&gt; Hello,<br>
&gt; Is there a way to determine state of the qemu/kvm guest OS<br>
&gt; (rebooting/working/hung etc) from the host. I&#39;m not referring to the<br>
&gt; qemu domain state itself<br>
&gt;<br>
<br>
</div>Well, I don&#39;t quite understand how would you do this on real host other<br>
than looking at its screen.<br>
Anyway, libvirt allows mgmt applications to peek into guest memory and<br>
dump it. This is how virt-dmesg works [1]. So maybe it would be handful<br>
example for you.<br>
