Hi, when I read following link, http://wiki.xen.org/xenwiki/XenIntro , then I browsed some Xen 3.1 code. A question puzzles me. As we know "The physical xenstore resides in one file: /var/lib/xenstored/tdb. " , but drives(frontend/backend) visit Xenstore by Xenbus. The data structure manipulated by Xenbus is xenstore_domain_interface, not tdb. while tdb file is visited by Xenstored daemon. I cann't figure out the relationship between tdb and xenstore_domain_interface. For example, if Xenbus sends a XS_DIRECTORY query message , where does the reply message come from? Thanks in advance! _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
