Title:
[feature request] add flag to treat warnings as errors
Status in QEMU:
New
Bug description:
Since booting could potentially take a lot of time and warnings are
likely to indicate that something is wrong, it would be useful to have
a command line flag which would abort the boot if there are any
warnings.
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 created
(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).
