400."} This happens during storage creation after the hosted-engine is built and after gluster has been deployed (error happens for both single and 3 replica deployments) I just cant see how an install on one type of server is successful but not on the UCS servers (which i am running my other ovirt clusters on) BTW i dont think the issue is related to Gluster Storage Create as i tried using NFS and Local storage and get the same error (on UCS server only) I am using the ovirt-node-ng-installer-4.2.0-2019011406.el7.iso install ISO Below is a tail from ovirt-hosted-engine-setup-ansible-create_storage_domain Log file 2019-01-27 11:09:49,754+0400 INFO ansible ok {'status': 'OK', 'ansible_task': u'Fetch Datacenter name', 'ansible_host': u'localhost', 'ansible_playbook': u'/usr/share/ovirt-hosted-engine-setup/ansible/create_storage_domain.yml', 'ansible_type': 'task'} 2019-01-27 11:09:49,754+0400 DEBUG ansible on_any args <ansible.executor.task_result.TaskResult object at 0x7f9f9b7e2d50> kwargs 2019-01-27 11:09:50,478+0400 INFO ansible task start {'status': 'OK', 'ansible_task': u'Add NFS storage domain', 'ansible_playbook': u'/usr/share/ovirt-hosted-engine-setup/ansible/create_storage_domain.yml', 'ansible_type': 'task'} 2019-01-27 11:09:50,479+0400 DEBUG ansible on_any args TASK: Add NFS storage domain kwargs is_conditional:False 2019-01-27 11:09:51,151+0400 DEBUG var changed: host "localhost" var "otopi_storage_domain_details_nfs" type "<type 'dict'>" value: "{ "changed": false, "skip_reason": "Conditional result was False", "skipped": true }" 2019-01-27 11:09:51,151+0400 INFO ansible skipped {'status': 'SKIPPED', 'ansible_task': u'Add NFS storage domain', 'ansible_host': u'localhost', 'ansible_playbook': u'/usr/share/ovirt-hosted-engine-setup/ansible/create_storage_domain.yml', 'ansible_type': 'task'} 2019-01-27 11:09:51,151+0400 DEBUG ansible on_any args <ansible.executor.task_result.TaskResult object at 0x7f9f9b7e2610> kwargs 2019-01-27 11:09:51,820+0400 INFO ansible task start {'status': 'OK', 'ansible_task': u'Add glusterfs storage domain', 'ansible_playbook': u'/usr/share/ovirt-hosted-engine-setup/ansible/create_storage_domain.yml', 'ansible_type': 'task'} 2019-01-27 11:09:51,821+0400 DEBUG ansible on_any args TASK: Add glusterfs storage domain kwargs is_conditional:False 2019-01-27 11:10:02,045+0400 DEBUG var changed: host "localhost" var "otopi_storage_domain_details_gluster" type "<type 'dict'>" value: "{ "changed": false, "exception": "Traceback (most recent call last):\n File \"/tmp/ansible_ovirt_storage_domain_payload_Xous24/__main__.py\", line 682, in main\n ret = storage_domains_module.create()\n File \"/tmp/ansible_ovirt_storage_domain_payload_Xous24/ansible_ovirt_storage_domain_payload.zip/ansible/module_utils/ovirt.py\", line 587, in create\n **kwargs\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/services.py\", line 24225, in add\n return self._internal_add(storage_domain, headers, query, wait)\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 232, in _internal_add\n return future.wait() if wait else future\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 55, in wait\n return self._code(response)\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 229, in callback\n self._check_fault(response)\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 132, in _check_fault\n self._raise_error(response, body)\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 118, in _raise_error\n raise error\nError: Fault reason is \"Operation Failed\".

Hi, Based on oVirt 4.3.0, I have data domain from FC lun, then I create new vm on the disk from FC data domain. After VM was created. According to qemu-img info, the disk size is 0. # qemu-img info /rhev/data-center/mnt/blockSD/eaa6f641-6b36-4c1d-bf99-6ba77df3156f/images/8d3b455b-1da4-49f3-ba57-8cda64aa9dc9/949fa315-3934-4038-85f2-08aec52c1e2b image: /rhev/data-center/mnt/blockSD/eaa6f641-6b36-4c1d-bf99-6ba77df3156f/images/8d3b455b-1da4-49f3-ba57-8cda64aa9dc9/949fa315-3934-4038-85f2-08aec52c1e2b file format: raw virtual size: 10G (10737418240 bytes) disk size: 0 I tried on iscsi and same result. Is the behaviour expected? Thanks, Jingjie

oVirt Performance (Horrific)
by drew.rash＠gmail.com 13 Mar '19

13 Mar '19

Hi everybody, my coworker and I have some decent hardware that would make great single servers, and then we through in a 10gb switch with 2x10gbps cards in 4 boxes. We have 2 excellent boxes - super micro board (disabled speed step) with 14 core intel i9's 7940x's, 128 GB ram (3200), 1tb m.2 samsung 870 evo's, 1tb ssd samsung, 1 8TB WD Gold, 1 6TB WD gold. Then we have 2 boxes (1 with 8 core i7-9700k, 1 with 6 core i7-8700) 128GB ram in one, 64GB ram in the other all 3000MHz with the same 1tb ssd,6tb wd gold, 8tb wd gold drives as the other boxes and 10gbps cards. Our problem is performance. We used the slower boxes for KVM(libvirt) and FreeNAS at first which was great performance wise. Then we bought the new super micro boxes and converted to oVirt + Gluster and did some basic write test using dd writing zero's to files from 1GB up to 50GB and were happy with the numbers writing directly to the gluster. But then we stuck a windows VM on it and turned it on...I'll stop there..because turning it on stopped any performance testing. This thing blew goat cheese. It was so slow the oVirt guest agent doesn't even start along with MS SQL server engine sometimes and other errors. So naturally, we removed the gluster from the equation. We took one of the 8TB WD Gold drives, made it a linux NFS share and gave it to oVirt to put VM's on as an NFS Domain. Just a single drive. Migrated the disk with the fresh windows 10 installation to it configured as VirtIO-SCSI, and booted the vm with 16GB ram, 8:1:1 cpu's. To our surprise it still blew. Just ran a winsat disk -drive c: for example purposes and the spice viewer repeatedly freezing, had the resource monitor open watching the 10,000ms disk response times with results...results were I rebooted because the results disappeared I didn't run it as administrator. And opening a command prompt is painful, the disk is still in use The task manager has no words on it. Disk is writing like 1MBps. command prompt finally showed up and looked blank with the cursor offset with no words anywhere. So the reboot took .. Well turning off took 2 minutes. Booting took 6 minutes 30 seconds ish. Logging in: 1m+ So 9-10 minutes to reboot and log back in a fresh windows install. Then 2 minutes to open a command prompt, task manager and resource monitor. During the write test disk i/o on the vm was less than 8, from the graph looks like 6MBps. Network traffic is like 20Mbps average, cpu is near zero, a couple spikes up to 30MBps on the disk. I ran this same thing on my disk and it finished in <1m. Ran it on the vm...still running after 30 minutes. I'll wait for the results to post them here. Ok It's been 30 minutes and it's still writing. I don't see the writes in the resource monitor, windows is doing a bunch of random app updates or something with candy crush on a fresh install and, ok so I hit enter a bunch of times on the prompt and it moved down to a flush-seq...and now it shows up in the resource monitor doing something again...I just ran this on my pc and it finished in less than a minute... whatever it's doing it's almost running at 1MB/s I think something went wrong because it only shows like 2 minutes passing at any test and then a total of 37 minutes. And at no time did the windows resource graphs or any of the oVirt node system graphs show more than like 6MB/s and definitely not 50 or 1GBps... flat out lies here.

So I'll try copying a file from a 1gbps network location with an ssd to this pc. It's a 4GB CentOS7 ISO to the desktop. It said 20MB/s then up to 90MB/s...then it dropped after doing a couple gigs. 2.25 gigs to go and it's going at 2.7MB/s with some fluctuations up to 5MB. So to drive this home at the same time... I copied the file off the same server to another server with ssd disks and it ran at 100MB/s which is what I'd expect over a 1gbps network. All this said, we do have an ssd gluster 2+1 arbiter (which seemed fastest when we tested different variations) on the 1TB ssd's. I was able to do reads from the array inside a VM at 550MB/s which is expected for an ssd. We did dd writing zero's and got about 550MB/s also from the ovirt node. But inside a VM the best we get is around ~10MB/s writing. Basically done the same testing using windows server 2016, boot terrible, opening applications terrible. But with sql server running off the ssd gluster I can read at 550MB/s but writing is horrific somewhere around 2-10MB/s. Latency between the nodes with ping is 100us ish. The hardware should be able to do 200MB/s HDD's, 550MB/s SSD's but it doesn't. And it's evident in every writing scenario inside a vm. Migrating VM's is also at this speed. Gluster healing seems to run faster, we've seen it conusme 7-9 Gbps. So I feel this is an oVirt issue and not gluster. Especially since all the tests above are the same when using an NFS mount on the box running the VM in oVirt. Please guide me. I can post pictures and such if needed, logs whatever. Just ask.

Suggestions on adding 1000 or more networks to an engine/hosts
by Brian Wilson 12 Mar '19

12 Mar '19

So we have a use case where our engines will will be hosting development sandbox clusters. We need to have upwards of 1000 networks on some of these. I understand there is no theoretical limit to the number of networks does any body have a good reliable way of instantiating all of these networks. We have been using ansible for POCs and doing 100 Networks have not had a problem getting them on there however when upping the number to many more it begins to take longer and longer between each one and eventually timed iout and only got to 1567 Example Task we are using for this: tasks: - name: Add More Networks ovirt_network: auth: "{{ ovirt_auth }}" data_center: "{{ pcloud_name }}" name: "{{ pcloud_name }}-{{ item }}" state: present label: uplink vlan_tag: "{{ item }}" clusters: - name: "{{ ovirt_cluster }}" assigned: yes required: no display: no migration: no gluster: no with_sequence: start=1551 end=2500 What are some better ways of bulk additions of networks? Would the API provide a better solution so as to sorta bulk cache them then initiate the save?

Ovirt Node 4.3 Gluster Install adding bricks
by pollard＠tx.net 11 Mar '19

11 Mar '19

Sorry if this seems simple, but trial and error is how I learn. So the basics. I installed Node 4.3 on 3 hosts, and was following the setup for self-hosted engine. The setup fails when detecting peers and indicates that they are already part of a cluster. So i restart the install and choose the install engine on single node with Gluster. I now have all three nodes connected to ovirt engine, however my trouble is I am not understanding how to add the disk of the two nodes to the glusterFS. I also have some extra disks on my primary node I want to add. I believe it is as follows but I dont want to mess this up. Under Compute >> Hosts >> $HOSTNAME Select Storage Devices Select Disk in my case sde Then create brick? If this is the case Do I add it to a LV if so which one engine,data or vmstore? Do I repeat this for each hosts? I can duplicate the engine, data and vmstore on each one, but that will still leave me with two disks on each node without assignment If anyone can help that would be great. Thank you. Pollard

Unable to make Single Sign on working on Windows 7 Guest
by Felipe Herrera Martinez 11 Mar '19

11 Mar '19

On the case I'll be able to create an installer, what is the name of the Application need to be there, in order to ovirt detects that Ovirt Guest agent is installed? I have created an installer adding OvirtGuestService files and the Product Name to be shown, a part of the command line post installs.. I have tried with "ovirt-guest-agent" and "Ovirt guest agent" Names for the application installed on Windows 7 guest and even both are presented on ovirt VM Applications tab, on any case LogonVDScommand appears. There is other option to make it work now? Thanks in advance, Felipe

Infiniband Usage / Support
by Andrey Rusakov 08 Mar '19

08 Mar '19

Hi, I got a config with IB Storage (IPoIB). I would like to extend IB usage to OVN network, but trying to do this i find some problems ... Problem #1 (IPoIB Storage Network) I configure IPoIB Before adding to oVirt cluster (I did it using Cockpit) Create [Bond], assign IP, change MTU. At this moment of time everything is fine... But - I am not able to assign IP/MTU using oVirt Cluster. And I can't perform any changes using Cockpit as IB interfaces are "Unmanaged Interfaces". Problem #1.1 It will be great to avoid users adding IPoIB networks using brctl, as it will not work... Problem #2 What is correct way to move OVN to IPoIB network?

Please don't remove instance type
by Baptiste Agasse 07 Mar '19

Hi all, We are happy oVirt users for some years now (we started with 3.6, now on 4.2) and we manage most of our virtualization stacks with it. To provision and manage our machines, we use the foreman (for bare metal and virtual machines) on top of it. I made some little contributions to the foreman and other underlying stuff to have a deeper integration with oVirt, like to be able to select instance type directly from foreman interface/api and we rely on it. We use instance types to standardize our vms by defining system resources (memory, cpu and cpu topology) console type, boot options. On top of that we plan to use templates to apply OS (CentOS 7 and CentOS 6 actually). Having resources definitions separated from OS installation help us to keep instance types and templates lists small and don't bother users about some technical underlying stuff. As we are interested in automating oVirt maintenance tasks and configuration with ansible, I asked at FOSDEM oVirt booth if there is any ansible module to manage instance types in Ovirt as I didn't find it in ovirt ansible infra repo. The person to whom I asked the question said that you are planning to remove instance types from ovirt, and this make me sad :(. So here I am to ask why do you plan to remove instance types from oVirt. As far as I know, it's fairly common to have "instance types" / "flavors" / "sizes" on one side and then templates (bare OS, preinstalled appliances...) on other side and pick one of each to make an instance. If this first part is missing in future version of ovirt, it will be a pain point for us. So, my question is, do you really plan to remove instances type definitely ? Cheers. -- Baptiste

Quota Actual Consumption
by Andrey Rusakov 06 Mar '19

Hi, Is it possible to configure oVirt to work Quota with actual vCPU Consumption. Currently i got 1 VM with 2 vCPU and 8Gb. In VM stats - 0% of CPU in use 0% of RAM in Use (it is fresh Linux instalaltion) In Quota consumption i can see 40% of CPU (vCPU quota = 5) 27% of RAM (Memory quota 30Gb) Is it possible to adjust Quata management to work with Actual workload, instead of VM Configuration? P.S. Seems like it is working for Storage, as i can see 0% Consumption in Quota (1Gb of thick disk with 20Gb Max and 200Gb in Quota)
