Package: autopkgtest Version: 5.6 Severity: normal It looks like the way autopkgtest calls qemu is suboptimal:

I do not get that warning when launching qemu by hand, for example this works flawlessly: qemu-system-x86_64 -enable-kvm -snapshot -m 1G,slots=3,maxmem=4G /var/lib/libvirt/images/debian9-amd64-autopkgtest.qcow2 Maybe qemu needs to be launched with `-enable-kvm`?
