While it's true that our virCommand subsystem is happy with non-absolute paths, the dnsmasq capability code is not. It stores the path to dnsmasq within and makes it accessible via dnsmasqCapsGetBinaryPath(). While strictly speaking no caller necessarily needs canonicalized path, let's find dnsmasq once and cache the result. Therefore, when constructing the capabilities structure look up the binary path. If DNSMASQ already contains an absolute path then virFindFileInPath() will simply return a copy. With this code in place, the virFileIsExecutable() check can be removed from dnsmasqCapsRefreshInternal() because virFindFileInPath() already made sure the binary is executable. But introducing virFindFileInPath() means we have to mock it in test suite because dnsmasqCaps are created in networkxml2conftest. Moreover, we don't need to check for dnsmasq in configure.

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.
