Hello,<div>I want to share some information between a driver domain for a NIC and the hypervisor, for eg, the number of packets transferred etc.</div><div><br></div><div>To do this, I am using the HYPERVISOR_shared_info in the netback driver, within the IDD to store the count of number of packets transferred. I have added some extra fields in the shared_info structure to suit my purpose.</div>

<div>I want to transfer this packet count from netback to the hypervisor. </div><div>As i understand, the HYPERVISOR_shared_info page of a domain is shared as shared_info in the struct domain (defined in sched.h). </div>
<div>
But, the data is not propagating from the netback driver to the hypervisor. Even though the packet count in IDD&#39;s HYPERVISOR_shared_info is increasing, the packet count in domain-&gt;shared_info does not change.</div>

<div>What am i missing here ? or is there a better way to do this ?</div><div><br></div><div>Thanks in advance !<br clear="all"><br>-- <br>--<br>    With Regards ,<br>        Amod Jaltade<br>
