Upgrade Path: Ubuntu 22.04 LTS → Ubuntu 24.04 LTS Summary of Work
To ensure the continued security and performance of our virtualization infrastructure, we are upgrading the KVM345 hostnode to the latest Long Term Support (LTS) version. This maintenance brings critical updates to the Linux Kernel (5.15→6.8), QEMU, and Libvirt, providing better memory management and system stability. Impact on Virtual Machines
During this maintenance window, the hostnode will require a full system reboot to initialize the new kernel and virtualization stack.
State Saving: Before the final restart, we will attempt to "Save to Disk" (Suspend) all running Virtual Machines. This captures the current RAM state so the VM does not have to perform a cold boot.
Resuming: Once the hostnode is back online, we will automatically attempt to resume all saved VMs.
Potential Downtime: Clients should expect a temporary loss of connectivity for the duration of the host reboot (approximately 10–15 minutes).
Expected Timeline
Preparation: Final backups of host configurations in progress today. This will not affect any systems.
OS Upgrade: In-place upgrade of system packages started tomorrow.
Final Reboot: VMs are saved, the host restarts, and VMs are resumed.
The total time for the upgrade is expected to take 1 hour, the shutdown, resume and reboot time is expected to take less than 15 minutes.
