This is a bug in guest. hers's the disassembly of the code in question: 00000000 <.data>: 0: 85 ed test %ebp,%ebp 2: be 4a 2d a8 f2 mov $0xf2a82d4a,%esi 7: 92 xchg %eax,%edx 8: d9 bb 21 7e 85 aa fnstcw -0x557a81df(%ebx) e: 53 push %ebx f: 6b 60 01 6d imul $0x6d,0x1(%eax),%esp 13: 4d dec %ebp 14: da 9d 39 b2 0e 7e ficompl 0x7e0eb239(%ebp) <=== here 1a: 52 push %edx 1b: 3d 0f d0 29 d5 cmp $0xd529d00f,%eax 20: e6 0c out %al,$0xc 22: be f9 76 31 43 mov $0x433176f9,%esi 27: 4f dec %edi 28: 86 c2 xchg %al,%dl 2a: 4e dec %esi 2b: be ba c5 34 52 mov $0x5234c5ba,%esi 30: 9b fwait 31: c4 .byte 0xc4 It is a floating-point/integer comparison instruction. The instruction sequence smells like your guest code jumped to some random junk. How far in the boot process it happens? Is it in lilo or in the kernel? How much memory did you assign to the guest? Thanks, /mjt
