n00b Requesting Some Advice
by matthew＠peregrineit.net 22 Apr '21

22 Apr '21

Hi All, I need some "best practice" advice. We have a Ceph Storage Cluster (Octopus moving to Pacific) which we'd like to use with our new oVirt Cluster (all on CentOS 8 boxes). What I'd like to know is what is the "best" (ie recommended / best practice) way of doing this - via iSCSI, CFS, 'raw' RBD blocks, some other way I haven't read about yet, etc? I realise 'best' is a subjective term, but what I tend to do is do 'manual' installs so that I both actually understand what is happening (ie how things fit together - I pull apart and rebuild mechanical clocks and watches for the same reason) and also so I can '"Puppet-ise" the results for future use. This means that I am *not* necessarily looking for "quick and dirty" or "quick and easy" (ie, I have no trouble using the CLI and 'vim-ing' conf files as required) but I do want a solid, "best-practice" system when I'm done. So, can some please help? And also, would you mind pointing me towards the relevant documentation for the answer(s) supplied (yes, I *always* RTFM :-) ). Thanks in advance Dulux-Oz

[ANN] oVirt 4.4.6 Fifth Release Candidate is now available for testing
by Lev Veyde 22 Apr '21

22 Apr '21

oVirt 4.4.6 Fifth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.6 Fifth Release Candidate for testing, as of April 22nd, 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. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>.

Ansible ovirt.ovirt_vm nics
by Matthew.Stier＠fujitsu.com 22 Apr '21

22 Apr '21

The 'nics' section of ovirt_vm is vague and with nearly no examples. My playbook is based upon https://blogs.oracle.com/scoter/ansible-with-oracle-linux-virtualization-ma… I've made several modifications, (more default) and added a few lines, which I believe is supposed to assign vnic profiles to the primary vnic (nic1), based upon the definition of 'vm_nic1_profile' defined in an included 'ini' file. (the profile defaulting to blank if it is not defined in the ini file.) It isn't doing its job. nics: - name: "nic1" profile_name: "{{ hostvars[item]['vm_nic1_profile'] | default('') }}" The playbook runs without complaint. If I run it with option '-vvv' part of the output lists the variables, but the 'nics' variable is an empty list (nics[]) Any hints on what I'm doing wrong? I've checked the forum, but it tends to strip leading spaces, which is bad for indent sensitive code.

Moving templates and their thin based VMs
by Gianluca Cecchi 21 Apr '21

21 Apr '21

Hello, I had to free up and reformat a storage domain where I had some templates and many VMs. I was able to move to other existing storage domains disks of VMs created with "Clone" Storage Allocation But some of these VMs had disk with storage allocation of type "Thin" on their related template. So I was both unable to move these templates and VMs disks... I was able to export as OVA the templates and then import again them (with another name "_Copy") on to another storage domain.... then remove VMs and templates and rename templates' names... Are there any chances to better solve these kind of problems if one has to decommission a storage domain? Only export of all VMs and related templates? Is there a way to "consolidate" the disks of an existing "Thin" based storage allocation to Clone? Possibly I can clone the VM? Thanks in advance, Gianluca

oVirt Node's Future Regarding CentOS Stream
by eshwayri＠gmail.com 21 Apr '21

21 Apr '21

So I just finished migrating my 4.3 engine to 4.4 on a brand new RHvEL8 install; next step is to upgrade the hosts. When I first started with oVirt I used my own CentOS installs, but quickly decided that it made no sense for my use case. Now I am looking at upgrading from 4.3 to 4.4 and asking myself the same question. Up to now oVirt node has been using the same exact OS I would have used +/- a few extra packages, but with the traditional CentOS going away it really depends on what the new oVirt nodes are going to be based on. I have a feeling the answer to that question is CentOS Stream, which I don't feel comfortable with for this task. While I am sure the developers will test the combination before releasing a new node, they are still only testing whatever specific hardware combination they have. There could be numerous weird bugs that will only show up in certain situations. If Stream was as stable as an EL release, there wouldn't be EL releases. I also appreciate the fa ct that oVirt is itself a work in progress, but the stable branch is considerably more like an EL release than a stream. Anyway, back to the point. Just want to confirm the future for node is stream before I go wasting time building my own EL8 hosts.

I've just given it a try: works just fine with me. But I did notice, that I chose virtio-scsi when I created the disk, don't now if that makes any difference, but as an old-timer, I still got "SCSI" ingrained as "better than ATA". Chose FreeBSD 9.2 x64 as OS type while creating the VM (nothing closer appears in the selection box), again don't know if there are better choices. iperf3 shows slightly lower performance than a typical Linux guest, still rather close to 10Gbit/s on my network from the FreeBSD13 guest to a host "next-door", around 40Gbit/s VM to host. Verfied usage of vtnet0/VirtIO NIC and vtscsi0/VirtIO SCSI via dmesg.

Is it possible to upgrade 3 node HCI from 4.3 to 4.4?
by Jayme 20 Apr '21

20 Apr '21

I have a fairly stock three node HCI setup running oVirt 4.3.9. The hosts are oVirt node. I'm using GlusterFS storage for the self hosted engine and for some VMs. I also have some other VMs running from an external NFS storage domain. Is it possible for me to upgrade this environment to 4.4 while keeping some of the VMs on GlusterFS storage domains running? Does the upgrade require an additional physical host? I'm reading through the upgrade guide and it's not very clear to me how the engine is reinstalled on CentOS8. Do you need a 4th host, or do you take one of the three existing hosts down, wipe it and install ovirt node 4.4? Would it be easier for me to just move all VMs to my NFS storage domain, wipe all hosts and deploy a brand new 4.4 HCI cluster then import the NFS storage domain? Will the 4.3 VMs on the NFS storage domain import/run properly into the new 4.4 deployment or are there any other considerations?

intel_iommu=on kvm-intel.nested=1 deactivates rp_filter kernel option
by Nathanaël Blanchet 20 Apr '21

20 Apr '21

Hello, I have two kind of hosts: * some with default ovirt node 4.4 kernel settings * some with custom kernel settings including intel_iommu=on kvm-intel.nested=1 I can't open vm console from the second category host when binding from a different vlan because the host is unreacheable But if I set sysctl -w net.ipv4.conf.all.rp_filter=2, I can bind the host and open a vm console. I didn't test if this behaviour is because of Hostdev Passthrough & SR-IOV or Nested Virtualization. Is it an expected behaviour or a bug? -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Two selfhosted engines
by wilrikvdvliert＠hotmail.com 20 Apr '21

20 Apr '21

Dear forum, If I understand correctly, I need shared storage for the self-hosted engine to make it highly available. But is it possible to create 2 self-hosted engines on 2 hosts and make it high available this way? Kind regard

ova import
by eevans＠digitaldatatechs.com 20 Apr '21

20 Apr '21

I am running Ovirt 4.3 and exported machines as ova which includes disks. When I re import them. the disks are thin provisioned and the vm will not boot. Any idea how to get the import to preallocate disks? I have vms that will not boot. It states no bootable disk is available. It seems the virt2vm isn't working correctly. ANy help would be appreciated. Eric

[Help] The engine is not stable on HostedEngine with GlusterFS Herperverged deployment
by mengz.you＠outlook.com 20 Apr '21

20 Apr '21

Hi, I deployed a oVirt (4.3.10) cluster with HostedEngine and GlusterFS volumes (engine, vmstore, data), the glusterfs cluster on node1/node2/node3, and the engine vm can be running on those 3 nodes. Then I added a 4th nodes into cluster. But, when I operates on Eninge Web Portal, it's always reports 503 error, then I checked `hsoted-engine --vm-status`, see below: ``` [root@vhost1 ~]# hosted-engine –vm-status –== Host vhost1.yhmk.lan (id: 1) status ==– conf_on_shared_storage : True Status up-to-date : True Hostname : vhost1.<span style=”background-color: rgb(255, 255, 255); color: rgb(51, 51, 51);”>alatest</span>.lan Host ID : 1 Engine status : {“reason”: “bad vm status”, “health”: “bad”, “vm”: “down_unexpected”, “detail”: “Down”} Score : 0 stopped : False Local maintenance : False crc32 : 1f25baff local_conf_timestamp : 1253650 Host timestamp : 1253649 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1253649 (Thu Apr 8 08:05:48 2021) host-id=1 score=0 vm_conf_refresh_time=1253650 (Thu Apr 8 08:05:48 2021) conf_on_shared_storage=True maintenance=False state=EngineUnexpectedlyDown stopped=False timeout=Thu Jan 15 20:23:29 1970 –== Host vhost2.yhmk.lan (id: 2) status ==– conf_on_shared_storage : True Status up-to-date : True Hostname : vhost2.<span style=”background-color: rgb(255, 255, 255); color: rgb(51, 51, 51);”>alatest</span>.lan Host ID : 2 Engine status : {“reason”: “vm not running on this host”, “health”: “bad”, “vm”: “down_unexpected”, “detail”: “unknown”} Score : 3400 stopped : False Local maintenance : False crc32 : 539fc30c local_conf_timestamp : 1253343 Host timestamp : 1253343 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1253343 (Thu Apr 8 08:05:46 2021) host-id=2 score=3400 vm_conf_refresh_time=1253343 (Thu Apr 8 08:05:46 2021) conf_on_shared_storage=True maintenance=False state=EngineDown stopped=False –== Host vhost3.yhmk.lan (id: 3) status ==– conf_on_shared_storage : True Status up-to-date : True Hostname : vhost3.alatest.lan Host ID : 3 Engine status : {“reason”: “bad vm status”, “health”: “bad”, “vm”: “up”, “detail”: “Powering up”} Score : 3400 stopped : False Local maintenance : False crc32 : 4072e0b8 local_conf_timestamp : 1252345 Host timestamp : 1252345 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1252345 (Thu Apr 8 08:05:42 2021) host-id=3 score=3400 vm_conf_refresh_time=1252345 (Thu Apr 8 08:05:42 2021) conf_on_shared_storage=True maintenance=False state=EngineStarting stopped=False ``` Then, wait a moment, can access web portal again, and check the hosts status, alway reports one or more hosts with label `unavaiable as HA score`, but it will dispear later. And I found, sometimes the engine vm will migrated to another nodes whill this problem occur. So, seems the HostedEngine is not stable, always occur this problem, could you please help me with this ? Thanks!

Re: ovirt-hosted-engine-cleanup
by Thomas Hoberg 20 Apr '21

20 Apr '21

ovirt-hosted-engine-cleanup will only operate on the host you run it on. In a cluster that might have side-effects, but as a rule it will try to undo all configuration settings that had a Linux host become an HCI member or just a host under oVirt management. While the GUI will try to do the same with Ansible only, the script seems to do a little more and be more thorough. My guess is that it's somewhat of a leftover from the older 'all scripts' legacy of oVirt, before they re-engineered much of it to fit Ansible. It's not perfect, however. I have come across things that it would not undo, and that were extremely difficult to find (a really clean re-install would then help). There was an issue around keys and certificates for KVM that I only remember as a nightmare and more recently I had an issue with it's ansible scripts inserting an LVM device filter specific for a UID that the HCI setup wizard had created, which then precluded it ever working again after running the *cleanup scripts. All I got was "device excluded by a filter" and only much later I found the added line in /etc/lvm.conf not undone, which caused this nail-biter. But generally that message "Is hosted engine setup finished?" mostly indicates that the four major daemons for HCI still have issues. It all starts with glusterd: If you just added a host in HCI with storage, that would like to be properly healed. AFAIK that doesn't actually preclude already using the machine to host VMs, but in the interest of keeping your head clear, I'd suggest concentrating on getting the storage all clean, with gluster happily showing connectivity all around (gluster volume status all etc.) and 'gluster volume heal <volume> [info]' giving good results. Then you need to check on the services ovirt-ha-broker and ovirt-ha-agent as well as vdsmd via 'servicectl status <servicename>' to see what they are complaining about. I typically restart them in this order to iron out the bumps. As long as you give them a bit of time, restarting them periodically doesn't seem to do any harm, but helps them recover from hangs. And then you simply need patience: Things don't happen immediately in oVirt, because few commands ever intervene into anything directly. Instead they set flags here and there which then a myriad of interlocking state machine gears will pick up and respond to, to do things in the proper order and by avoiding the race conditions manual intervention can so easily cause. Even the fastest systems won't give results in seconds. So have a coffee, better yet, some herbal tea, and then look again. There is a good chance oVirt will eventually sort it out (but restarting those daemons really can help things along, as will looking at those error messages and their potential cause).

Introduction & general question about oVirt
by Nicolas Kovacs 20 Apr '21

20 Apr '21

Hi, I'm a 53-year old Austrian living in Montpezat, a small village in South France. I'm an IT professional with a focus on Linux and free software, and I've been a Linux user since Slackware 7.1. I'm doing web & mail hosting for myself and several small structures like our local school and a handful of local companies. Up until recently these hostings have happened on "bare metal" root servers using CentOS 7. One main server is hosting most of the stuff: WordPress sites, one OwnCloud instance, Dolibarr management software, GEPI learning platform, Postfix/Dovecot mail server, Roundcube webmail, etc. This setup has become increasingly problematic to manage, since applications have more and more specific requirements, like different versions of PHP and corresponding modules. So I decided to split everything up nicely into a series of virtual machines, each one with a nicely tailored setup. I have a couple of sandbox servers, one public and one local, running Oracle Linux 7 (a RHEL clone like CentOS). I played around with it, and KVM-based virtualization already works quite nicely. While looking for documentation, I stumbled over oVirt, which I didn't even know existed until last week. Before I dive head first into it, I'd be curious to know a few general things. 1. Would it be overkill for a small structure like mine? 2. Will I be able to do HA on a series of modest KVM-capable root servers even if they are located in different datacenters across different countries? 3. One problem I couldn't resolve using a bone-headed keep-it-simple KVM setup is backup. For my bare-metal servers I've been using incremental backups using Rsnapshot for years. Here's a blog article I wrote on the subject: https://blog.microlinux.fr/rsnapshot-centos-7/ Unfortunately I can't use this approach with huge QCOW images, at least not without jumping through burning loops. Is there an easy way to perform remote incremental backups with oVirt? BTW, I took a peek at Proxmox and Ceph, but I admit I'm a die-hard RHEL-clone user.

Upgrading single host ovirt "clusters" to v4.5 via command line?
by Gilboa Davara 19 Apr '21

19 Apr '21

Hello all, As the title suggests I have a couple of single-host hyper converged setups, mostly used for testing. As I cannot use the GUI cluster upgrade method on a single host (it requires me to reboot the host, which will require me to shutdown the hosted engine), is there any method to upgrade the cluster / data-center via command line in maintenance=global mode? Beyond that, can I use the same method on my production setups? (multi-node, gluster based setups). Thanks, Gilboa
