Recently, my works were focused on network emulator with virtualization.

In the Fedora 10 distro, qemu is installed without acceleration by default.
Neither it is in the package repo; so, we have to add kqemu (kmod-kqemu) on our own.

1. First, we assume the qemu-* were already installed.
2. Then, add a new repo from RPM Fusion

# rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm

3. After that, now you can install kqemu by yum

# yum install kqemu
