  Hi,

I'm not sure what the consensus is for cases like this where QEMU's correct
to warn about dodgy device access but a popular operating system(tm) does
them anyway. Suppressing the warning seems a bit more user-friendly to
the average QEMU user...

It is also a (minor) DoS, the guest can flood the logs on the host. Stuff like that should not be logged by default, having an option to enable such messages for trouble-shotting purposes is fine.

Patch queued up, thanks.

cheers,
  Gerd
