The code of the upgrade tester basically spawns a kvm instance in the background with a port redirect from localhost:54322 to tcp:22 in the VM, then wait for that port to allow for a ssh connection before continuing the upgrade testing. In the past (Oneiric), all worked well but since Precise, we now get qemu exitting with -11 at every single test :( A quick reproducer is: - start a VM that has openssh-server installed with: -net user,hostfwd=tcp::54322-:22 - immediately start "ssh -p 54322 127.0.0.1" before the VM starts booting (BIOS/GRUB state) Then wait for sshd to start in the VM and qemu will exit with -11.
