but everything above a minute could become critical for large orgs<br>
relying on the ability to spawn vms at any given time.<br>
<br>
or imagine critical HA vms running on ovirt:<br>
you can't migrate them, when the engine is not running.<br>
you might not even want a downtime of a single second for them, that's<br>
why you implemented things like live migration in the first place.<br>
<br>
the bottom line is:<br>
if you manage critical infrastructure, the tools to manage<br>
this infrastructure have to be as reliable as the infrastructure itself.<br>
