So, this has already been merged and it's definitely an improvement over the existing situation (thanks to both you and Michal, by the way!), but I was wondering whether removing the hardware check altogether is a good idea. There is a difference between KVM not being built properly / shipped / loaded and the host not supporting hardware virtualization at all. We capture that difference on x86 and s390, but not on aarch64 and ppc64. Is figuring out whether hardware virtualization support is present just not feasible on aarch64, eg. because each reports the information in a different way, or because the information is not exposed to userspace at all? -- Andrea Bolognani Software Engineer - Virtualization Team -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
