Hi, I suspect this is a timeout in waiting for the VM to boot. In particular I don't see -enable-kvm in the qemu-system-x86_64 options; that flag should be automatically added when /dev/kvm is availale. Could you check (1) whether /dev/kvm is available, and in general if you can expect accelerated KVM to be available, and (2) pass something like --timeout-reboot=600 to autopkgtest-virt-qemu to see if that makes it work? Thanks, Paride
