An '=' went missing here. Assuming it was unitentional, and since it was
breaking the build with --enable-compile-warnings=error, I pushed this:
diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c
index 5f1d6b5..ab6bec8 100644

- if (qemuDomainObjEndJob(vm) = 0) {
+ if (qemuDomainObjEndJob(vm) == 0) {
vm = NULL;
goto cleanup;
}
