Comment 4 for bug 1891203

Maybe what I found is a valid issue present in all qemu 4.2 builds we have, but not related to your initial struggle to get bionic-ussuri to run?

Could you please throw that patch on top of your B-ussuri builds and see if then everything magically works - or if we only fixed this issue, but not the "other" one blocking your system from recognizing aarch64 as valid arch to run KVM on.
