Of course, this should work. The only point is that once 4.3.6 is released, it's not that easy to install 4.3.5, because yum generally tries to install the latest versions of stuff - and in theory, there might be issues with installing stuff from 4.3.6 repo with a 4.3.5 engine, so if you want an exact replicate of a 4.3.5 engine, you have to check all relevant packages, not just the engine. > > Regards, > Paul S. > ________________________________ > From: Yedidyah Bar David <didi(a)redhat.com> > Sent: 11 November 2019 10:19 > To: Staniforth, Paul <P.Staniforth(a)leedsbeckett.ac.uk> > Cc: wangyu13476969128(a)126.com <wangyu13476969128(a)126.com>; users <users(a)ovirt.org> > Subject: Re: [ovirt-users] Re: After importing the ovirt-engine 4.3.5 backup file into ovirt-engine 4.3.6, will the information of the ovirt-engine 4.3.6 management interface be the same as ovirt-engine 4.3.5? > > On Mon, Nov 11, 2019 at 12:12 PM Staniforth, Paul > <P.Staniforth(a)leedsbeckett.ac.uk> wrote: > > > > I haven't tried it but doesn't engine-setup --offline stop it upgrading minor releases. > > It prevents only the packager component. > > If you already have 4.3.6 installed, which was the original question, > then engine-setup will still update the database schema.

It prevents only the packager component. If you already have 4.3.6 installed, which was the original question, then engine-setup will still update the database schema. And if it didn't, the 4.3.6 engine might fail working correctly with a 3.4.5.5 database. In particular: The documentation for engine-backup always stated that you must run engine-setup immediately after restore. But at some points in time, and under certain conditions, this was actually optional. You could have done a restore, and immediately start the engine, and it would have worked. But this isn't the case if your restored db is older than the installed engine. Then, you must run engine-setup before starting the engine.

Supporting larger than 8TiB Lun's iSCSI RHV/oVirt
by Green, Jacob Allen /C 11 Nov '19

11 Nov '19

I have a question regarding the information in the following screenshot. According to https://access.redhat.com/articles/906543 there is an 8TiB limit I assume this is per LUN? Also if I want to go past 8TiB per LUN is there some configuration I need to edit somewhere? And is there a problem with going past 8TiB per LUN? I think it more manageable to simply increase LUN sizes if you have the storage, instead of adding additional LUN’s to your storage domain, however I may not fully understand the problems with increasing LUN sizes. Thank you. [cid:image001.png@01D5948E.D0101740] Jacob.

After importing the ovirt-engine 4.3.5 backup file into ovirt-engine 4.3.6, will the information of the ovirt-engine 4.3.6 management interface be the same as ovirt-engine 4.3.5?
by wangyu13476969128＠126.com 11 Nov '19

11 Nov '19

The current version of ovirt-engine in production environment is 4.3.5.5. In order to prevent the ovirt-engine machine from being down, the management interface cannot be used, according to the relevant link: https://ovirt.org/documentation/admin-guide/chap-Backups_and_Migration.html I backed it up using the command: engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name I have prepared another machine as a spare machine. Once the ovirt-engine is down in the production environment, the standby machine can be UP and the standby machine can manage the ovirt-nodes. According to the relevant links: https://ovirt.org/documentation/install-guide/chap-Installing_oVirt.html The ovirt-engine is installed on the standby machine. After I have executed these three commands: 1. yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 2. yum update 3. yum install ovirt-engine I found that the ovirt-engine version of the standby machine is 4.3.6 So my question is: 1. The ovirt-engine version of the standby machine is 4.3.6, and the production environment ovirt-engine version is 4.3.5.5, which command is used on the production environment ovirt-engine machine: engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name Files obtained after using the backup command on the ovirt-engine in the production environment are restored using these two files under the standby computer. Will the information on the ovirt-engine management interface of the standby computer be consistent with the ovirt-engine of the production environment (eg data center, host, virtual machine, etc.)? 2. Can the ovirt-engine of the standby machine be installed with version 4.3.5.5? How do I need to modify the following three commands to get the backup machine to install the version 4.3.5.5? 1. yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 2. yum update 3. yum install ovirt-engine

Long post about gluster issue after 6.5 to 6.6 upgrade and recovery steps
by Strahil Nikolov 10 Nov '19

10 Nov '19

Hello Colleagues, I want to share my experience and especially how I have recovered after a situation where gluster refuses to heal several files of my oVirt Lab. Most probably the situation was caused by the fact that I didn't check if all files were healed before I started the upgrade on the next node , which in a 'replica 2 arbiter1' setup has caused multiple files missing/conflicting and heal fails to happen. Background:1. I have powered off my HostedEngine VM and made a snapshot of the gluster volume2. Started the update , but without screen - I messed it up and decided to revert from the snapshot3. Powered off the volume , restored from snapshot and then started (and again snapshoted the volume)4. Upgrade of the HostedEngine was successfull5. Upgraded the arbiter (ovirt3)6. I forgot to check the heal status on the arbiter and upgraded ovirt1/gluster1 (which maybe was the reason for the issue)7. After gluster1 was healed I saw that some files are left for healing , but expected it will finish till ovirt2/gluster2 is patched8. Sadly my assumption was not right and after the reboot of ovirt2/gluster2 I noticed that some files never heal. Symptoms:2 files per volume never heal (used 'full' mode) even after I 'stat'-ed every file/dir in the volume.Ovirt Dashboard reported multiple errors (50+) that it cannot update the OVF metadata for volume/VM. Here are my notes while I was recovering from the situation. As this is my LAB, I shutdown all VMs (including the HostedEngine) as downtime was not an issue: Heals never complete: # gluster volume heal data_fast4 info Brick gluster1:/gluster_bricks/data_fast4/data_fast4 Status: Connected Number of entries: 0 Brick gluster2:/gluster_bricks/data_fast4/data_fast4 <gfid:d21a6512-eaf6-4859-90cf-eeef2cc0cab8> <gfid:95bc2cd2-8a1e-464e-a384-6b128780d370> Status: Connected Number of entries: 2 Brick ovirt3:/gluster_bricks/data_fast4/data_fast4 <gfid:d21a6512-eaf6-4859-90cf-eeef2cc0cab8> <gfid:95bc2cd2-8a1e-464e-a384-6b128780d370> Status: Connected Number of entries: 2 Mount to get the gfid to path relationship: mount -t glusterfs -o aux-gfid-mount gluster1:/data_fast4 /mnt #

oVirt orb python3/fedora 31 support
by Baptiste Agasse 08 Nov '19

08 Nov '19

Hi all, I was an happy user of oVirt orb on my laptop to do some testing (New features, foreman integration tests , ansible modules/playbooks/roles tests...) and it worked realy well, thanks guys ! Last week I've upgraded my laptop to fedora 31 and I have to uninstall ovirt-orb/lago related stuff to be able upgrade to this fedora version (related to python2 dependencies packages missing on fedora 31). Is there any planned python3/fedora 31 support for ovirt-orb/lago-ovirt/lago ? If not there is any simple replacement solution to spin up a light ovirt env to this kind of tests ? Have a nice day.

Second attempt 😊 From: "Vrgotic, Marko" <M.Vrgotic(a)activevideo.com> Date: Monday, 4 November 2019 at 14:01 To: "users(a)ovirt.org" <users(a)ovirt.org> Subject: oVirt and Netapp question Dear oVirt, Few months ago our production environment oVirt with main Shared storage via NFS Netapp is live. We have been deploying VMs with thin provisioned HDD 40GB based template, CentOS 7. The Netapp NFS v4 storage volume is 7TB in size, also Thin Provisioned. First attached screenshot shows the space allocation of the production volume from Netapp side. Is there anyone in oVirt community who would be able to tell me the meaning of the 5.31 TB Over Provisioned Space? [A screenshot of a cell phone Description automatically generated] Second attached is the info of the production volume from oVirt side: [A screenshot of a social media post Description automatically generated] What I want to understand is the way how is oVirt reading the volume usage and Netapp and where is the difference. Is the Over Allocated Space something that is just logically used/reserved and will be intelligently re-allocated/re-used as the actual Data Space Used grows or am I looking at oVIrt actually hitting Critical Space Action Blocker and will have to resize the volume? If there is anyone from Netapp or with good Netapp experience that is able to help understanding the data above better, thank you in advance? Kindly awaiting your reply. ----- kind regards/met vrindelijke groet Marko Vrgotic ActiveVideo

Users and VM permissions matrix
by Colin Coe 08 Nov '19

08 Nov '19

Hi all I've been tasked with creating a matrix of users/groups and VMs so we can easily see who has access to what (via SPCIE console). Google has given me a couple of hints but I can get it over the line. --- users_service = connection.system_service().users_service() users = users_service.list() for user in users: username = user.user_name.split('@')[0] # Follow the link to the permissions of the user: perms = connection.follow_link(user.permissions) for perm in perms: if perm.vm: print(username) permissions_service = connection.system_service().permissions_service() print(perm.vm.id) --- The problem is with permissions, the output from above is: --- user1 1b645daf-de26-4f33-9e3b-6a12eadd4618 user2 9c79e763-f78d-4bf9-b8ca-20fe197fd80c user3 f9d00b30-8003-41c3-95a1-10e0c452fa63 user4 1bbadf96-ef95-4ece-b5f3-1fa112aa3571 user5 e9085627-324e-48d3-bc04-52ff7798ddd0 --- I can't work out how to get the actual permissions rather that the ID. Any ideas? Thanks

Quick generic Questions
by Christian Reiss 07 Nov '19

07 Nov '19

Hey folks, I am looking at setting up a hyperconverged cluster with 3 nodes (and oVirt 4.3). Before setting up I have some generic questions that I would love to get hints or even an answer on. First off, the Servers are outfittet with 24 (SSD) drives each in a HW-RAID. Due to wear-leveling and speed I am looking at RAID10. So I would end up with one giant sda device. a) Partitioning Using oVirt node installer which will use the full size of /dev/sda is this still the right solution to Hyperconverged given the gluster issue? If I understood it correctly gluster is using empty drives or partitions so a fully utilized drive is of no use here. Does oVirt node installer have a hyperconverged/ gluster mode? b) Storage Location In this 3 node cluster, creating a VM on node01 will the data for node01 always end up in the local node01 server? c) Starting VMs Can a VM be migrated or launched from node03 if the data resides on node01 and node02 (copies 2 with arbiter). d) Efficiency / High IO Load If node01 has high IO Load would additional data be loaded from the other node which has the copy to even the load? I am aware Virtuozzo does this. e) Storage Network dies What would happen with node01, node02 and node03 are operational but only the storage network dies (frontend is still alive as are the nodes). f) external isci/ FreeNAS We have a FreeNAS system with tons of space and fast network connectivity. Can oVirt handle storage import like remote iscsi target and run VMs on the ovirt nodes but store data there? Thank you for your time to clear this up. I have found many approaches out there that either are old (oVirt 3) or even contradict themselves (talk about RAID level...)

CPU Pinning topology
by Fabrice Bacchella 07 Nov '19

07 Nov '19

I'm trying to understand the field "CPU Pinning topology" in the "Ressource Allocation" tab, that looks it needed by High Performance VM. I have this hardware: # lscpu Architecture: x86_64 CPU(s): 48 On-line CPU(s) list: 0-47 Thread(s) per core: 2 Core(s) per socket: 12 Socket(s): 2 NUMA node(s): 2 And I want to run a 22 vCPU vm on it, so no SMT, and 11 vCPU mapped to each socket. The only explanation I found about this field content was here: https://rhv.bradmin.org/ovirt-engine/docs/Virtual_Machine_Management_Guide/… and I can wrap my head around it. Do I need to given explicit mapping for all the 22 vCPU ? And dig in lscpu -e or numactl -H to find how each pCPU is identified ?

Can ovirt-node support multiple network cards ？

Can ovirt-node support multiple network cards ？ I download ovirt-node-ng-installer-4.3.5-2019073010.el7.iso from ovirt site. And install on a Dell R730 Server. The version of ovirt-engine is 4.3.5.5. I found that the logic network ovirtmgmt can only point to one network card interface. Can ovirt-node support multiple network cards ？ If yes , please tell me the method.

How to pass parameters between VDSM Hooks domxml in single run
by Vrgotic, Marko 06 Nov '19

06 Nov '19

Dear oVIrt, A while ago we discussed on ways to change/update content of parameters of domxml in certain action. As I mentioned before, we have added the VDSMHook 60_nsupdate which removes the DNS record entries when a VM is destroyed: … domxml = hooking.read_domxml() name = domxml.getElementsByTagName('name')[0] name = " ".join(name.nodeValue for name in name.childNodes if name.nodeType == name.TEXT_NODE) nsupdate_commands = """server {server_ip} update delete {vm_name}.example.com a update delete {vm_name}. example.com aaaa update delete {vm_name}. example.com txt send """.format(server_ip="172.16.1.10", vm_name=name) … The goal: However, we did not want to execute remove dns records when VM is only migrated. Since its considered a “destroy” action we took following approach. * In state “before_vm_migrate_source add hook which will write flag “is_migration” to domxml * Once VM is scheduled for migration, this hook should add the flag “is_migration” to domxml * Once 60_nsupdate is triggered, it will check for the flag and if there, skip executing dns record action, but only remove the flag “is_migration” from domxml of the VM … domxml = hooking.read_domxml() migration = domxml.createElement("is_migration") domxml.getElementsByTagName("domain")[0].appendChild(migration) logging.info("domxml_updated {}".format(domxml.toprettyxml())) hooking.write_domxml(domxml) … When executing first time, we observed that flag “ <name>hookiesvm</name> <uuid>fcfa66cb-b251-43a3-8e2b-f33b3024a749</uuid> <metadata xmlns:ns0="http://ovirt.org/vm/tune/1.0" xmlns:ns1="http://ovirt.org/vm/1.0"> <ns0:qos/> <ovirt-vm:vm xmlns:ovirt-vm="http://ovirt.org/vm/1.0"> <ovirt-vm:clusterVersion>4.3</ovirt-vm:clusterVersion> <ovirt-vm:destroy_on_reboot type="bool">False</ovirt-vm:destroy_on_reboot> <ovirt-vm:launchPaused>false</ovirt-vm:launchPaused> <ovirt-vm:memGuaranteedSize type="int">1024</ovirt-vm:memGuaranteedSize> <ovirt-vm:minGuaranteedMemoryMb type="int">1024</ovirt-vm:minGuaranteedMemoryMb> ...skipping... <address bus="0x00" domain="0x0000" function="0x0" slot="0x09" type="pci"/> </rng> </devices> <seclabel model="selinux" relabel="yes" type="dynamic"> <label>system_u:system_r:svirt_t:s0:c169,c575</label> <imagelabel>system_u:object_r:svirt_image_t:s0:c169,c575</imagelabel> </seclabel> <seclabel model="dac" relabel="yes" type="dynamic"> <label>+107:+107</label> <imagelabel>+107:+107</imagelabel> </seclabel> <is_migration/> </domain> is added to domxml, but was present once 60_nsupdate hook was executed. The question: How do we make sure that, when domxml is updated, that the update is visible/usable by following hook, in single run? How to pass these changes between hooks? Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic

[feedback needed] oVirt master test
by Sandro Bonazzola 05 Nov '19

05 Nov '19

Hi, as part of the 4.4 development we'd like to ask for testing current master. In order to ease the test, you can take: oVirt Node: https://resources.ovirt.org/pub/ovirt-master-snapshot/iso/ovirt-node-ng-ins… when this link won't be available anymore due to nightly build rotation you can take the latest from https://resources.ovirt.org/pub/ovirt-master-snapshot/iso/ovirt-node-ng-ins… oVirt appliance: https://resources.ovirt.org/pub/ovirt-master-snapshot/rpm/el8/x86_64/ovirt-… as per oVirt Node, you can take the latest from https://resources.ovirt.org/pub/ovirt-master-snapshot/rpm/el8/x86_64/ if above link doesn't work. The above 2 builds have been tested on a single host nested VM system with 70Gb disk, 8Gb of RAM and 4 cores for the node. Both oVirt Node and oVirt Engine appliance installation succeeded on 80GB NFS external storage with static IP addressing. We have a known issue on booting with more than 1 NIC that will be addressed soon, so please use a single NIC in your tests for now. Looking forward for your feedback, thanks. -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/>*Red Hat respects your work life balance.
