Yuck, this fails to compile with Clang:


   ../target/i386/kvm/kvm.c:470:25: error: field 'info' with variable sized
type 'struct kvm_msrs' not at the end of a struct or class is a GNU
extension [-Werror,-Wgnu-variable-sized-type-not-at-end]
          struct kvm_msrs info;

Anybody any ideas how to fix this best? Simply disable the compiler warning
in QEMU?

There's already a patchset on list that does that:

Perfect, that's exactly what I need, thanks! I'll add those patches to my queue.
