<br>This may be interesting, but totally off topic :)

<br>> Which mail are you referring to?

<br>This one: http://lists.openstack.org/pipermail/openstack/2013-November/002623.html
<br>subject: "Instances fail during/after networking"

<br>> and what do you mean by “crazy”? Performance-wise or did you have some bugs

<br>
<br>nova-network is spinning at 80-90% of cpu for minutes, giving IP
<br>addresses only after a few *minutes*, so that the creation of the VM
<br>goes in timeout and thus is failing.
<br>Similarly when deleting a VM, it takes ages and sometimes I have to
<br>terminate them twice in order to have them killed.
