Hi All, I have made some changes to the functions vboxNetworkCreateXML(), vboxNetworkDefineXML(), vboxNetworkUndefine() and vboxNetworkDestroy() to handle multiple host only interfaces as multiple host only interfaces are supported by VirtualBox 3.0 and greater.

commit 027210861c8434ca8c0e58b90094a9ccdeb7c275 Author: Pritesh Kothari <Pritesh.Kothari(a)Sun.com&gt; Date: Thu Aug 13 14:59:07 2009 +0200 libvirt: Merged vboxNetworkCreateXML() and vboxNetworkDefineXML() and added code to handle multiple hostonly interfaces. diff --git a/src/vbox/vbox_tmpl.c b/src/vbox/vbox_tmpl.c index 32bfb4d..6de277f 100644 --- a/src/vbox/vbox_tmpl.c +++ b/src/vbox/vbox_tmpl.c @@ -35,6 +35,7 @@ #include <dlfcn.h> #include <sys/utsname.h> +#include <stdbool.h> #include "internal.h" @@ -5008,253 +5009,188 @@ static virNetworkPtr vboxNetworkLookupByName(virConnectPtr conn, const char *nam return ret;
