So, if my blame-fu isn't flawed, then I don't think that vhostuser ever reported a warning during machine startup, have a look at commits 4a74ccdb92f and 0bce012d7f0 respectively - there always was a goto cleanup statement. > > Signed-off-by: Michal Privoznik <mprivozn@xxxxxxxxxx> > --- > src/qemu/qemu_command.c | 6 ++++++ > 1 file changed, 6 insertions(+) > > diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c > index 6e3ff67660..489e8bc689 100644 > --- a/src/qemu/qemu_command.c > +++ b/src/qemu/qemu_command.c > @@ -8246,6 +8246,12 @@ qemuBuildVhostuserCommandLine(virQEMUDriverPtr driver, > goto cleanup; > } > > + if (virDomainNetGetActualBandwidth(net)) { > + VIR_WARN("setting bandwidth on interfaces of " > + "type '%s' is not implemented yet", > + virDomainNetTypeToString(VIR_DOMAIN_NET_TYPE_VHOSTUSER)); > + } > + We already do this kind of checking on line 8593 in the same source file. It's just because of the goto cleanup jump after calling qemuBuildVhostuserCommandLine that causes the logic to never reach the condition (Not to mention the code is a mess). I'd suggest moving the already existing check to the top of the qemuBuildInterfaceCommandLine function instead of duplicating the code.
