<p>Hi all,</p>
<p>At this moment, Magnum is still using Fedora Atomic 27 as the
default image in devstack. But you can definitely use Fedora
Atomic 29 and it works fine. But you may run into a performance
issue when booting Fedora Atomic 29 if your compute host doesn't
have enough entropy. There are two steps you need for that case:</p>
<pre class="moz-quote-pre" wrap="">1. Adding property hw_rng_model='virtio' to Fedora Atomic 29 image
2. Adding property hw_rng:allowed='True' to flavor, and we also need <span class="pl-s"><span class="pl-pds"></span>hw_rng:rate_bytes=4096 and </span><span class="pl-s">hw_rng:rate_period=1 to get a reasonable rate limit to avoid the VM drain the hypervisor.</span></pre>
<p>We are working on a patch for Magnum devstack to support FA29 out
of box. Meanwhile, we're starting to test Fedora CoreOS 30. Please
popup in #openstack-containers channel if you have any question.
Cheers.</p>
