** Description changed: [ Impact ] - Libvirt is missing support for Intel Granite Rapids processors. This should be fixed as a part of hardware enablement. [ Test Plan ] - To test the fix, an Intel Granite Rapids system must be used. Install libvirt with: $ sudo apt install qemu-kvm libvirt-daemon-system Then check the processor identification with virsh: $ virsh capabilities - It should respond with the model SapphireRapids in the format: + It should respond with the model GraniteRapids in the format: <capabilities> - <host> - <uuid>XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX</uuid> - <cpu> - <arch>x86_64</arch> - <model>GraniteRapids</model> - <vendor>Intel</vendor> + <host> + <uuid>XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX</uuid> + <cpu> + <arch>x86_64</arch> + <model>GraniteRapids</model> + <vendor>Intel</vendor> ... - [ Where problems could occur ] Since the change comes in as one commit and well isolated from the rest of the libvirt source tree. I don't expect places where problems could occur because of the intruduction of this change. [ Other Info ] The issue is fixed through a patch that adds necessary CPU features and definitions. For the majority of use cases libvirt, is used with Qemu backend (other backends are KVM and LXC), this libvirt capability requires Qemu to have the same capability. The granite rapids support has been introduced to Qemu upstream in the commit: 6d5e9694e : target/i386: Add new CPU model GraniteRapids And this change has been released in Qemu upstream v8.1.0 - and is available in Oracular (1:9.0.2+ds-4ubuntu5) and Noble + and is available in Oracular (1:9.0.2+ds-4ubuntu5) and Noble (1:8.2.2+ds-0ubuntu1.3) - ------------- [Description] Add Granite Rapids CPU model feature map to libvirt, depends on QEMU support.
