Re: [Libvir] [PATCH] modular compilation of xen/qemu/test

The following patch adds 3 configure options to turn on or off the support for Xen, QEMU/KVM and the test driver, as the output of configure --help shows: ... --with-xen add XEN support (on) --with-qemu add QEMU/KVM support (on) --with-test add test driver support (on) ... It uses compile time flags, is not really intrusive, it just pointed out a few strangeness, one of which was fixed (a Xen include) and the remaining ones are: - xml.c doesn't depend on Xen except for virDomainXMLDevID calling xenStoreDomainGetNetworkID() - libvirt.c still calls xenDaemonDomainLookupByName_ids from virDomainGetUUID() , I'm not sure if this can be avoided In the tests directory, sexpr2xmltest.c and xmconfigtest.c still depends on code in xen specific modules, trying to add them without xen being present was more complex than the value it may add (it also makes the patch smaller to cut at the module level). Plan to commit this before the release, unless this raises a problem,
