Hi All, This is a V2 of Dario's old patches adding support for specifying the virtual CPU address size in bits https://listman.redhat.com/archives/libvir-list/2020-October/210901.html I've rebased those patches to latest master and tweaked them a bit. E.g. I removed the qemucaps code since phys-bits and host-phys-bits have been around before the minimum qemu version supported by libvirt. I also added patches to expose the number of host address bits and ensure ABI stability as requested in the old review comments.
