How to assign a server disk and nic profile via REST API?
by ovirt.org＠nevim.eu 02 May '21

Hello to everybody, for about an hour I have stuck my nose in the ovirt and rhev documentation, but I still can't understand how to use the REST API to change the disk profile and nothing the server profile. Ideally, how to set it for them when setting up a VM. Thank you so much for the advice.

Slow VM replication
by David Johnson 30 Apr '21

30 Apr '21

Hi everyone, When cloning a VM, I discovered that the time to close appears excessive based on the underlying platform I am using. It appears that the clone operation is not making efficient use of the network. I have seen up to 4 GBits sustained throughput by applications on VM's on the cluster. Is there a configuration I might be missing? *System specifics:* Backing store: NFS on TrueNAS running zRaid 3 on 11 spinning disks Ovirt Controller: I7 desktop General network: 1 GBit Ethernet Ovirt Host: Intel(R) Xeon(R) Silver 4216 CPU @ 2.10GHz, 2x32 cores, 256 GB RAM Data Network: 10 GBit 10GBase-Twinax, dedicated to this Host and the TrueNAS *Operation:* Copying the 60GB partition, the copy operation never exceeds 40 megabytes per second (less than 0.5 GBit), even though the dedicated 10 Gigabit data network is not otherwise busy.

Hi, I haven't found a global option to set this. You'll have to do it vm after vm, which isn't a bad thing in my opinion as you'll have to reboot every vm after enabling HA anyways. For new VMs depending on your workflow I'd create a template or an instance type with HA enabled. You can also enable HA in the preset instance types via "Administration" > "Configure" > "Instance Types". Keep in mind that you will have to enable advanced options to see the High Avalibitity tab. Best regards, Tivon

Unable to migrate Engine to another HE Host
by Marko Vrgotic 30 Apr '21

30 Apr '21

Dear oVirt, I have already reached out twice regarding the issues that occurred, due to power outage, but noticed only when upgrading engine to latest 4.3. version. I am unable to redeploy engine on Host2, the hosted-engine file stays empty and VDSM on Hosts1 and 3 is reporting, even though I cleared the metadata for the Host2, on Host 1 and Host3: 2021-04-30 05:57:58,454-0700 ERROR (jsonrpc/7) [ovirt_hosted_engine_ha.client.client.HAClient] Malformed metadata for host 2: received 0 of 512 expected bytes (client:137) Today I tried to migrate HE from Host 3 to Host 1 and it fails each time with following message: On Engine: 2021-04-30 12:57:56,961Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-1233892) [] EVENT_ID: VM_MIGRATION_TO_SERVER_FAILED(120), Migration failed (VM: HostedEngine, Source: ovirt-sj-03.ictv.com, Destination: ovirt-sj-01.ictv.com) On source Host: 2021-04-30 05:57:56,705-0700 ERROR (migsrc/66b6d489) [virt.vm] (vmId='66b6d489-ceb8-486a-951a-355e21f13627') Failed to migrate (migration:450) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 431, in _regular_run time.time(), migrationParams, machineParams File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 505, in _startUnderlyingMigration self._perform_with_conv_schedule(duri, muri) File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 591, in _perform_with_conv_schedule self._perform_migration(duri, muri) File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 525, in _perform_migration self._migration_flags) File "/usr/lib/python2.7/site-packages/vdsm/virt/virdomain.py", line 100, in f ret = attr(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/function.py", line 94, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1781, in migrateToURI3 if ret == -1: raise libvirtError ('virDomainMigrateToURI3() failed', dom=self) libvirtError: operation aborted: migration out job: canceled by client I know that this version is end of life – but I would very much appreciate if someone could help me asses if this means corruption in DB or the overall damage, simply to know how to plan further actions. My impression was that I still had to functional HE Hosts in the pool, but after seeing migration failure, it’s pretty much down to single host. This is production system, so I cannot just move on to upgrading/deploying to 4.4. Additionally – : * Is the effect of the engine-cleanup on HE Host local or it affects all HE Hosts? Could that help bringing the Host back to state so that HE can be re-deployed? * What is the effect or reinitialize-lockspace? Kindly awaiting your reply.

how to override host in console.vv
by Enrico Becchetti 30 Apr '21

30 Apr '21

Hi all, I use ovirt 4.3.10 with an engine running in a standalone virtual machine. The operating system of this engine and the hypervisors is CentOS 7. In the initial setup I chose a name for the engine, ovirt.local, then I added a second public IP address named ovirt.mydomain in order to allow the user portal also from the Internet. Now here's my problem. Users are able to connect to the VM portal but they cannot access the console of their virtual machines. Checking the console.vv file I noticed that there are two parts, the first [virt-viewer] which contains the hypervisor on which the virtual machine runs, and the second in this configuration [ovirt] inside ovirt I've got "host = ovirt.local: 443". Now I would like to change the value of the "host" parameter with the FQDN. Can you tell me how I can set an override of this variable ? Thanks a lot.

Re: Unable to provide network acces to second cluster in DC
by Miguel Garcia 29 Apr '21

Browsing at the path above I see prodvlan and havlan listed and manage network settings is the same as Public1. Compute > Clusters > Public2 > Logical Network > Manage Networks The problem is that when I try to create a vm for cluster Public2 on the nic sections no nic profile are listed, it remains <empty> option only.

29 Apr '21

oVirt 4.4.6 Sixth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.6 Sixth Release Candidate for testing, as of April 29th, 2021. This update is the sixth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.6 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.6 (redeploy in case of already being on 4.4.6). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot.

how to enable HA for all vms and entire cluster at global settings
by dhanaraj.ramesh＠yahoo.com 29 Apr '21

29 Apr '21

Hi Team instead of enabling HA for each vm one by one, I want to enable HA for all vms that is already running in the cluster and also for the future vms that going to be installed. I already did configure HA reservation at the cluster level, any other settings or commands I should configure? how I can achieve the above

Unable to provide network acces to second cluster in DC
by Miguel Garcia 28 Apr '21

28 Apr '21

I have created the following DC and cluster structure in my ovirt server - Data Center Public - - cluster-public1 - - cluster-public2 Also created a couple Logical Network for DC-Public - - prodvlan - - havlan And added 4 host (two for each cluster because processor type) and each host has ports added to both logical networks (besides ovirtmgmt) When I create a new vm in cluster public1 and add nics I'm able to list prodvlan and havlan but when I try to create the vm for cluster public2 no logical networks are listed. Any idea how to get logical networks listed for cluster public2? Thanks in advance

Restoring hosted engine from backup fails on new FC storage domain creation
by Juhani Rautiainen 28 Apr '21

28 Apr '21

Hi! I started the upgrade from 4.3->4.4. Now I'm stuck as restoring the backup fails to create the correct storage domain for Hosted Engine. How can I create one? Error from ansible task is: [ ERROR ] ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Domain format is different from master storage domain format]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Domain format is different from master storage domain format]\". HTTP response code is 400."} And from UI I can see that what has been created is a data domain. Not data (master) domain as old one was. Now I'm stuck here. This is a fibre channel system where I'm trying to do this if it is relevant. What I could find from the logs is this: 2021-04-27 09:36:06,925+0300 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:105 storage_domain_details: {'changed': False, 'ovirt_storage_domains': [{'href': '/ovirt-engine/api/storagedomains/dd52022b-7616-47f6-9534-6f1a4084fdf4', 'comment': '', 'description': '', 'id': 'dd52022b-7616-47f6-9534-6f1a4084fdf4', 'name': 'hosted_storage', 'available': 531502202880, 'backup': False, 'block_size': 512, 'committed': 0, 'critical_space_action_blocker': 5, 'discard_after_delete': True, 'disk_profiles': [], 'disk_snapshots': [], 'disks': [], 'external_status': 'ok', 'master': False, 'permissions': [], 'status': 'unattached', 'storage': {'type': 'fcp', 'volume_group': {'id': 'HRLDCn-p7X2-5X2O-vm4h-1Wb9-wAMu-WkIwit', 'logical_units': [{'discard_max_size': 268435456, 'discard_zeroes_data': False, 'id': '36000d31005b4f6000000000000000029', 'lun_mapping': 3, 'paths': 0, 'product_id': 'Compellent Vol', 'serial': 'SCOMPELNTCompellent_Vol_0005b4f6-00000029', 'size': 536870912000, 'storage_domain_id': 'dd52022b-7616-47f6-9534-6f1a4084fdf4', 'vendor_id': 'COMPELNT', 'volume_group_id': 'HRLDCn-p7X2-5X2O-vm4h-1Wb9-wAMu-WkIwit'}]}}, 'storage_connections': [], 'storage_format': 'v5', 'supports_discard': True, 'supports_discard_zeroes_data': False, 'templates': [], 'type': 'data', 'used': 4294967296, 'vms': [], 'warning_low_space_indicator': 10, 'wipe_after_delete': False}], 'failed': False} 'master': False? I'm not sure if this creation or check. I tried this opration twice. I removed the new hosted_storage and remove also old hosted_engine domain on second try to make sure that it doesn't prevent creation of another master. No luck with that. Thanks, Juhani
