<div dir="ltr"><div><div>Hello Joe,<br></div>I would have recommended to have a look at Blazar but since you already did... Maybe your users could mimic how Blazar accomplishes resource reservation? IIUC Blazar will spawn the reserved instances but in shelved mode [1] so they won't consume any cloud resources but they will still be accounted by the resource tracker. When the lease starts, Blazar will unshelve the instances.<br></div><div>HTH<br>Simon<br>[1] <a href="https://wiki.openstack.org/wiki/Blazar#Virtual_instance_reservation">https://wiki.openstack.org/wiki/Blazar#Virtual_instance_reservation</a><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Oct 23, 2014 at 5:20 PM, Joe Topjian <span dir="ltr"><<a href="mailto:joe@topjian.net" target="_blank">joe@topjian.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hello,<div><br></div><div>I'm sure some of you have run into this situation before and I'm wondering how you've dealt with it:</div><div><br></div><div>A user requests that they must have access to a certain amount of resources at all times.
