<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Calibri","sans-serif";color:black">I’m curious about how people deal with failures of compute nodes, as in total failure when the box is gone for good. (Mainly care about KVM HV, but also interested
in more general cases as well.)<o:p></o:p></span></p>

it, Nova will still believe VMs are running, and really has no way to know anything has changed (other than the nova-compute instance has dropped off.)<o:p></o:p></span></p>
