Ever since commitc5a00350the libxl parser invokes the emulator to probe which device model to use. Commitb90c4b5introduced a workaround that used a stable path which was very likely to result in the answer matching the default. However the test is still affected by the host state and the binary gets invoked if present. Mock the libxlDomainGetEmulatorType function to stop wasting CPU cycles every time a 'make check' is run on a system with xen installed. For example xlconfigtest gets faster by 90 % Signed-off-by: Ján Tomko <jtomko@redhat.com> Fixes:b90c4b5f50Reviewed-by: Jim Fehlig <jfehlig@suse.com>
