Bug Description

Counterpart to https://gitlab.com/libvirt/libvirt/-/issues/515

/sys/devices/system/node/*/cpumap r,

Those changes are usually safe, there is sadly no abstraction for libnuma.
Steps:
1. propose the change as a patch upstream
2. add it to the related Ubuntu releases

This is in qemu 7.2 as reported:

$ git tag --contains e6816

Therefore this is for lunar+mantic
