Subject: Emulation failure

Message-ID: <1376874854.25492.10.camel@localhost> (raw)
Hi,
I got this error with qem-kvm-0.15.1 on kernel 3.1.0-1.2-desktop
(OpenSUSE 12.1). I know I should rerun it with latest kernel/qemu but I
hope maybe this rings a bell or something, because it'll take some time
for me to prepare new kernel.
KVM internal error. Suberror: 1
emulation failure

The disassembled code is
0x1dd10: push %rbx
0x1dd11: mov $0x6e,%eax
0x1dd16: mov %rdi,%rbx
0x1dd19: sub $0x20,%rsp
0x1dd1d: test %rdi,%rdi
0x1dd20: je 0xb1dd92
0x1dd22: mov 0x4bf1e0(%rip),%eax
0x1dd28: cmp $0xffffffff,%eax
0x1dd2b: je 0xb1ddd0
0x1dd31: test %eax,%eax
0x1dd33: jne 0xb1dd92
0x1dd35: mov 0xe1f55c(%rip),%rax
0x1dd3c: cmpq $0x0,0xf0(%rax)
0x1dd44: fildll 0xf0(%rax)
0x1dd4a: js 0xb1ddf0
0x1dd50: mov 0xe1f54a(%rip),%eax
0x1dd56: mov %rax,-0x80(%rsp)
0x1dd5b: fildll -0x80(%rsp)
0x1dd5f: fmulp %st,%st(1)
Not sure if it helps but rax after 0xb1dd35 contains the pointer to
mmap'd memory of /dev/hpet
