[Xen-devel] xenstore -- read UUID

[dinesh chandrasekaran <dinesh_chan8@xxxxxxxxxxx>]

Hi All,

     Im trying to read the UUID of a domain-U from domain-0 using the following code from inside say xen/common/memory.c.

The include file <xs.h> is present both in /usr/include and tools/xenstore/xs.h

#include <xs.h>    
static int get_domain_uuid(unsigned int domain_id) {
        struct xs_handle *xs;
        xs_transaction_t t;
        char *path;
        unsigned int *len;
        void *uuid;
        xs = xs_daemon_open();
        if (xs == NULL)
                return 1;
        path = xs_get_domain_path(xs, domain_id);
        if (path == NULL)
                return 1;
        strcat (path, '/uuid');
        len = strlen(path) + 1;
        uuid = xs_read(xs, t, path, len);
        printf('%lx \n', (char) (*uuid));
        xs_daemon_close(xs);
        free(path);
        return 0;
}

when compiled throws an error ( xs.h - no such file or directory).

How to access xenstore and read the doamin UUID from dom-0 specifically from inside xen/common/memory.c?

regards,
Dinesh C
