All, Starting today, we will be going through all of our hypervisor nodes and upgrading them to AlmaLinux 9 from AlmaLinux 8. After the hypervisors are upgraded, we will be also upgrading the controller node which will require around 30-45 minutes of downtime for services related to that. I will send an email out when I plan to do the controller upgrade.
Due to the lack of support for live migration with the current version of l ibvirt on the nodes, we will need to do a "cold" migration of each VM. This means we will gracefully shutdown the VM and move it to another node. I am hoping the newer libvirt will finally provide support for live migration. I will send out periodic updates if needed. I expect this to last a couple of weeks between all the various nodes we need to do this on. If you have any questions, please let me know. -- Lance Albertson Director Oregon State University | Open Source Lab
