Disable or redirect femu debug outputs about femu HOT 4 CLOSED

You can comment out the corresponding printf() in hw/block/ssd/ftl.c Line 305 and recompile FEMU to get rid of it.

Thanks for your quick reply!
Unfortunately this is not the only one. For example it is observed that printf at hw/block/ssd/ftl_gc_manager.c Line 155 will also print to terminal.
There are many other printf calls in source files in hw/block/ssd. Is it that I should comment out all of them?
Thank you in advance.

Many printf()s are not in the hot path (for debugging purpose) and they're not being triggered very often. Depending on what you want to achieve, you can comment out all of them.

You can also simply redirect all the output into a log file, add "> log 2>&1" at the end of qemu command line in the VM script.
