Re: oVirt 4.2 how to upgrade
by Strahil Nikolov 24 Jun '21

Theoretically you most probably can, but you take the risk of being vulnerable to split-brain. Keep in mind that you can:- update gluster to the same version that is used on oVirt 4.4- update oVirt to 4.3.10 as this is the most tested migration scenario- reduce the volume and remove that 3rd node (don't forget to peer detach)- reinstall with EL8 and install gluster (same version) again. Add the brick and qait for the heal- create a new volume for the new HE- Stop the old HE and deploy the new one from the backup- Add the hosts to the new HE and migrate some of the VMs to free one of the old hosts- Reinstall the remaining hosts (one by one) to EL8 Best Regards,Strahil Nikolov On Thu, Jun 24, 2021 at 14:28, Fedele Stabile<fedele.stabile(a)fis.unical.it> wrote: I have a 3 node oVirt 4.2.1 cluster, i'm using a self-hosted engine architecture and storage-engine is on a glusterfs replica 3 of the cluster.

Expected behavior when link of required VM networks down
by Gianluca Cecchi 24 Jun '21

24 Jun '21

Hello, suppose I have a cluster with required VM logical network setup. Suppose on hosts I have configured a bonding device with this logical network mapped on it. Suppose an active host for any reason loses the physical connectivity on this bond (both links down or problems with new network config impacting the bond, ecc) So from the VMs point of view, those having a vnic on this logical network will lose the connectivity, but I think they will not detect link down, correct? Is there any expected default action oVirt will take in respect of this scenario or not? Of course I expect to see events with messages about link down. But any automatic action such as live migration of impacted VMs for example? Any configurable one at oVirt level? Thanks, Gianluca

I have a 3 node oVirt 4.2.1 cluster, i'm using a self-hosted engine architecture and storage-engine is on a glusterfs replica 3 of the cluster. The oldest CPU is SandyBridge family (E5-2609) and incidentally it has connectivity problems with IPMI NIC, but Hosted Engine HA is enabled and working. May I reduce the glusterfs replica to 2 and use one of the 3 nodes to begin the installation of ovirt 4.4 on that node? Fedele

oVirt 4.4.5 - Windows Server 2003 VM Reboot problems
by simon＠justconnect.ie 24 Jun '21

24 Jun '21

Hi All, I've had to migrate a Windows Server 2003 R2 VM from VMWare to oVirt which I have successfully managed to get running. The problem I have is if I try to reboot from the OS I receive the following message after the VM shuts down but doesn't reboot: "Exit message: Lost connection with qemu process." Also any attempt to either shutdown or reboot from oVirt Manager has no effect. I realize that this OS is not supported in the current oVirt version, but is there something I am missing to get it working 'unsupported' please? Regards Simon...

I am going to buy 4 new SSD disks to replace the 4 disks of the defective raid0. When I'm going to erase the faulty raid0 and create the new raid with the new disks on the raid controler, how do I add in ovirt so that they resynchronize with the other bricks data?

Problems moving vm & templates between oVirt 4.3 & 4.4
by Guillaume Pavese 23 Jun '21

23 Jun '21

On ovirt 4.4.6, I created a VM and made a template from it. I would like to copy them to oVirt 4.3.7 & 4.3.10 DCs - I saw that Export Domain is deprecated. I tried exporting the VM & template to an Export Domain anyway but, after attaching the Export DOmain on my ovirt 4.3.7 DC, both VM and Template imports failed. The Template import failed immediately without any errors visible in the UI, The VM import failed with the message "General command validation failure." - I tried to do it through a Data Domains as recommended, but: If created on oVirt 4.4.6, I get a Format V5 DataDomain that my oVirt 4.3.7 refuses to import. If created first on the oVirt 4.3 DC, I get a Format V4 Domain. But then importing it on the oVirt 4.4 DC, I get the message: "Approving this operation will upgrade the Storage Domain format from 'V4' to 'V5'. Note that you will not be able to attach it back to an older Data Center." In "Administration > Providers" everything seems supported, from XEN / KVM and even VMware (we have used all three with some success). However oVirt is the obvious missing option... I still have to try "Export as OVA", is that the only supported way?

Import Ge0-Replicated Storage Domain fails
by simon＠justconnect.ie 22 Jun '21

22 Jun '21

Hi All, I have 2 independent Hyperconverged Sites/Data Centers. Site A has a GlusterFS Replica 3 + Arbiter Volume that is Storage Domain data2 This Volume is Geo-Replicated to a Replica 3 + Arbiter Volume at Site B called data2_bdt I have simulated a DR event and now want to import the Ge0-Replicated volume data2_bdt as a Storage Domain on Site B. Once imported I need to import the VMs on this volume to run in Site B. The Geo-Replication now works perfectly (thanks Strahil) but I haven't been able to import the Storage Domain. Please can someone point me in the right direction or documentation on how this can be achieved. Kind Regards Shimme...

importing vm's from storage pool from 4.1.6.2-1 in to 4.4.6 fails due to lingering snapshot configuration in source
by Charles Kozler 22 Jun '21

22 Jun '21

I know the subject is a bit wordy but let me try to explain I have a 4.1 installation that I am migrating to 4.4. I placed the storage domain into maintenance and then rsync'ed it to the storage I am using for 4.4. In 4.4 I import the domain and it comes in fine, however, when trying to import some VM's it fails because it says it cannot find a disk. The disk ID's I cannot find anywhere in 4.1 or 4.4 so I opened OVF_STORE after upgrading the pool in 4.4 and look at the ovf file for some of the VM's that are failing to import I see this in the ovf configuration file - <Section xsi:type="ovf:SnapshotsSection_Type"> <Snapshot ovf:id="e300fa3b-eee4-4b96-9103-45115081db57"> <Type>ACTIVE</Type> <Description>Active VM</Description> <CreationDate>2019/12/19 16:47:48</CreationDate> <Memory>07d3447c-c640-4163-9cf1-74ce126d702a,59b5cfdf-015b-0333-004b-000000000397,8c48ea33-dc34-403a-90d2-a3e78776404c,1757809b-9685-4315-a92e-3ea82dc6d8a8,94a2c2b3-e02e-4b05-80eb-6f4b7a9701e7,248a9fd1-61f0-4c5a-b6ab-4630d433c6fa</Memory> </Snapshot> </Section> </Content> </ovf:Envelope> These are the disk ID's I can see failing to import in engine.log I am aware that importing a VM cannot support snapshots and have found multiple mailing list posts around this, however, I do not have any snapshots visible in 4.1 UI. I also tried modifying OVF_STORE by untar'ing it and editing the ovf files directly, however, this does not work as it ends up overwritten by ovirt with the previous configuration Any ideas? As noted, I cannot see any snapshots listed in 4.1 source pool so I therefore cannot remove this stale configuration from the source and upon importing in to 4.4 it fails because it cannot find the disks I tried import partial and that still fails which to me seems like a bug because the idea of the import partial is to still register the VM even if it cant find disks I also tried scanning domain for disks and update OVF's in the UI and it does not help anything -- *Notice to Recipient*: https://www.fixflyer.com/disclaimer <https://www.fixflyer.com/disclaimer>

Having installed oVirt 4.4.4 HCI 3 node cluster, the Grafana 'Monitoring Portal' was not visible on the Default page. It appears that Grafana is installed but not configured.

Replacing hosted engine on Gluster
by Chris Adams 22 Jun '21

22 Jun '21

I've run oVirt on iSCSI storage for years, and I've had to replace the hosted engine a couple of times (upgrade from CentOS 6 to 7, then moving to new storage). I'm looking at oVirt on hyperconverged Gluster storage. I see pages about how to replace a host, but how do you replace the engine when needed? Is it possible to connect a new hosted engine to the existing Gluster storage? I'm just trying to understand all the differences of iSCSI vs. Gluster before deploying it for real; if there's info online that I missed, feel free to point me to it. Thanks! -- Chris Adams <cma(a)cmadams.net>

Recovering from corrupted hosted-engine

Hi Guys, We had a 2-node self-supported RHEV cluster that we used for our development environment. We're in the middle of a migration from RHEV over to VMware - one host has already been converted to VMware and we have actively been running VM migrations over to VMware. During the migration, we had an extended power outage and had to improperly shut down the RHEV host. Since bringing it back up we've not been able to start the hosted-engine. Each time we try to start the hosted engine we're getting the following messages: ## START [root@bmrhev01 ~]# hosted-engine --vm-start VM exists and is down, cleaning up and restarting VM in WaitForLaunch [root@bmrhev01 ~]# hosted-engine --vm-status --== Host bmrhev01 (id: 1) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : bmrhev01 Host ID : 1 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down_unexpected", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : 325ff4b3 local_conf_timestamp : 7920 Host timestamp : 7920 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=7920 (Tue Jun 15 14:59:32 2021) host-id=1 score=3400 vm_conf_refresh_time=7920 (Tue Jun 15 14:59:32 2021) conf_on_shared_storage=True maintenance=False state=EngineStarting stopped=False END ## We've tried rebooting a number of times. Restarting various oVirt services. Nothing appears to be resolving the issue. At this point, the only thing I truly care about is migrating the guest VMs over to VMware. There's nothing else in the RHEV environment I care about. I'm happy to settle with any of the following, providing they can salvage the guest VMs: a) Deleting and redeploying the hosted-engine. b) Abandoning the hosted-engine and some how converting the guest VMs over to VMware. I don't have enough experience to know if any of the above is possible or the repercussions of either of them. Any help from anyone would be very helpful. I'm sorry to be a leach, rather than a contributor. I'm seriously in trouble here and a kind heart would be much appreciated. Thanks, Tim.

oVirt + Gluster issues

Hello, running ovirt 4.4.4.7-1.el8 and gluster 8.3. When i performe a restore of Zimbra Collaboration Email with features.shard on, the VM pauses with an unknown storage error. When I performe a restore of Zimbra Collaboration Email with features.shard off, it fills all the gluster storage domain disks. With older versions of gluster and ovirt the same happens. If I use a NFS storage domain it runs OK. -- Jose Ferradeira http://www.logicworks.pt

/var/log has less then 500MB free space left on

Hi, I started to get messages that /var/log has less then 500MB free space left on out of 8GB. du -h —max-depthh=1 reveals that openswitch log dir consumes 3.6GB, there are files as old as 2018. Node software was installed on fresh CentOS 7.xx from oVirt admin web console. I cleaned this directory, yet question remain - why logrotate service is not running by default on oVirt node? Or this is not recommended? Thanks in advance. Andrei
