Comment 7 for bug 2015355

I have verified the fix using util-linux 2.34-0.1ubuntu9.4 from focal-proposed:

$ qemu-img create -f qcow2 test.img 20G
Formatting 'test.img', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=21474836480 lazy_refcounts=off refcount_bits=16
$ qemu-system-x86_64 -enable-kvm -m 4096 -name test -drive file=test.img,format=qcow2 -net nic,model=virtio -net user,hostfwd=tcp::7022-:22 -vga virtio -cdrom ~/downloads/ubuntu-20.04.6-desktop-amd64.iso
qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2]

Inside the VM:
