QEMU commands config notes:

for centos7, use settings below:
QEMU_IMG_EXEC = '/usr/bin/qemu-img'
QEMU_KVM_EXEC = '/usr/libexec/qemu-kvm'

for fedora, you can use the following settings
QEMU_IMG_EXEC = '/bin/qemu-img'
QEMU_KVM_EXEC = '/bin/qemu-kvm'

for ubuntu, please help us to figure out the settings
