Ovirt 4.4 Migration assistance needed.
by Strahil Nikolov 05 Jun '20

05 Jun '20

Hello All, I would like to ask for some assistance with the planing of the upgrade to 4.4 . I have issues with the OVN (doesn't work at all), thus I would like to start fresh with the HE. The plan so far (downtime is not an issue) : 1. Reinstall the nodes one by 1 and rejoin them in the Gluster TSP 2. Wipe the HostedEngine's gluster volume 3. Deploy a fresh hosted engine 4. Import the storage domains (gluster) back to the engine and import the VMs Do you see any issues with the plan ? Any problems expected if the VMs do have snapshots? What about the storage domain version ? Thanks in Advance. Best Regards, Strahil Nikolov

Gluster error in server log.
by Krist van Besien 05 Jun '20

05 Jun '20

Hello all, On my ovirt HC cluster I constantly get the following kinds of errors: From /var/log/ovirt-engine/engine.log 2020-06-05 10:38:36,652+02 WARN [org.ovirt.engine.core.vdsbroker.gluster.GlusterVolumesListReturn] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-15) [] Could not associate brick 'on1.ws.kri.st:/gluster_bricks/vmstore/vmstore' of volume 'dab47af2-16fc-461d-956e-daab00c8489e' with correct network as no gluster network found in cluster 'a8a38ffe-a499-11ea-9471-00163e5ffe63' Normally you get these errors if you forgot to define and assign a storage network. However I do have a storage network, have assigned it to the interface used by gluster on each host, and have set it as the “gluster” network in the default cluster. So why am I still getting this error? Krist Vriendelijke Groet | Best Regards | Freundliche Grüße | Cordialement Krist van Besien krist.vanbesien(a)gmail.com

oVirt 4.4 node via PXE and custom kickstart
by Michael Thomas 04 Jun '20

04 Jun '20

I'm trying to customize a node install to include some local management and monitoring tools, starting with puppet, following the instructions here: https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_us… The installation of the ovirt node works, and I can deploy the engine once it's running. However, while the extra steps in the %post section of my kickstart are working, any additional 'repo' and %package settings seem to get ignored (even though they were copied from known working kickstart files). What kickstart customizations are supported when deploying a node via PXE? My PXE menu looks like this: menuentry 'Ovirt node' { linuxefi ovirt/vmlinuz ip=dhcp ks=http://10.13.5.13/kickstart/ovirt.cfg ksdevice=link initrd=ovirt/initrd.img inst.stage2=http://10.13.5.13/rhvh initrdefi ovirt/initrd.img } My kickstart file is as follows: liveimg --url=http://10.13.5.13/rhvh/ovirt-node-ng-image.squashfs.img clearpart --all --initlabel autopart --type=thinp zerombr rootpw --plaintext ovirt timezone --utc America/Chicago text reboot # This will need to be updated to point to the 'frozen' snapshot, when available repo --install --name="EPEL" --baseurl=http://10.13.5.13/mirror/linux/epel/8/Everything/x86_64 --cost=99 repo --install --name="Puppet" --baseurl=http://10.13.5.13/mirror/linux/puppetlabs/puppet6/el/8/x86_64 --cost=98 %packages puppet-agent %end %post --erroronfail nodectl init echo "This is a test" > /etc/test.txt %end --Mike

oVirt 4.4 install fails
by Me 04 Jun '20

04 Jun '20

Hi All Not sure where to start, but here goes. I'm not totally new to oVirt, I used RHEV V3.x in production for several years, it was a breeze to setup. Installing 4.4 on to a host with local SSD and FC for storage. Issue 1, having selected the SSD for install which has failed 4.4 beta on it (several times), I reclaim the space and after a few minutes of not being able to enter a root password on the next install screen, it fails as it can't delete the data on the SSD! Yes, really tried this several times, choosing the recover option and getting a prompt, fdisk /dev/sda delete the two partitions created by oVirt and I can install. This was the case with the beta I tried a few weeks ago too. Having reconfigured the switch attached the the host as a dumb 10GBE port as the enterprise OS installer still doesn't appear to support anything more advanced like teaming and VLANS, I have the initial install on the single SSD and a network connection. Issue 2, I use FF 72.0.2 on Linux x64 to connect by https://hostname:9090 to the web interface, but I can't enter login details as the boxes (everything) are disabled???? There is no warning like "we don't like your choice of browser", but the screen is a not very accessible dark grey on darker grey (a poor choice in what I thought were more enlightened times) so this maybe the case. I have disabled all security add-ons in FF, makes no difference. Any suggestions? M

basic infra and glusterfs sizing question
by Jiří Sléžka 04 Jun '20

04 Jun '20

Hello, I am just curious if basic gluster HCI layout which is suggested in cockpit has some deeper meaning. There are suggested 3 volumes * engine - it is clear, it is the volume where engine vm is running. When this vm is 51GB big how small could this volume be? I have 1TB SSD storage and I would like utilize it as much as possible. Could I create this volume as small as this vm is? Is it safe for example for future upgrades? * vmstore - it make sense it is a space for all other vms running in oVirt. Right? * data - which purpose has this volume? other data like for example ISOs? Direct disks? Another infra question... or maybe request for comment I have small amount of public ipv4 addresses in my housing (but I have own switches there so I can create vlans and separate internal traffic). I can access only these public ipv4 addresses directly. I would like to conserve these addressess as much as possible so what is the best approach in your opinion? * Install all hosts and HE with management network on private addressess * have small router (hw appliance with for example LEDE) which will utilize one ipv4 address and will do NAT and vpn for accessing my internals vlans. + looks like simple approach to me - single point of failure in this router (not really - just in case oVirt is badly broken and I need to access internal vlans to recover it) * have this router as virtual appliance inside oVirt (something like pfSense for example) + no need hw router + not sure but I could probably configure vrrp redundancy - still single point of failure like in first case * any other approach? Could ovn help here somehow? * Install all hosts and HE with public addresses :-) + access to all hosts directly - 3 node HCI cluster uses 4 public ip addressess Thanks for your opinions Cheers, Jiri

Ovirt 4.4 HC gluster issues on new CentOS 8 node (cluster still in 4.3 compatibility level)
by jillian.morgan＠primordial.ca 04 Jun '20

04 Jun '20

I've successfully migrated to a new 4.4 engine, now managing the older 4.3 (CentOS 7) nodes. So far so good there. I installed a new CentOS 8 node w/ 4.4, joined it to the Gluster peer group, and it can see all of the volumes, but the node won't go into Online state in the engine because of apparent gluster-related VDSM errors: Status of host butter was set to NonOperational. Gluster command [<UNKNOWN>] failed on server <UNKNOWN>. VDSM butter command ManageGlusterServiceVDS failed: The method does not exist or is not available: {'method': 'GlusterService.action'} I haven't been able to find anything in the VDSM or Engine logs that give me any hint as to what's going on (besides just repeating that the "GlusterSerice.action" method doesn't exist). Anybody know what I'm missing, or have hints on where to dig to debug further?

Those are the last few characters of the admin password. Note that I don't mean the root password to the VM, but the one for the "admin" user of the web interface. I added some debug lines to the Ansible play to see the answerfile that was being generated. OVESETUP_CONFIG/adminPassword=str:&6&yGfcWf#b%JUUj Apparently engine-setup can no longer handle an answerfile with a "%" character in it. This same password worked in 4.3. Once I changed the admin password, installation progressed normally.

Import VM from export domain using oVirt-4.4
by Joop 03 Jun '20

03 Jun '20

Hi All, I'm testing a shiny new oVirt-4.4.02, selfhosted engine HCI gluster, and found a problem when importing my VMs from an export domain. Import is OK but can't start the VM due to the fact that the BIOS is set to Legacy. Manually setting the BIOS type to Cluster Default, through VM properties, will let the VM start. I couldn't find anything about it in the ReleaseNotes As a side note: using gluster still doesn't install gluster-ansible-roles and glusterfs-server and vdsm-gluster or checks for its existance. See also another user who reported problems due to the latter not being installed, had the same experience. Regards, Joop

VM Networking
by Anton Louw 02 Jun '20

02 Jun '20

Hi Everybody, I had a strange incident today.. One of my nodes restarted (Still busy investigating why), but my VMs powered own and moved to different nodes, the only issue is, it seemed to have changed the vlan ID on the NICs? Has anybody seen this before? I am just trying to establish if this was changed on the node networking side, or inside of the VM. Thank you Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

Problem with oVirt 4.4
by minnie.du＠vinchin.com 02 Jun '20

02 Jun '20

Hello, We have met a problem when testing oVirt 4.4. Our VM is on NFS storage. When testing the snapshot function of oVirt 4.4, we created snapshot 1 and then snapshot 2, but after clicking the delete button of snapshot 1, snapshot 1 failed to be deleted and the state of corresponding disk became illegal. Removing the snapshot in this state requires a lot of risky work in the background, leading to the inability to free up snapshot space. Long-term backups will cause the target VM to create a large number of unrecoverable snapshots, thus taking up a large amount of production storage. So we need your help.

Problems creating bricks for new Gluster storage 4.4
by Jaret Garcia 02 Jun '20

02 Jun '20

Hi guys I'm trying to deploy a new ovirt environmet based in version 4.4 so I set up the following: 1 engine sever (stand alone) Version : 4.4.0.3 3 host servers (32 GB RAM, 2CPUs 8 core Xeon 5160, 500GB OS drive, 1 storage 8TB drive and 1 SSD 256GB (I'm trying to create a brick with SSD cache with no success) Detail of versions running on servers [ OS Version: RHEL - 8 - 1.1911.0.9.el8 OS Description: oVirt Node 4.4.0 Kernel Version: 4.18.0 - 147.8.1.el8_1.x86_64 KVM Version: 4.1.0 - 23.el8.1 LIBVIRT Version: libvirt-5.6.0-10.el8 VDSM Version: vdsm-4.40.16-1.el8 SPICE Version: 0.14.2 - 1.el8 GlusterFS Version: glusterfs-7.5-1.el8 CEPH Version: librbd1-12.2.7-9.el8 Open vSwitch Version: openvswitch-2.11.1-5.el8 Nmstate Version: nmstate-0.2.10-1.el8 ] Engine server working fine, all 3 host servers already part of the default cluster as hypervisors, then when I try to create a brick in any of the servers, using the 8TB HHDD and SSD as cache the process fails, in the GUI it just says "failed to creat brick on host" However in engine log as well as in brick-setup log I see: "err" : " Physical volume \"/dev/sdc\" still in use\n" "failed" : true,, (sdc in this case is the 8TB HHDD) Attached files of both logs.

Mixing OS versions
by Stack Korora 01 Jun '20

01 Jun '20

Greetings, We've been using Scientific Linux 7 quite successfully with oVirt for years now. However, since there will not be a SL7 we are transitioning new servers to CentOS8. I would like to add a new oVirt hypervisor node. How bad of an idea is it to have a 8 system when the rest are 7 even though the version of oVirt will be the same? Thanks!

ovirt imageio problem...
by matteo fedeli 01 Jun '20

Hi! I' installed CentOS 8 and ovirt package following this step: systemctl enable --now cockpit.socket yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm yum module -y enable javapackages-tools yum module -y enable pki-deps yum module -y enable postgresql:12 yum -y install glibc-locale-source glibc-langpack-en localedef -v -c -i en_US -f UTF-8 en_US.UTF-8 yum update yum install ovirt-engine engine-setup (by keeping all default) It's possible ovirt-imageio-proxy service is not installed? (service ovirt-imageio-proxy status --> not found, yum install ovirt-imageio-proxy --> not found) I'm not able to upload iso... I also installed CA cert in firefox...

Issues deploying 4.4 with HE on new EPYC hosts
by Mark R 01 Jun '20

01 Jun '20

Hello all, I have some EPYC servers that are not yet in production, so I wanted to go ahead and move them off of 4.3 (which was working) to 4.4. I flattened and reinstalled the hosts with CentOS 8.1 Minimal and installed all updates. Some very simple networking, just a bond and two iSCSI interfaces. After adding the oVirt 4.4 repo and installing the requirements, I run 'hosted-engine --deploy' and proceed through the setup. Everything looks as though it is going nicely and the local HE starts and runs perfectly. After copying the HE disks out to storage, the system tries to start it there but is using a different CPU definition and it's impossible to start it. At this point I'm stuck but hoping someone knows the fix, because this is as vanilla a deployment as I could attempt and it appears EPYC CPUs are a no-go right now with 4.4. When the HostedEngineLocal VM is running, the CPU definition is: <cpu mode='custom' match='exact' check='full'> <model fallback='forbid'>EPYC-IBPB</model> <vendor>AMD</vendor> <feature policy='require' name='x2apic'/> <feature policy='require' name='tsc-deadline'/> <feature policy='require' name='hypervisor'/> <feature policy='require' name='tsc_adjust'/> <feature policy='require' name='clwb'/> <feature policy='require' name='umip'/> <feature policy='require' name='arch-capabilities'/> <feature policy='require' name='cmp_legacy'/> <feature policy='require' name='perfctr_core'/> <feature policy='require' name='wbnoinvd'/> <feature policy='require' name='amd-ssbd'/> <feature policy='require' name='skip-l1dfl-vmentry'/> <feature policy='disable' name='monitor'/> <feature policy='disable' name='svm'/> <feature policy='require' name='topoext'/> </cpu> Once the HostedEngine VM is defined and trying to start, the CPU definition is simply: <cpu mode='custom' match='exact' check='partial'> <model fallback='allow'>EPYC</model> <topology sockets='16' cores='4' threads='1'/> <feature policy='require' name='ibpb'/> <feature policy='require' name='virt-ssbd'/> <numa> <cell id='0' cpus='0-63' memory='16777216' unit='KiB'/> </numa> </cpu> On attempts to start it, the host is logging this error: "CPU is incompatible with host CPU: Host CPU does not provide required features: virt-ssbd". So, the HostedEngineLocal VM works because it has a requirement set for 'amd-ssbd' instead of 'virt-ssbd', and a VM requiring 'virt-ssbd' can't run on EPYC CPUs with CentOS 8.1. As mentioned, the HostedEngine ran fine on oVirt 4.3 with CentOS 7.8, and on 4.3 the cpu definition also required 'virt-ssbd', so I can only imagine that perhaps this is due to the more recent 4.x kernel that I now need HE to require 'amd-ssbd' instead? Any clues to help with this? I can completely wipe/reconfigure the hosts as needed so I'm willing to try whatever so that I can move forward with a 4.4 deployment. Thanks! Mark
