I've symbol files and debugging files of the kvm binary.
Accessed address: c050 Address of the instruction that segfaulted: 00007fcfc3465eac Base memory address where kvm code was mmapped: 7fcfc3223000 Length of mmap: 3ba000 Try the following: $ printf '%x' $((0x7fcfc3465eac - 0x7fcfc3223000)) 242eac $ addr2line -e path/to/qemu-kvm-symbols -f 242eac I also suggest posting about 10 lines before/after 0x242eac from the objdump -d path/to/kvm output. That way we can sanity check that the instruction accesses memory and see what the surrounding instructions are doing. Stefan
