Reproduced with qemu-kvm-0.12.1.2-2.295.el6.x86_64:

[root@localhost ~]# /usr/libexec/qemu-kvm -serial unix:/tmp/u1,server,nowait -serial unix:/tmp/u2,server,nowait -serial unix:/tmp/u3,server,nowait
isa irq 4 already assigned

Verified on qemu-kvm-0.12.1.2-2.295.el6_3.1.x86_64:

[root@localhost ~]# /usr/libexec/qemu-kvm -serial unix:/tmp/u1,server,nowait -serial unix:/tmp/u2,server,nowait -serial unix:/tmp/u3,server,nowait -serial unix:/tmp/u4,server,nowait
VNC server running on `::1:5900'
