Node Unresponsive
by Anton Louw 07 May '20

07 May '20

Hi All, One of my nodes went into a unresponsive state, but the VMs running on that host are still up. I just want to know, can I restart VDSM on that node, or will it impact the running VMs? In another article, somebody restarted the engine, and that resolved their issue. I would like to first test the VDSM and if that does not work, I will restart the engine. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

I'm using oVirt 4.3 (latest ) and able to successfully provision Centos VMs without any problems. When I attempt to provision Ubuntu VMs, they hang at startup. The console shows : ... ... [ 4.010016] Btrfs loaded [ 101.268594] random: nonblocking pool is initialized It stays like this indefinitely. Again, I have no problems with Centos images, but need Ubuntu Any tips greatly appreciated.

by Sandro Bonazzola 07 May '20

07 May '20

The oVirt Project is excited to announce the availability of the first Release Candidate of oVirt 4.4.0 for testing, as of May 6th, 2020 This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics on top of oVirt 4.3. 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 to be used in production. Some of the features included in oVirt 4.4.0 Release Candidate require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 beta yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps postgresql:12 - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed. What’s new in oVirt 4.4.0 Release Candidate? - Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts - Easier network management and configuration flexibility with NetworkManager - VMs based on a more modern Q35 chipset with legacy seabios and UEFI firmware - Support for direct passthrough of local host disks to VMs - Live migration improvements for High Performance guests. - New Windows Guest tools installer based on WiX framework now moved to VirtioWin project - Dropped support for cluster level prior to 4.2 - Dropped SDK3 support - 4K disks support only for file based storage. iSCSI/FC storage do not support 4k disks yet. - Exporting a VM to a data domain - Editing of floating disks - Integrating ansible-runner into engine, which allows a more detailed monitoring of playbooks executed from engine - Adding/reinstalling hosts are now completely based on Ansible - The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. If you manage more than one oVirt instance, OKD or RDO we also recommend to try ManageIQ <http://manageiq.org/>. In such a case, please be sure to take the qc2 image and not the ova image.

Fwd: Ovirt host GetGlusterVolumeHealInfoVDS failed events

Forwarding to oVirt users list. ---------- Forwarded message --------- From: <srivathsa.puliyala(a)dunami.com> Date: Wed, May 6, 2020 at 12:01 PM Subject: Ovirt host GetGlusterVolumeHealInfoVDS failed events To: <infra(a)ovirt.org> Hi, We have a oVirt cluster with 4 hosts and hosted engine running on one of them (all the nodes provide the storage with GlusterFS) Currently there are 53 VMs running. The version of the oVirt-Engine is 4.2.8.2-1.el7 and GlusterFS is 3.12.15. From past 1 week, we seem to have multiple events popping up on Ovirt-UI about the GetGlusterVolumeHealInfoVDS from all the nodes randomly like one ERROR event for every ~13minutes. Sample Event dashboard example: May 4, 2020, 2:32:14 PM - Status of host <host-1> was set to Up. May 4, 2020, 2:32:11 PM - Manually synced the storage devices from host <host-1> May 4, 2020, 2:31:55 PM - Host <host-1> is not responding. Host cannot be fenced automatically because power management for the host is disabled. May 4, 2020, 2:31:55 PM - VDSM <host-1> command GetGlusterVolumeHealInfoVDS failed: Message timeout which can be caused by communication issues May 4, 2020, 2:19:14 PM - Status of host <host-2> was set to Up. May 4, 2020, 2:19:12 PM - Manually synced the storage devices from host <host-2> May 4, 2020, 2:18:49 PM - Host <host-2> is not responding.

May 4, 2020, 1:52:22 PM - VDSM <host-3> command GetGlusterVolumeHealInfoVDS failed: Message timeout which can be caused by communication issues May 4, 2020, 1:39:11 PM - Status of host <host-4> was set to Up. May 4, 2020, 1:39:11 PM - Manually synced the storage devices from host <host-4> May 4, 2020, 1:39:11 PM - Host <host-4> is not responding.

Host cannot be fenced automatically because power management for the host is disabled. May 4, 2020, 1:12:51 PM - VDSM <host-1> command GetGlusterVolumeHealInfoVDS failed: Message timeout which can be caused by communication issues and so on..... When I look at the Compute > Hosts dashboard, I see the host status to be DOWN when VDSM event (GetGlusterVolumeHealInfoVDS failed) is popped and automatically the host status is set to UP within no time. FYI: when host status is DOWN, the VM's running on that host are not migrating and everything is running perfectly fine. This is happening all day. Is there something I can troubleshoot?

Hi, oVirt website accumulated a good amount of broken links over the years. You can see them listed in this etherpad: https://review.rdoproject.org/etherpad/p/SLEq1-6FwW9aw7344eRr You can help fixing the links by edit text files written in markdown language, it's pretty easy to understand and can be done even by somebody without any development skill. This is a good chance to contribute back to oVirt project, looking forward to review your patches at https://github.com/oVirt/ovirt-site !

Hello, supposing to be already at 4.3.9 level and to have CentOS 7.7 based hosts, are there any blocking factors to update them to 7.8, just released some days ago? Thanks, Gianluca

NFS storage domain forced to use /exports/data ?
by kelley bryan 06 May '20

06 May '20

Hello Should the documentation point out that the /exports/data mount point is hard coded in ovirt-hosted-engine-setup-ansible-create_storage_domain.yaml. I think some Data Centers will want to use a different mount path or Did I miss a prompt or entry in the Deployment screen for Hosted-engine-deployment? Bryan

Unable to import CA certificate list
by Sakari Poussa 06 May '20

06 May '20

Hi, I am using 4.4 beta4 and not able to add new hosts to the datacenter. Also "Enroll Certificate" fails. On nodes, I get the following error message: libvirtd[20399]: Unable to import CA certificate list /etc/pki/vdsm/certs/cacert.pem The root cause is the malformed cert: $ cat /etc/pki/vdsm/certs/cacert.pem -----BEGIN CERTIFICATE-----\nMIID XXX That, is the .pem file is just one long line with \n characters instead of real newlines. If I convert the \n to real newlines libvirtd starts but that is not the end solution since other issues surfaces. The malforming happens when the engine copies (via ansible) the CA cert to the node(s). Any ideas what is going on? Thanks, Sakari
