I'm not very familiar with libvirt, which changes are needed for query, this one: https://git.codelinaro.org/linaro/dcap/qemu/-/commit/250732e03bf0bd2e2a9058358707baf51d0193cb#68c067b8d3c460fb3331256759e405f48df64c73 ? The problem for upstreaming QEMU VMM patches is that the whole series depends on the updated KVM API, so until that gets merged in Linux I can't get the QEMU patches merged https://git.codelinaro.org/linaro/dcap/qemu/-/commit/bb044aeb5bf888f193b1def0a4d03de2ff8389ac https://lore.kernel.org/linux-arm-kernel/20241004152804.72508-1-steven.price@arm.com/ And without the KVM API we can't allow users to create a rme-guest object, since it wouldn't be functional. Thanks, Jean
