An example might be network configuration. The following output most likely indicates that there is something the user has to fix before starting and being able to use the guest os. Warning: hub port hub0port0 has no peer Warning: vlan 0 with no nics Warning: netdev hub0port0 has no peer Warning: requested NIC (anonymous, model vitrio-net-device) was not creat= ed (not supported by this machine?) Ideally, there would be an option the user could pass which would cause qemu to print these warnings then exit, rather than boot the kernel. Alternatively, or additionally, a dry run option would be helpful for the same purpose: making sure qemu get to the booting the kernel stage with everything in working order so that you do not have to wait for the kernel to boot and then shut down while debugging things like networking (things which can be debugged (at least partially) without booting, or trying to boot, the guest os).
