Bug Description

Binary package hint: qemu-kvm

qemu-kvm has a faster method of doing I/O on Linux called Linux AIO. According to my tests and the upstream maintainer (http://news.gmane.org/gmane.comp.emulators.kvm.devel/cutoff=48050) it is faster and should not cause any problems.

It is enabled by configure automatically if libaio-dev is added to the build-depends.
