Don't forget to run a ping with a size of 8500 and "do not fragment" flag. This will really prove that you are no longer using the small MTU anywhere on the path.

oVirt Enginge Version: 3.5.0.1-1.el6 (yes....I know it's old) VM is running Ubuntu 18.04 with ovirt agent installed.

[ANN] oVirt updates
by Sandro Bonazzola 09 Jul '19

09 Jul '19

oVirt community, Today marks a new day in the 26-year history of Red Hat. IBM has finalized its acquisition of Red Hat, which will operate as a distinct unit within IBM moving forward. What does this mean for Red Hat’s contributions to the oVirt project? In short, nothing. Red Hat always has and will continue to be a champion for open source and projects like oVirt that have played such a large role in driving innovation in the virtualization space. IBM is committed to Red Hat’s independence and role in open source software communities so that we can continue this work without interruption or changes. Our mission, governance, and objectives remain the same. We will continue to execute the existing project roadmap as we’ve been doing since 2011 for the oVirt project. Red Hat associates will continue to contribute to the upstream in the same way they have been. And, as always, we will continue to help upstream projects be successful and contribute to welcoming new members and maintaining the project. We will do this together, with the community, as we always have. If you have questions or would like to learn more about today’s news, I encourage you to review the materials below. Red Hat CTO Chris Wright will host an online Q&A session in the coming days where you can ask questions you may have about what the acquisition means for Red Hat and our involvement in open source communities. Details will be announced on the Red Hat blog [1]. * Press release [2] * Blog from Chris Wright [3] * FAQ [4] Sandro Bonazzola, Manager, Software Engineering [1] https://www.redhat.com/en/blog [2] https://www.redhat.com/en/about/press-releases/ibm-closes-landmark-acquisit… [3] https://www.redhat.com/en/blog/red-hat-and-ibm-accelerating-adoption-open-s… [4] https://community.redhat.com/blog/2019/07/faq-for-communities/

Managed Block Storage
by dan.poltawski＠tnp.net.uk 09 Jul '19

09 Jul '19

I'm testing out the managed storage to connect to ceph and I have a few questions: * Would I be correct in assuming that the hosted engine VM needs connectivity to the storage and not just the underlying hosts themselves? It seems like the cinderlib client runs from the engine? * Does the ceph config and keyring need to replicated onto each hypervisor/host? * I have managed to do one block operation so far (i've created a volume which is visible on the ceph side), but multiple other operations have failed and are 'running' in the engine task list. Is there any way I can increase debugging to see whats happening?

Storage domain format version info
by Gianluca Cecchi 09 Jul '19

09 Jul '19

Hello, part of updating a DC from 4.2 to 4.3 consists in updating format of data storage domains from V4 to V5. Questions: - where can I find list of differences between V4 and V5? And in general between previous ones? - can I force only a particular storage domain to remain in V4 while having the other ones upgraded to V5, for any reason? Or the reverse: update only one of the defined domains? Eg on oVirt web site I only found this for V4 https://www.ovirt.org/develop/release-management/features/storage/storage_d… with mention about Qcow2 v3 (link broken.. one ot the upstream pages for it here: https://wiki.qemu.org/Features/Qcow3 ) that should give near raw performance with advantages of qcow2 format... Thanks, Gianluca

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

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

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

Anaconda crashing on start while trying to Install oVirt Node on bare metal
by rubentrindade＠live.com 05 Jul '19

05 Jul '19

Hello there! I'm trying to install an oVirt node(the most stable recent one) on a machine(just in case you didn't figure from the title :P) and anaconda just crashes \o/ I've tried to start anaconda in text mode, but the error is the exact same. Here's a screenshot of the event(text mode, although it shouldn't matter): https://i.imgur.com/ihO1xWP.jpg The only "disk" attached to the machine has no partitions, it's absolutely clean. The machine in question is a PowerEdge M520, if that matters, and I'm trying to install on top of a pair of 32GB mirrored SD cards. I installed CentOS7 on a machine that's virtually the same(they're the exact same, but aren't the same machine) and didn't have any problem. I just have no idea. Never encountered such problem. So any help would be very appreciated. Thanks ^^

Re: [ovirt-devel] USB on host support?

I'm having a similar problem. The passtrough needs 2 steps, the first is to attach the host device to the VM, but if you don't enable the spice usb the vm fails to start. I don't know if the USB works straight from the host device or if it depends on the spice console. In my case, a device that work in a windows 10 pc doesn't work in a windows 10 vm.

4.3 won't upgrade engine in standalone KVM VM: low_custom_compatibility_version 'agent03'
by Richard Chan 05 Jul '19

05 Jul '19

Hi, I am running 4.2 engine in a standalone libvirt KVM VM (running on a hypervisor that is not part of the oVirt infrastructure); i.e., I am not using hosted engine but still running engine in a VM. Now 4.3 won't upgrade inside this libvirt KVM VM: Failed to execute stage 'Setup validation': Cannot upgrade the Engine due to low custom_compatibility_version for virtual machines: ['agent03']. Please edit this virtual machines, in edit VM dialog go to System->Advanced Parameters -> Custom Compatibility Version and either reset to empty (cluster default) or set a value supported by the new installation: 4.1, 4.2, 4.3. engine-setup has probably detected that it is running inside a VM: 1. Where did it get 'agent03' string from 2.
