Ovirt Secure boot issues
by Strahil 08 Jul '19

08 Jul '19

Hello All, I would like to ask any of you to do a simple test. Please install a linux on a VM with Secure boot and after the install wizzard is over -power it off and then on. Here is what I have observed: 1. UEFI forgets the certificates after a poweroff and asks for the openSUSE certificate every time. Rebooting from the VM doesn't cause any problems till nextg boot. 2. RHEL8 grub menu consists only of 'System setup'. When you select it - you are sent to the UEFI menu. If you select continue - everything is fine. Poweroff + Poweron makes everything to repeat. Do you observe the same issues. If I'm not the only one hitting this - I will open a bug, otherwise I will try to further debug this. Best Regards, Strahil Nikolov

Hi there, I have a problem, Last week I lost connectivity a VM with OS Windows server 2008 I access to check it and in ovirtmanager that VM is power on and I could login it, but there was no ping to other VM machines So I restarted VM and I recovery connectivity. Today It shows the same scenario with same VM. I checked log from ovirtmananer and ovirt node from running VM but I didnt find any error. Where can I find out more ? I have a Ovirtmanager 4 and a Ovirtnode 4.1 [image: imagen.png] -- Julio Cesar Bustamante.

Yes, But I thought that cockpit should prevent creation of the gluster volume 'engine' as it is too small. @Dev Do we have such control ?

HE deployment failing
by Parth Dhanjal 08 Jul '19

08 Jul '19

Hey! I'm trying to deploy a 3 node cluster with gluster storage. After the gluster deployment is completed successfully, the creation of storage domain fails during HE deployment giving the error: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Error: the target storage domain contains only 46.0GiB of available space while a minimum of 61.0GiB is required If you wish to use the current target storage domain by extending it, make sure it contains nothing before adding it."} I have tried to increase the disk size(provided in storage tab) to 90GiB. But the deployment still fails. A 50GiB storage domain is created by default even if some other size is provided. Has anyone faced a similar issue? Regards Parth Dhanjal

Re: UI - cannot remove disk whiel system is running
by Strahil 07 Jul '19

07 Jul '19

Everything ended well - despite the warning 'do not shutdown' I powered off and powered on the VM. This action allowed me to trigger a snapshot deletion (again) and it completed successfully. Removing the disk of interest also completed successfully. So, I got a happy ending.

I think I'm getting closer. It seems the snapshot of the VM did not get deleted and that might be the problem. Can someone give me a hint how to remove the snapshot as I get an error: Cannot remove Snapshot. The following disks are in ILLEGAL status: uyuni-OS-Disk1 - please remove them and try again. Yet, removal of the disk cannot happen as I got: Cannot detach Virtual Disk. The disk is already configured in a snapshot. In order to detach it, remove the disk's snapshot. This seems like 'Catch 22' .

UI - cannot remove disk whiel system is running
by Strahil 07 Jul '19

07 Jul '19

Hello All, I have changed my system layout and the old disk is removed (echo 1 > /sys/block/sdX/device/delete) from OS, but UI complains when I try to remove with the following error: Error while executing action: Cannot remove Virtual Disk. At least one of the VMs is not down. Is it a limitation of oVirt ? If so, I will open an enhancement entry in bugzilla. As far as I remember KVM allowed me to make such stuff without any issues so far. Best Regards, Strahil Nikolov

VM snapshot - some info needed
by Strahil Nikolov 07 Jul '19

07 Jul '19

Hello Community, I have noticed that if I want a VM snapshot with memory - I get a warning "The VM will be paused while saving the memory" .Is there a way to make snapshot without pausing the VM for the whole duration ? I have noticed that it doesn't matter if VM has qemu-guest-agent or ovirt-guest-agent. Thanks in advance for sharing your thoughts. Best Regards,Strahil Nikolov

Experience 4.1.x -> 4.2.8 -> 4.3.4 upgrade lessons
by Richard Chan 07 Jul '19

07 Jul '19

Hi oVirters, Did a 4.1 - > 4.2.8 -> 4.3.4 upgrade in two hops. Here is my experience, hope it can save you some pain. Gotchas 1. For shutdown VMs, their disks were deactivated (though still attached) 2. For shutdown VMs, their NICs were "Up" but "Unplugged" 3. VM Custom Compatibility Version is hard to find. (If it is too old say 3.6, 4.1) they won't start up. The location is: VM -> Edit -> System -> Advanced Parameters (click this) "Advanced Parameters" is an expandable widget that is quite small when collapsed. When it is expanded then you will see "Custom Compatibility Version" 4. Storage Domain migration to V5: I use a NFS storoage domain. This is migrated to the "V5" format and a lot of cleanup is done. If you have stray files or images not owned by 36:36 (vdsm:kvm on my NFS server), the V5 upgrade will fail, there will be no SPM, and the Data Center will oscillate between Non-responsive and Contending. Why would there be non 36:36 uid/gid files? This is a long story, but from the older 3.x days when there was less functionality, we would sometimes directly manipulate the filesystem and/or qcow2 images using guestfish or equivalent tools which would change the owner to qemu:qemu. Forgetting to chown back to vdsm:kvm is a recipe for pain. Cheers! -- Richard Chan
