Sure, but do you know any other distro which would use another stupid
non-standard location and name for QEMU binaries? I hope they would all
use upstream names and locations, i.e., /usr/bin/qemu-system-$ARCH or
/usr/libexec/qemu-kvm if they are derived from RHEL. If there are other
options, I guess we should handle them.
Currently, we probe for /usr/libexec/qemu-kvm, qemu-kvm, and kvm in
virQEMUCapsInitGuest and we could easily extend this list if needed.
