which cpu type should I chose ??
by tommy 22 Jul '20

22 Jul '20

Hi: 1.My server using as ovirt host is built on virtualbox and the cpu info is: vendor_id : GenuineIntel cpu family : 6 model : 142 model name : Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz stepping : 10 cpu MHz : 1992.002 cache size : 8192 KB physical id : 0 siblings : 3 core id : 2 cpu cores : 3 apicid : 2 initial apicid : 2 fpu : yes fpu_exception : yes cpuid level : 22 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx rdtscp lm constant_tsc rep_good nopl xtopology nonstop_tsc cpuid tsc_known_freq pni pclmulqdq vmx ssse3 cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt aes xsave avx rdrand hypervisor lahf_lm abm 3dnowprefetch invpcid_single pti tpr_shadow flexpriority fsgsbase avx2 invpcid rdseed clflushopt md_clear flush_l1d bugs : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds swapgs itlb_multihit srbds bogomips : 3984.00 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual power management: 2.On the ovirt host page it appears that the host is unusable.The log info is: Host ohost3 moved to Non-Operational state as host does not meet the cluster's minimum CPU level.

4.4: Export as OVA always fails w/ ACTION_TYPE_FAILED_INVALID_OVA_DESTINATION_FOLDER

Hello all, I'm trying to export a VM as OVA on a single host hyper converged (over NFS) 4.4 installation, and no matter which host destination directory I set, with or without a trailing '/' (per bugzilla #1780424) the export fails with the same error (see below).

Reinstall failed on 4.4.1.1 with custom kernel settings
by mmarino＠extraordy.com 22 Jul '20

22 Jul '20

Hi, after the upgrade from 4.4.1 to 4.4.1.1, it seems that I cannot reinstall adding custom kernel settings. In my case, I'm trying to add "ixgbe.allow_unsupported_sfp=1" to cmdline but reinstall process fails without showing any relevant error in /var/log/vdsm/vdsm.log. I did the same test on version 4.4.1 and it works without problems. On version 4.4.1 I tried to (1) add a parameter with reinstall, (2) add a second parameter and reinstall, (3) remove all params and reinstall and (4) finally add only one custom param with reinstall. All tests are ok on version 4.4.1 and the problem happens only on version 4.4.1.1. Please, have you some idea on how to solve the issue? Is this a bug? Thank you, Marco

I've exported a VM as OVA and now I'm trying to import it in another Data Center (it's like a DR Data Center) Import runs successfully both from GUI and from Ansible, but imported VM disks are empty and the VM fails to boot. How can I import disks content too? Thanks in advance for any help. Paolo

ovirt 4.4 installation issues
by Markus Schaufler 21 Jul '20

21 Jul '20

Hi all, in our environment, CentOS7 and RHEL7 for the most part (Ovirt 4.3 and RHV 4.3), we are able to set a proxy directly in /etc/yum.conf (or on the single repo) to momentarily bypass some network restrictions. The proxy settings looks like this: proxy=http://our-proxy.domain:8080 proxy_username=user proxy_password=password But is also works properly when it is set directly from CLI, and this is the one we use more often: export http_proxy=http://user:password@our-proxy.domain:8080 export https_proxy=https://user:password@our-proxy.domain:8080 We are having difficulties to set the same proxy on CentOS8 / Ovirt 4.4.x. There is no way the proxy settings allows us to run "yum update". Extra Packages for Enterprise Linux 8 - x86_64 0.0 B/s | 0 B 00:00 Errors during downloading metadata for repository 'ovirt-4.4-epel': - Curl error (56): Failure when receiving data from the peer for https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=st… [Received HTTP code 407 from proxy after CONNECT] Error: Failed to download metadata for repo 'ovirt-4.4-epel': Cannot prepare internal mirrorlist: Curl error (56): Failure when receiving data from the peer for https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=st… [Received HTTP code 407 from proxy after CONNECT] Can somebody maybe point us to a solution? The above command is extracted by 'yum update' after a clean installation of Ovirt 4.4.1-2020070811 (but the same issue happened on previous versions and Nightly versions too). Thank you, Markus

Slow ova export performance

Hi All, I'm facing a really slow export ov vms hosted on a single node cluster, in a local storage. The Vm disk is 600 GB and the effective usage is around 300 GB.

Can anyone help me? Thanks in advance Luigi

oVirt install questions
by David White 20 Jul '20

20 Jul '20

I'm reading through all of the documentation at https://ovirt.org/documentation/, and am a bit overwhelmed with all of the different options for installing oVirt. My particular use case is that I'm looking for a way to manage VMs on multiple physical servers from 1 interface, and be able to deploy new VMs (or delete VMs) as necessary. Ideally, it would be great if I could move a VM from 1 host to a different host as well, particularly in the event that 1 host becomes degraded (bad HDD, bad processor, etc...) I'm trying to figure out what the difference is between an oVirt Node and the oVirt Engine, and how the engine differs from the Manager. I get the feeling that `Engine` = `Manager`. Same thing. I further think I understand the Engine to be essentially synonymous with a vCenter VM for ESXi hosts. Is this correct? If so, then what's the difference between the `self-hosted` vs the `stand-alone` engines? oVirt Engine requirements look to be a minimum of 4GB RAM and 2CPUs. oVirt Nodes, on the other hand, require only 2GB RAM. Is this a requirement just for the physical host, or is that how much RAM that each oVirt node process requires? In other words, if I have a physical host with 12GB of physical RAM, will I only be able to allocate 10GB of that to guest VMs? How much of that should I dedicated to the oVirt node processes? Can you install the oVirt Engine as a VM onto an existing oVirt Node? And then connect that same node to the Engine, once the Engine is installed? Reading through the documentation, it also sounds like oVirt Engine and oVirt Node require different versions of RHEL or CentOS. I read that the Engine for oVirt 4.4.0 requires RHEL (or CentOS) 8.2, whereas each Node requires 7.x (although I'll plan to just use the oVirt Node ISO). I'm also wondering about storage. I don't really like the idea of using local storage, but a single NFS server would also be a single point of failure, and Gluster would be too expensive to deploy, so at this point, I'm leaning towards using local storage. Any advice or clarity would be greatly appreciated. Thanks, David Sent with ProtonMail Secure Email.

Info on transporting a gluster storage domain
by Gianluca Cecchi 19 Jul '20

19 Jul '20

Hello, I have env1 and env2, both in 4.3 and both configured as single host HCI environments. On both I have the predefined hosted_storage, data and vmstore gluster storage domains. On env1 I have hosted_storage and data on a disk, and vmstore on a whole different disk. I also have a "big2" gluster storage domain created in another disk in a second time. I want to scratch env1 but preserve and then import vmstore and big2 storage domains in env2 This "big2" is configured as a PV on the whole 4Tb disk on env1. - nvme1n1 4Tb gluster_vg_4t2 serial: BTLF72840DVK4P0DGN eui.01000000010000005cd2e45c02de4d51 dm-3 NVME,INTEL SSDPEDKX040T7 size=3.6T features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 1:0:1:0 nvme1n1 259:3 active undef running [root@ovirt ~]# pvs /dev/mapper/eui.01000000010000005cd2e45c02de4d51 PV VG Fmt Attr PSize PFree /dev/mapper/eui.01000000010000005cd2e45c02de4d51 gluster_vg_4t2 lvm2 a-- <3.64t 0 [root@ovirt ~]# [root@ovirt ~]# lvs gluster_vg_4t2 LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert gluster_lv_big2 gluster_vg_4t2 Vwi-aot--- <4.35t my_pool 1.36 my_pool gluster_vg_4t2 twi-aot--- <3.61t 1.64 0.18 [root@ovirt ~]# In similar way the vmstore storage domain has: - nvme2n1 1Tb gluster_vg_nvme1n1 serial: PHLF8125037R1P0GGN eui.01000000010000005cd2e4e359284f51 dm-1 NVME,INTEL SSDPE2KX010T7 size=932G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 2:0:1:0 nvme2n1 259:2 active undef running [root@ovirt ~]# pvs /dev/mapper/eui.01000000010000005cd2e4e359284f51 PV VG Fmt Attr PSize PFree /dev/mapper/eui.01000000010000005cd2e4e359284f51 gluster_vg_nvme1n1 lvm2 a-- 931.51g 0 [root@ovirt ~]# [root@ovirt ~]# lvs gluster_vg_nvme1n1 LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert gluster_lv_vmstore gluster_vg_nvme1n1 Vwi-aot--- 930.00g gluster_thinpool_gluster_vg_nvme1n1 63.99 gluster_thinpool_gluster_vg_nvme1n1 gluster_vg_nvme1n1 twi-aot--- 921.51g 64.58 1.80 [root@ovirt ~]# I presume the correct way is: - env1 delete and detach vmstore and big2 (without formatting/zeroing) - env2 attach the two disks to the system and then? What should I do at gluster commands level to "import" the already setup gluster bricks/volumes and then at oVirt side to import the corresponding storage domain? BTW: can I import the previous storage domain named "vmstore" giving anothe r name such as vmstore2, not to create conflict with already existing "vmstore" storage domain or the name is hard coded when importing and creating possible conflict? Thanks, Gianluca

In the Logs I see the following: 2020-07-13 17:48:07,292+02 ERROR [org.ovirt.engine.core.dal.dbbroker.BatchProcedureExecutionConnectionCallback] (EE-ManagedThreadFactory-engine-Thread-95) [51091853] Can't execute batch: Batch entry 0 select * from public.insertluns(CAST ('repl_HanaLogs_osd_01' AS varchar),CAST ('DPUtaW-Q5zp-aZos-HriP-5Z0v-hiWO-w7rmwG' AS varchar),CAST ('4TCXZ7-R1l1-xkdU-u0vx-S3n4-JWcE-qksPd1' AS varchar),CAST ('SHUAWEI_XSG1_2102350RMG10HC0000200035' AS varchar),CAST (7 AS int4),CAST ('HUAWEI' AS varchar),CAST ('XSG1' AS varchar),CAST (2548 AS int4),CAST (268435456 AS int8)) as result was aborted: ERROR: duplicate key value violates unique constraint "pk_luns" Detail: Key (lun_id)=(repl_HanaLogs_osd_01) already exists.

Any Idea how to resolve that problem? Thanks a lot -- Arsène Gschwind <arsene.gschwind(a)unibas.ch<mailto:arsene.gschwind@unibas.ch>> Universitaet Basel

ovirt 4.4.1.1 hci and problems with ansible 2.9.10 and/or missing python2
by Gianluca Cecchi 17 Jul '20

17 Jul '20

Hello, today I wanted to test a single host hci install using ovirt-node-ng-installer-4.4.1-2020071311.el8.iso On this same environment 4.4.0 gui wizard worked ok, apart a final problem with cpu flags and final engine boot up, so I wanted to verify if all is ok now, because that problem should have been fixed But I incurred in the same problems recently discussed here: https://lists.ovirt.org/archives/list/users@ovirt.org/message/3AARZD4VBNNHW… The first part failed because of TASK [gluster.infra/roles/backend_setup : Change to Install lvm tools for RHEL systems.] *** fatal: [novirt2st.storage.local]: FAILED! => {"changed": false, "msg": "The Python 2 yum module is needed for this module. If you require Python 3 support use the `dnf` Ansible module instead."} To have the first stage work (now I have to continue with the "Continue to Hosted Engine Deployment" step) I have to modify: - /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/main.yml force to use dnf as package manager. For some reason not automatically detected by the "package" ansible module from - name: Change to Install lvm tools for RHEL systems. package: name: device-mapper-persistent-data state: present when: ansible_os_family == 'RedHat' to - name: Change to Install lvm tools for RHEL systems. package: name: device-mapper-persistent-data state: present use: dnf when: ansible_os_family == 'RedHat' - /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/vdo_create.yml change from yum to package and specify to use dnf from: - name: Install VDO dependencies #maybe use package module? yum: name: "{{ packages }}" register: vdo_deps ... to: - name: Install VDO dependencies #maybe use package module? package: name: "{{ packages }}" use: dnf register: vdo_deps ... So in my opinion a bug has to be opened if not already done. The root cause being or for any reason ansible 2.9.10 that recently updated 2.9.9 or having removed python2 modules from the distribution, that before was for some reason silently used with yum, while not using the expected dnf module with package.... I'm going to test if in the next phase any further modification has to be done. Gianluca

oVirt Node 4.4.1.1 Cockpit Hyperconverged Gluster deploy fails insufficient free space no matter how small the volume is set
by clam2718＠gmail.com 17 Jul '20

17 Jul '20

Hi, Deploying oVirt 4.4.1.1 via Cockpit --> Hosted Engine --> Hyperconverged fails at Gluster deployment: TASK [gluster.infra/roles/backend_setup : Create thick logical volume] ********* failed: [fmov1n3.sn.dtcorp.com] (item={'vgname': 'gluster_vg_nvme0n1', 'lvname': 'gluster_lv_engine', 'size': '100G'}) => {"ansible_index_var": "index", "ansible_loop_var": "item", "changed": false, "err": " Volume group \"gluster_vg_nvme0n1\" has insufficient free space (25599 extents): 25600 required.\n", "index": 0, "item": {"lvname": "gluster_lv_engine", "size": "100G", "vgname": "gluster_vg_nvme0n1"}, "msg": "Creating logical volume 'gluster_lv_engine' failed", "rc": 5} failed: [fmov1n1.sn.dtcorp.com] (item={'vgname': 'gluster_vg_nvme0n1', 'lvname': 'gluster_lv_engine', 'size': '100G'}) => {"ansible_index_var": "index", "ansible_loop_var": "item", "changed": false, "err": " Volume group \"gluster_vg_nvme0n1\" has insufficient free space (25599 extents): 25600 required.\n", "index": 0, "item": {"lvname": "gluster_lv_engine", "size": "100G", "vgname": "gluster_vg_nvme0n1"}, "msg": "Creating logical volume 'gluster_lv_engine' failed", "rc": 5} failed: [fmov1n2.sn.dtcorp.com] (item={'vgname': 'gluster_vg_nvme0n1', 'lvname': 'gluster_lv_engine', 'size': '100G'}) => {"ansible_index_var": "index", "ansible_loop_var": "item", "changed": false, "err": " Volume group \"gluster_vg_nvme0n1\" has insufficient free space (25599 extents): 25600 required.\n", "index": 0, "item": {"lvname": "gluster_lv_engine", "size": "100G", "vgname": "gluster_vg_nvme0n1"}, "msg": "Creating logical volume 'gluster_lv_engine' failed", "rc": 5} Deployment is on 3 count Dell PowerEdge R740xd with 5 count 1.6TB NVMe drives per host. Deployment is only to three as JBOD, 1 drive per node per volume (engine, data, vmstore) utilizing VDO. Thus, deploying even a 100G volume to 1.6TB drive fails with "insufficient free space" error. I suspect this might have to do with the Ansible playbook deploying Gluster mishandling the logical volume creation due to the rounding error as described here: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/ht… If I can provide any additional information, logs, etc. please ask. Also, if anyone has experience/suggestions with Gluster config for hyperconverged setup on NVMe drives I would greatly appreciate any pearls of wisdom. Thank you so very much for any assistance!

Parent checkpoint ID does not match the actual leaf checkpoint

Hello, Thanks to previous answers, I was able to make backups. Unfortunately, we had some infrastructure issues and after the host reboots new problems appeared. I am not able to do any backup using the commands that worked yesterday. I looked through the logs and there is something like this: 2020-07-17 15:06:30,644+02 ERROR [org.ovirt.engine.core.bll.StartVmBackupCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-54) [944a1447-4ea5-4a1c-b971-0bc612b6e45e] Failed to execute VM backup operation 'StartVmBackup': {}: org.ovirt.engine.core.common.errors.EngineException: EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed to StartVmBackupVDS, error = Checkpoint Error: {'parent_checkpoint_id': None, 'leaf_checkpoint_id': 'cd078706-84c0-4370-a6ec-654ccd6a21aa', 'vm_id': '116aa6eb-31a1-43db-9b1e-ad6e32fb9260', 'reason': 'Parent checkpoint ID does not match the actual leaf checkpoint'}, code = 1610 (Failed with error unexpected and code 16) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.VdsHandler.handleVdsResult(VdsHandler.java:114) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.VDSBrokerFrontendImpl.runVdsCommand(VDSBrokerFrontendImpl.java:33) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.CommandBase.runVdsCommand(CommandBase.java:2114) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.StartVmBackupCommand.performVmBackupOperation(StartVmBackupCommand.java:368) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.StartVmBackupCommand.runVmBackup(StartVmBackupCommand.java:225) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.StartVmBackupCommand.performNextOperation(StartVmBackupCommand.java:199) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.SerialChildCommandsExecutionCallback.childCommandsExecutionEnded(SerialChildCommandsExecutionCallback.java:32) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.ChildCommandsCallbackBase.doPolling(ChildCommandsCallbackBase.java:80) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.tasks.CommandCallbacksPoller.invokeCallbackMethodsImpl(CommandCallbacksPoller.java:175) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.tasks.CommandCallbacksPoller.invokeCallbackMethods(CommandCallbacksPoller.java:109) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.runAndReset(FutureTask.java:305) at org.glassfish.javax.enterprise.concurrent//org.glassfish.enterprise.concurrent.internal.ManagedScheduledThreadPoolExecutor$ManagedScheduledFutureTask.access$201(ManagedScheduledThreadPoolExecutor.java:383) at org.glassfish.javax.enterprise.concurrent//org.glassfish.enterprise.concurrent.internal.ManagedScheduledThreadPoolExecutor$ManagedScheduledFutureTask.run(ManagedScheduledThreadPoolExecutor.java:534) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:834) at org.glassfish.javax.enterprise.concurrent//org.glassfish.enterprise.concurrent.ManagedThreadFactoryImpl$ManagedThread.run(ManagedThreadFactoryImpl.java:250) And the last error is: 2020-07-17 15:13:45,835+02 ERROR [org.ovirt.engine.core.bll.StartVmBackupCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-14) [f553c1f2-1c99-4118-9365-ba6b862da936] Failed to execute VM backup operation 'GetVmBackupInfo': {}: org.ovirt.engine.core.common.errors.EngineException: EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed to GetVmBackupInfoVDS, error = No such backup Error: {'vm_id': '116aa6eb-31a1-43db-9b1e-ad6e32fb9260', 'backup_id': 'bf1c26f7-c3e5-437c-bb5a-255b8c1b3b73', 'reason': 'VM backup not exists: Domain backup job id not found: no domain backup job present'}, code = 1601 (Failed with error unexpected and code 16) (these errors are from full backup) Like I said this is very strange because everything was working correctly.

Engine deployment fails with engine booting to grub rescue
by Andy 17 Jul '20

17 Jul '20

After working through some DNS problems I was able to install oVirt 4.4.1.1 and progress the engine deployment stops within the ansible scripts. The system deploys the gluster domain, creates the engine, starts the engine, however it will never fully boot and complete the deployment. Bringing up the console of the engine sets it into rescue mode. I have attempted to set the appropriate variables in grub rescue set root=(hd0,msdos1) set prefix=(hd0,msdos1)/boot/grub insmod normal And this will not boot the engine. Is there a procedure to mount a CENTOS 8 rescue CD/ISO to troubleshoot this or is there a specific fix published for this problem? The specific error I am seeing in the Engine Console is "attempt to read outside of HD0. I upgraded the ovirt engine appliance package to ovirt-engine-appliance-4.4-20200716090128.1.el8.x86_64 which produces the same result. I have gotten this error deploying on both my Intel and AMD based servers. any help is appreciated. thanks Andy

ovirt-node-ng-image-update 4.4.1 to 4.4.1.1
by David M. Hornsby 16 Jul '20

16 Jul '20

All, I applied the recent update 4.4.1 -> 4.4.1.1 to a host in a cluster and it failed. After reboot it was hund at the emergency console. I reinstalled 4.4.1 fresh on the host. Prior to adding it back to the cluster I applied the same update with the same result. Is this just a bad update or is the post install script bad. Thanks, David.
