Spelling error: "Nombat" should be "Numbat". Ubuntu 24.04's codename is "Noble Numbat", not "Noble Nombat".

CPU configuration mismatch: vcpu is set to 1, but the CPU topology specifies 4 virtual CPUs (1 socket × 2 cores × 2 threads = 4). Either change vcpu to 4 or adjust the topology to match 1 vCPU (e.g., <topology sockets='1' cores='1' threads='1'/>). For a generic configuration, it's typically better to set vcpu to 1 and remove the topology element, allowing it to be configured dynamically.

Suggested change

<topology sockets='1' cores='2' threads='2'/>

@wenqiange Copilot warned vcpu is set to 1, but in cpu topology is 1-2-2. I think the vcpu line can be removed. Please try and see if it works.
