Avi,
Running this command:
qemu-system-x86_64 -net nic,model=rtl8139 -net user -hda $1 -no-acpi
-usb -cpu 486,-fpu &
I get a seg fault:
qemu-system-x86[15419]: segfault at c ip 0000000000458b95 sp
0000000041d9df90 error 4 in qemu-system-x86_64[400000+208000]
I am running kvm-87 centos 5.3 x86_64.
Add -no-kvm-irqchip. A 486 doesn't have a local APIC, which the code
expects.
Running with this line:
qemu-system-x86_64 -net nic,model=rtl8139 -net user -hda $1 -no-acpi
-usb -cpu 486,-fpu -no-kvm-irqchip &
My /proc/cpuinfo shows the follow:

cpu family : 4
model : 0
model name : 04/00
stepping : 0
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : no
cpuid level : 0
wp : yes
flags :
bogomips : 2965.50
clflush size : 32
power management:
Notice FPU indicates yes and I requested -fpu on the command line.
I think it detects the host fpu as a 487 coprocessor. Anything in dmesg
about it? Note there's no fpu in the flags: line.
That's a kvm kernel bug.
also is this a 486 as it says AMD?
You can override it if you like, -cpu 486,vendor=AuthenticAMD (I think).
