On a machine where no QEMU binary is installed, we end up logging libvirtd: Cannot check QEMU binary /usr/libexec/qemu-kvm: No such file or directory which is not very useful in general, and downright misleading in the case of operating systems that are not derived from RHEL. This is a consequence of treating that specific path in a different way from all other possible QEMU binary paths, and specifically of not checking whether the file actually exists but sort of assuming that it must do if we haven't found another QEMU binary earlier. Address the issue by trying this path out in virQEMUCapsFindBinaryForArch(), along with all the other possible ones, and making sure it exists before returning it.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
