Currently, qemucapsprobe fails when libvirt is not already installed on the system: $ ./tests/qemucapsprobe /path/to/qemu-system-ppc64 >/dev/null I/O warning : failed to load external entity "/usr/share/libvirt/cpu_map/index.xml" 2020-05-06 09:49:59.136+0000: 269822: info : libvirt version: 6.4.0 2020-05-06 09:49:59.136+0000: 269822: info : hostname: [...] 2020-05-06 09:49:59.136+0000: 269822: warning : virQEMUCapsLogProbeFailure:5127 : Failed to probe capabilities for /path/to/qemu-system-ppc64: XML error: failed to parse xml document '/usr/share/libvirt/cpu_map/index.xml' It would be great if the tool could work entirely out of the build directory, and this patch achieves just that.
