numa pinning and reserved hugepages (1G) Bug in scheduler calculation or decision ?
by Ralf Schenk 24 Aug '19

24 Aug '19

Hello List, i ran into problems using numa-pinning and reserved hugepages. - My EPYC 7281 based Servers (Dual Socket) have 8 Numa-Nodes each having 32 GB of memory for a total of 256 GB System Memory - I'm using 192 x 1 GB hugepages reserved on the kernel cmdline default_hugepagesz=1G hugepagesz=1G hugepages=192 This reserves 24 hugepages on each numa-node. I wanted to pin a MariaDB VM using 32 GB (Custom Property hugepages=1048576) to numa-nodes 0-3 of CPU-Socket 1. Pinning in GUI etc. no problem. When trying to start the vm this can't be done since ovirt claims that the host can't fullfill the memory requirements - which is simply not correct since there were > 164 hugepages free. It should have taken 8 hugepages from each numa node 0-3 to fullfill the 32 GB Memory requirement. I also freed the system completely from other VM's but that didn't work either. Is it possible that the scheduler only takes into account the "free memory" (as seen in numactl -H below) *not reserved* by hugepages for its decisions ? Since the host has only < 8 GB of free mem per numa-node I can understand that VM was not able to start under that condition. VM is runnig and using 32 hugepages without pinning but a warning states "VM dbserver01b does not fit to a single NUMA node on host myhost.mydomain.de. This may negatively impact its performance. Consider using vNUMA and NUMA pinning for this VM." This is the numa Hardware Layout and hugepages usage now with other VM's running: from cat /proc/meminfo HugePages_Total: 192 HugePages_Free: 160 HugePages_Rsvd: 0 HugePages_Surp: 0 I can confirm that also under the condition of running other VM's there are at least 8 hugepages free for each numa-node 0-3: grep "" /sys/devices/system/node/*/hugepages/hugepages-1048576kB/free_hugepages /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/free_hugepages:8 /sys/devices/system/node/node1/hugepages/hugepages-1048576kB/free_hugepages:23 /sys/devices/system/node/node2/hugepages/hugepages-1048576kB/free_hugepages:20 /sys/devices/system/node/node3/hugepages/hugepages-1048576kB/free_hugepages:22 /sys/devices/system/node/node4/hugepages/hugepages-1048576kB/free_hugepages:16 /sys/devices/system/node/node5/hugepages/hugepages-1048576kB/free_hugepages:5 /sys/devices/system/node/node6/hugepages/hugepages-1048576kB/free_hugepages:19 /sys/devices/system/node/node7/hugepages/hugepages-1048576kB/free_hugepages:24 numactl -h: available: 8 nodes (0-7) node 0 cpus: 0 1 2 3 32 33 34 35 node 0 size: 32673 MB node 0 free: 3779 MB node 1 cpus: 4 5 6 7 36 37 38 39 node 1 size: 32767 MB node 1 free: 6162 MB node 2 cpus: 8 9 10 11 40 41 42 43 node 2 size: 32767 MB node 2 free: 6698 MB node 3 cpus: 12 13 14 15 44 45 46 47 node 3 size: 32767 MB node 3 free: 1589 MB node 4 cpus: 16 17 18 19 48 49 50 51 node 4 size: 32767 MB node 4 free: 2630 MB node 5 cpus: 20 21 22 23 52 53 54 55 node 5 size: 32767 MB node 5 free: 2487 MB node 6 cpus: 24 25 26 27 56 57 58 59 node 6 size: 32767 MB node 6 free: 3279 MB node 7 cpus: 28 29 30 31 60 61 62 63 node 7 size: 32767 MB node 7 free: 5513 MB node distances: node 0 1 2 3 4 5 6 7 0: 10 16 16 16 32 32 32 32 1: 16 10 16 16 32 32 32 32 2: 16 16 10 16 32 32 32 32 3: 16 16 16 10 32 32 32 32 4: 32 32 32 32 10 16 16 16 5: 32 32 32 32 16 10 16 16 6: 32 32 32 32 16 16 10 16 7: 32 32 32 32 16 16 16 10 -- *Ralf Schenk* fon +49 (0) 24 05 / 40 83 70 fax +49 (0) 24 05 / 40 83 759 mail *rs(a)databay.de* <mailto:rs@databay.de> *Databay AG* Jens-Otto-Krag-Straße 11 D-52146 Würselen *www.databay.de* <http://www.databay.de> Sitz/Amtsgericht Aachen • HRB:8437 • USt-IdNr.: DE 210844202 Vorstand: Ralf Schenk, Dipl.-Ing.

Need to enable STP on ovirt bridges
by ej.albany＠gmail.com 23 Aug '19

23 Aug '19

Hello. I have been trying to figure out an issue for a very long time. That issue relates to the ethernet and 10gb fc links that I have on my cluster being disabled any time a migration occurs. I believe this is because I need to have STP turned on in order to participate with the switch. However, there does not seem to be any way to tell oVirt to stop turning it off! Very frustrating. After entering a cronjob that enables stp on all bridges every 1 minute, the migration issue disappears.... Is there any way at all to do without this cronjob and set STP to be ON without having to resort to such a silly solution? Here are some details about my systems, if you need it. selinux is disabled.

Migration from bare metal engine to hosted doesn't seem to work at all in 4.3.2
by Clinton Goudie-Nice 23 Aug '19

23 Aug '19

Hi all, I'm trying to migrate from an ovirt bare metal instance to the hosted appliance. The instructions here: https://www.ovirt.org/documentation/self-hosted/chap-Migrating_from_Bare_Me… are at best murky, and at worst quite wrong, and I'm looking for some help. The instructions say "You must answer No to the following question so that you can restore the BareMetal-Engine backup file on HostedEngine-VM before running engine-setup. Automatically execute engine-setup on the engine appliance on first boot (Yes, No)[Yes]? No" Makes complete sense, except this question is not asked at all. Some research on the internet says we should be able to do this via append-answers: [environment:default] OVEHOSTED_VM/cloudinitExecuteEngineSetup=bool:False Except this doesn't work either. When the appliance deploys the engine is setup and already running. How do I take a backup file, and a backup log, and deploy them into a hosted engine? Clint

Creating hosts via the REST API using SSH Public Key authentication
by schill-julian＠gmx.de 23 Aug '19

23 Aug '19

In the UI one can create hosts using two authentication methods: 'Password' and 'SSH Public Key'. I have only found the Password authentication in the API Docs (/ovirt-engine/apidoc/#/services/hosts/methods/add). My question is: How can i create hosts using SSH Public Key authentication via the REST API? I would appreciate an example POST request!

nodectl on plain CentOS hypervisors
by Gianluca Cecchi 23 Aug '19

23 Aug '19

Does it make sense to install nodectl utility on plain CentOS 7.x nodes? Or any other alternative for plain OS nodes vs ovirt-node-ng ones? On my updated CentOS 7.6 oVirt node I have not the command; I think it is provided by the package ovirt-node-ng-nodectl, that is one of the available ones if I run "yum search" on the system. Thanks Gianluca

oVirt 3.6: Node went into Error state while migrations happening
by Christopher Cox 23 Aug '19

23 Aug '19

On the node in question, the metadata isn't coming across (state) wise. It shows VMs being in an unknown state (some are up and some are down), some show as migrating and there are 9 forever hung migrating tasks. We tried to bring up some of the down VMs that had a state of Down, but that ended up getting them the state of "Wait for Lauch", though those VMs are actually started. Right now, my plan is attempt a restart of vdsmd on the node in question. Just trying to get the node to a working state again. There a total of 9 nodes in our cluster, but we can't manage any VMs on the affected node right now. Is there a way in 3.6 to cancel the hung tasks? I'm worried that if vdsmd is restarted on the node, the tasks might be "attempted"... I really need them to be forgotten if possible. Ideally want all "Unknown" to return to either an "up" or "down" state (depending if the VM is up or down) and for "Wait for Launch" for those, to go to "up" and for all the "Migrating" to go to "up" or "down" (I think only one is actually down). I'm concerned that any attempt manually maniplate the state in the ovirt mgmt head db will be moot because the node will be queried for state and that state will be taken and override anything I attempt to do. Thoughts??

large size OVA import fails

I have a fairly large OVA (~200GB) that was exported from oVirt4.3.5. I'm trying to import it into a new cluster, also oVirt4.3.5. The import starts fine but fails again and again. Everything I can find online appears to be outdated, mentioning incorrect log file locations and saying virt-v2v does the import. On the engine in /var/log/ovirt-engine/engine.log I can see where it is doing the CreateImageVDSCommand, then a few outputs concerning adding the disk, which end with USER_ADD_DISK_TO_VM_FINISHED_SUCCESS, then the ansible command: 2019-08-20 15:40:38,653-04 Executing Ansible command: /usr/bin/ansible-playbook --ssh-common-args=-F /var/lib/ovirt-engine/.ssh/config -v --private-key=/etc/pki/ovirt-engine/keys/engine_id_rsa --inventory=/tmp/ansible-inventory8416464991088315694 --extra-vars=ovirt_import_ova_path="/mnt/vm_backups/myvm.ova" --extra-vars=ovirt_import_ova_disks="['/rhev/data-center/mnt/glusterSD/myhost.mydomain.com:_vmstore/59502c8b-fd1e-482b-bff7-39c699c196b3/images/886a3313-19a9-435d-aeac-64c2d507bb54/465ce2ba-8883-4378-bae7-e231047ea09d']" --extra-vars=ovirt_import_ova_image_mappings="{}" /usr/share/ovirt-engine/playbooks/ovirt-ova-import.yml [Logfile: /var/log/ovirt-engine/ova/ovirt-import-ova-ansible-20190820154038-myhost.mydomain.com-25f6ac6f-9bdc-4301-b896-d357712dbf01.log] Then nothing about the import until: 2019-08-20 16:11:08,859-04 INFO [org.ovirt.engine.core.bll.exportimport.ImportVmFromOvaCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-88) [3321d4f6] Lock freed to object 'EngineLock:{exclusiveLocks='[myvm=VM_NAME, 464a25ba-8f0a-421d-a6ab-13eff67b4c96=VM]', sharedLocks=''}' 2019-08-20 16:11:08,894-04 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-88) [3321d4f6] EVENT_ID: IMPORTEXPORT_IMPORT_VM_FAILED(1,153), Failed to import Vm myvm to Data Center Default, Cluster Default I've found the import logs on the engine, in /var/log/ovirt-engine/ova, but the ovirt-import-ova-ansible*.logs for the imports of concern only contain: 2019-08-20 19:59:48,799 p=44701 u=ovirt | Using /usr/share/ovirt-engine/playbooks/ansible.cfg as config file 2019-08-20 19:59:49,271 p=44701 u=ovirt | PLAY [all] ********************************************************************* 2019-08-20 19:59:49,280 p=44701 u=ovirt | TASK [ovirt-ova-extract : Run extraction script] ******************************* Watching the host selected for the import, I can see the qemu-img convert process running, but then the engine frees the lock on the VM and reports the import as having failed. However, the qemu-img process continues to run on the host. I don't know where else to look to try and find out what's going on and I cannot see anything that says why the import failed. Since the qemu-img process on the host is still running after the engine log shows the lock has been freed and import failed, I'm guessing what's happening is on the engine side. Looking at the time between the start of the ansible command and when the lock is freed it is consistently around 30 minutes. # first try 2019-08-20 15:40:38,653-04 ansible command start 2019-08-20 16:11:08,859-04 lock freed 31 minutes # second try 2019-08-20 19:59:48,463-04 ansible command start 2019-08-20 20:30:21,697-04 lock freed 30 minutes, 33 seconds # third try 2019-08-21 09:16:42,706-04 ansible command start 2019-08-21 09:46:47,103-04 lock freed 30 minutes, 45 seconds With that in mind, I took a look at the available configuration keys from engine-config --list. After getting each the only one set to ~30 minutes and looks like it could be the problem was SSHInactivityHardTimeoutSeconds (set to 1800 seconds). I set it to 3600 and tried the import again, but it still failed at ~30 minutes, so that's apparently not the correct key. Also, just FYI, I also tried to import the ova using virt-v2v, but that fails immediately: virt-v2v: error: expecting XML expression to return an integer (expression: rasd:Parent/text(), matching string: 00000000-0000-0000-0000-000000000000) If reporting bugs, run virt-v2v with debugging enabled and include the complete output: virt-v2v -v -x [...] Does virt-v2v not support OVAs created by the oVirt 'export to ova' option? So my main question is, Is there a timeout for VM imports through the engine web UI? And if so, is if configurable? Thanks in advance.

Hello I the latest release of the engine 4.3.5.5-1.el7 ovn-nbctl show ovn-sbctl show both seem to work but produce the errors net_mlx5: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory net_mlx5: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx5) PMD: net_mlx4: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory PMD: net_mlx4: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx4) should libibverbs be a dependency?
