I have an issue with my 4.3 hosted-engine. The /var is full. The directory taking 20G is /var/opt/rh/rh-postgresql10/lib/pgsql/data/base/data/16398 some of those files have size over 1GB. Can they be safely removed? TIA

Glusterfs and vm's
by eevans＠digitaldatatechs.com 09 May '21

09 May '21

I have researched and applied several tweaks to Gluster to improve performance but on the vm side, depending on distribution, you can "tweak" the vm for better performance on Gluster as well; yum install tuned.noarch tuned-utils-systemtap.noarch tuned-utils.noarch tuned-gtk.noarch -y (GTK is for a gui if you have one.) tuned-adm profile virtual-guest Also, you can increase or decrease cache or swappiness on the host to fit your vm's, for workstations or servers. My cache is set to 2048 MB cache and swappiness of 10. Thanks for the help you have given me. Eric This helps RHEL and CentOS machines utilize glusterfs and actually speeds teh vm up. I hope this will help someone. If you want the URL for the article, just ask. Also, you can increase or decrease cache or swappiness to fit your vm's, for workstations or servers.

oVirt virtual machines migration 3.6.3 to 4.4.5
by jean-marie.perron＠viseo.com 07 May '21

07 May '21

Hello, We have a project to migrate from an old oVirt infrastructure (3.6.3) to a new one (4.4.5). The new infrastructure is already in place and we want to migrate the virtual machines. We tried to import the virtual machines via a domain with an NFS mount from the old oVirt (import pre-configured domain). With this domain we only see VM disks and not full virtual machines for import. Is there a way to transfer the virtual machines from the old oVirt to the new one by an NFS mount then import into oVirt Engine or a "copy/paste" virtual machine files then import. Thanks a lot, JMP

libvirt crashes / update missing
by Rik Theys 07 May '21

07 May '21

Hi, On our hosts, we periodically see libvirt crashes as described in https://access.redhat.com/solutions/5694061. https://access.redhat.com/errata/RHSA-2021:1125 (issued April 7) is the advisory that contains a fix for this issue. This bug should be fixed in libvirt 6.6.0-13.2 in the "Advanced Virtualization" repo. When I look at the ovirt-4.4-advanced-virtualization repo on my hosts, it does not (yet) contain this update. Are updates from the Advanced Virtualization repo not automatically rebuild for CentOS 8.3? On a CentOS Stream 8 machine, libvirt is version libvirt-6.0.0-35.module_el8.5.0+746+bbd5d70c.src.rpm. Installing centos-release-advanced-virtualization adds the Advanced Virtualization repo file, which then also brings in the 6.6.0-13 version. When I look at a CentOS 8 stream mirror, for example http://mirror.kinamo.be/centos/8-stream/virt/x86_64/, I do see the virt repos with a newer libvirt, but this is not the repo the centos-release-advanced-virtualization package is using? What is the recommended setup to use to have this bug fix available? Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept. Elektrotechniek (ESAT) Kasteelpark Arenberg 10 bus 2440 - B-3001 Leuven-Heverlee +32(0)16/32.11.07 ---------------------------------------------------------------- <<Any errors in spelling, tact or fact are transmission errors>>

oVirt 4.4.6 is now generally available
by Lev Veyde 07 May '21

07 May '21

The oVirt project is excited to announce the general availability of oVirt 4.4.6 , as of May 4th, 2021. 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, as compared to oVirt 4.3. Important notes before you install / upgrade Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJ… ) Rebase on CentOS Stream Starting with oVirt 4.4.6 both oVirt Node and oVirt Engine Appliance are based on CentOS Stream. You can still install oVirt 4.4.6 on Red Hat Enterprise Linux 8.3, CentOS Linux 8.3 or equivalent but in order to use cluster level 4.6 you’ll have to wait for 8.4 to be available. Please note that existing oVirt Nodes updating to 4.4.6 will automatically be based on CentOS Stream. 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>. What’s new in oVirt 4.4.6 Release? This update is the sixth in a series of stabilization updates to the 4.4 series. This release is available now on x86_64 architecture for: - Red Hat Enterprise Linux 8.3 - CentOS Linux (or similar) 8.3 - CentOS Stream 8 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: - Red Hat Enterprise Linux 8.3 - CentOS Linux (or similar) 8.3 - oVirt Node NG (based on CentOS Stream 8) - CentOS Stream oVirt Node and Appliance have been updated, including: - oVirt 4.4.6: https://www.ovirt.org/release/4.4.6/ - CentOS Stream 8 - Ansible 2.9.20: https://github.com/ansible/ansible/blob/stable-2.9/changelogs/CHANGELOG-v2.… - Advanced Virtualization 8.4 See the release notes [1] for installation instructions and a list of new features and bugs fixed.
