[Qemu-devel] [Bug 722311] [NEW] Segmentation fault if started without -enable-kvm parameter

[Bug Reporter]

Public bug reported:

I start qemu (Linux) from the same USB memory stick on several
computers. Up to and including qemu 0.12.5, I could use or not use
qemu's "-enable-kvm" command line parameter as appropriate for the
hardware, and qemu would run. In contrast, qemu 0.13.0 and 0.14.0
segfault if started without "-enable-kvm". I get a black window
appearing for fractions of a second, disappearing immediately, and then
the error message "Segmentation fault".

Hardware: Pentium 4, and Core 2 Duo.
Command line: either "qemu" or "qemu -enable-kvm" (after manually loading the 
kvm-intel module on the Core 2 Duo).
Reproducible: always.

** Affects: qemu
     Importance: Undecided
         Status: New
