I have always hated flavors and so do many of my users.

This while apparently reasonable is BS (at least in private cloud space). What users request and what they actualy use are wildly divergent. *IF* usage of claimed resorces were at or near optimal then this might be true . But if people are claiming 32G of ram because that how much you assigned to a 16 vCPU instance type but really just need 16 threads with 2G or 4G then you packing still sucks. I'm mostly bound on memory so I mostly have my users select on that basis and over provide and over provision CPU since that can be effectively shared between VMs where memory needs to be dedicated (well mostly) I'm sure I've ranted abotu this before but as you see from other responses we seem to be in the minority position so mostly I rant at the walls while my office mates look on perplexed (actually they're pretty used to it by now and ignore me :) ) -Jon _______________________________________________ OpenStack-operators mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
