<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">IMHO, this seems fit better of the availability since location is more about availability like power supply, network switch availability etc.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Or, what’s the boundary of host aggregate and availability zone? Seems host aggregate is so magic that it can cover every requirement to separate/group the host,
but also, because it’s so magic, it’s sure to require some other mechanism to help it to do the real separation/group.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Maybe the answer is hiding in plain sight: host aggregates. This is a concept we already have, and it allows identification of arbitrary groupings for arbitrary
purposes.</span><span lang="EN-US"><o:p></o:p></span></p>
