Subject: [PATCH] qemu: Upstream regression of -stdio serial option.
|
|
|
|
Best explained by the comment in the code:
|
|
|
|
/* Newer versions of qemu (from around 2009/12) changed the
|
|
* behaviour of monitors so that an implicit '-monitor stdio' is
|
|
* assumed if we are in -nographic mode and there is no other
|
|
* -monitor option. Only a single stdio device is allowed, so
|
|
* this broke the '-serial stdio' option. There is a new flag
|
|
* called -nodefaults which gets rid of all this default crud, so
|
|
* let's use that to avoid this and any future surprises.
|
|
