Only send irqs to ioapic in case we have one. Fixes qemu segfault. Linux kernel still needs explicit noapic noacpi on the kernel cmd line to boot. Do we need a different bios for isapc? Or a fw_cfg knob to turn off all the modern stuff (apic, acpi, smp, ...)? Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> --- hw/pc.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-)
