Canonical is offering a new approach to providing up to date virtual machine support on Ubuntu long-term support (LTS) releases. Ijlal Loutfi writes: "Before Ubuntu 26.04 LTS, Ubuntu already had a Hardware Enablement model for the kernel. This is a core part of confidential computing enablement: it includes KVM support, memory-management changes, CPU feature enablement, and the low-level interfaces that confidential virtual machines depend on. But the kernel is only one layer. If the kernel moves forwards while QEMU, libvirt or firmware remain too far behind, users can still be blocked from using new virtualization capabilities end to end."Canonical will be offering optional upgrades to these virtualization tools for LTS releases, providing a way for virtual machine users to gain access to new features without needing to upgrade to a new version of Ubuntu. |
