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

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

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

tun: unexpected GSO type: 0x0, gso_size 1368, hdr_len 66
by lejeczek 01 Jun '20

hi everyone, With 4.4 I get: ... tun: unexpected GSO type ... It happens to a "third-party" kernel, namely: 5.6.15-1.el8.elrepo.x86_64 on Centos 8. I wonder if anybody sees the same or similar and I also wonder if I should report it somewhere in Bugzilla as "heads-up" towards new kernels?

Problem with Ovirt Machines
by aigini82＠gmail.com 31 May '20

31 May '20

Hi, Our company uses Ovirt to host some of its virtual machines. The version used is 4.2.6.4-1.el7. There are about 36 virtual hosts in it. The specifications used for the host machine is 30G RAM and 6 CPUs. Some of the VMs in the ovirt host run with 4 CPUs. Some with 2 CPUs. The problem I face now is that recently there was a need for high CPU and memory specs to setup a VM for DR. I created a VM with 16G RAM and 6 CPUs, without checking the CPUs available in the host first. After DR, the VM was brought down already. Then later another person in the team brought the VM back up for a different DR use, for a much larger DB restoration purpose. This caused the VM to pause due to storage error. And then worse things happened, whereby 2 other VMs inadvertently went down. Although I assumed that this was caused by storage errors/problems, the senior admins in the team concluded that the problem was due to fencing because of the max allotted CPU for the host being used for the VM. Now what I need to know is how to properly allocate CPU resources to a host to run multiple virtual machines in it like the situation above. I even tried to look for errors in vdsm.log, but this log was not available in the host machine nor in the affected VM. My colleague asked me to check "Events" section of the ovirt management interface to see past the past events. However, I don't find much details about the fencing activity or how the fencing occurred or what caused the fencing. And how did they conclude that the CPU count caused the fencing and not the storage?

Failed to add storage domain

Hi! I have installed oVirt using the iso ovirt-node-ng-installer-4.3.2-2019031908.el7. I the did run the Host-engine deployment through Cockpit.

OVirt Upgrade from 4.3 to 4.4 - Hosted engine
by ccesario＠blueit.com.br 30 May '20

30 May '20

Hello, Could someone please inform if Upgrade from OVirt 4.3 to 4.4 when using Hosted engine is it supported !? According the documentation https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_from_4-3 the upgrade procedure make reference only to "standalone engine". If it is supported, what is correct steps to do it? Best regards Carlos
