# Commit 473a49460db0a90bfda046b8f3662b49f94098eb (qemu) makes "no_floppy = 0"
# for pc-q35-2.3 hardware, and OS X doesn't like this (it hangs at "Waiting for
# DSMOS" message). Hence, we switch to pc-q35-2.4 hardware.
#
# Network device "-device e1000-82545em" can be replaced with "-device vmxnet3"
# for possibly better performance.
