[PATCH 01/10] vl.c: Do not add isa-parallel if it's not present |
Date: |

Currently the isa-parallel driver is always added by default
regardless of the presence of the actual code in the build, which can
lead to a crash:
qemu-system-i386: unknown type 'isa-parallel'
Aborted (core dumped)
Check for the presence of the QOM class and do not include
isa-parallel by default if it's not found.
