what is the defferences between /usr/libexec/qemu-kvm and /usr/bin/qemu-system-x86_64? my OS is centos6.2, qemu-kvm is from a rpm package, while qemu-system-x86_64 is builded manually from source code. 1. if i can recognize they are the same thing? 2. for centos distro, how to build a qemu rpm from source code? it seems there is no qemu.spec file
thanks
