It turns out that mesa uses llvm's getHostCPUName(), and qemu i386 by default (correctly) reports itself as pentium2, which is assumed non-sse2. gnome-shell uses a mesa feature that requires sse2, so it fails at startup on qemu i386. On llvm trunk they've implemented getCPUTargetFeatures(), which can be used to check for specific cpu features like sse2, and that is the long term solution to the problem: https://llvm.org/bugs/show_bug.cgi?id=23201 In the meantime, the problem can be worked around by using a non-default qemu cpu options. Some examples: $ qemu -cpu pentium3 test.img $ kvm -cpu host test.img Since there workarounds are straightforward I am reducing the severity.
