IPv6 Support
by David White 28 Jun '21

28 Jun '21

Hello, Reading https://www.ovirt.org/documentation/administration_guide/index.html#IPv6-ne…, I see this tidbit: - Dual-stack addressing, IPv4andIPv6, is not supported - Switching clusters from IPv4 to IPv6 is not supported. If I'm understanding this correctly... does that mean I cannot run some VMs with IPv4, and other VMs with IPv6, in the same cluster? If so, that's incredibly disappointing and frustrating. Is Dual-stack addressing a possible feature request? IPv4 addresses are expensive... and I have a couple of customers who only needs IPv6, so would really prefer to avoid having to pay for IPv4 addresses for them. Sent with ProtonMail Secure Email.

Question about Template and Storage Domain
by Nur Imam Febrianto 27 Jun '21

27 Jun '21

Hi, Want to ask about template. For example I have a several template (with disk) stored in some Storage Domain. If I create a VM from the template, and when I change the parameter of cloned disk into another storage domain (different with where the template are stored). The VM always failed to be created. This only occurs in VM creation phase, if I create the VM at same storage domain where the templates are stored, it created successfully. Is this are “normal” behavior ? Thanks before. Regards, Nur Imam Febrianto

There was an initiative about supporting it started some time ago from openEuler ovirt SIG. I didn't got any further updates on this topic, looping in those who I remember being looking into it.

Mount Export Domain only temporary
by jb 25 Jun '21

25 Jun '21

Hello community, We use a NFS export domain for full backups. Sometimes I have to restart the NFS file server, but when I just restart that server, without doing anything in oVirt (I guess normally I should put the domain in maintenance mode), it can happen that hosts and VMs a crashing. I had one time even the issue, that after a crash one XFS file system on one host got damage and I had to fix that. My though was now, because I make only one time a week a VM full backup, I only mount the export domain in this time. Is there an easy way to do this, with the API? Or would you have a other hint, how to solve this issue? Have a good day! Jonathan

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

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.

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?

[ANN] oVirt 4.4.7 Fifth Release Candidate is now available for testing
by Lev Veyde 24 Jun '21

24 Jun '21

oVirt 4.4.7 Fifth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.7 Fifth Release Candidate for testing, as of June 24th, 2021. This update is the seventh in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.7 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.7 (redeploy in case of already being on 4.4.7). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.4 or similar * CentOS Stream 8 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.4 or similar will need the upcoming next batch update, providing an updated sanlock package. * CentOS Stream 8 * oVirt Node 4.4 based on CentOS Stream 8 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

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
