<div>*likely these problems would require some managed migration "thing" that would temporarily open the network access, issue temporary auth keys and the initiate the migration between the 2 hypervisors. Is this in your scope, to make this thing??<div class="im">

<div>Hi,</div>
<div><br>
</div>
<div>I think it's a good idea, can u describe more what would be different, would there be a new auth and live migration mechanism? </div>
<div><br>
</div>
<div>I think one of the problems at least yahoo has is that live migration requires all ssh keys to be on all hypervisors since hypervisors (libvirtd) open up the connection to the hypervisor to be migrated to. This is obviously bad, as any hacker if they can
get out of a vm now can start issuing these migration requests. Also at yahoo we don't allow hypervisors to communicate openly to each other, this is protected at the network level. Would u be working on solutions to these problems (likely involving <br>

Is there any write up of what u want to do or is that not defined yet?<br>
<br>
If u can write up some information I think that would help others provide feedback as well as help everyone (including yourself) see the goal too be accomplished. It's hard to tell what the desired outcome is otherwise, secure vm migration could mean a lot
of things :)<br>
