&gt; Will Intel or AMD be able to fix this in microcode (by making it do the right thing if an external interrupt or NMI arrives)?<p>What I want to know is: does this affect other hypervisors as well? If this is a bug related to the CPU, why haven&#x27;t we heard from KVM, VMWare, etc about it?<p>I can&#x27;t believe Xen basically just said &quot;run PVM or get pwned&quot;
