[Openstack-devel] Volatile images and/or hybrid cloud use cases

[Daniel Pocock]

I'm just wondering if anyone can comment on the following two topics:


a) volatile images - e.g. development servers where new packages are
installed every few days and where the entire system state must be
preserved on every reboot.  Can the whole image concept be bypassed and
the entire instance runs from persistent storage?


b) hybrid deployments - e.g. if somebody already has 5 physical servers
running VMs with a vanilla Xen hypervisor, can they add Nova to those
servers and run some OpenStack managed VM instances alongside the
standalone images?  Or do they need to move all the vanilla VMs onto 3
servers and then just run Nova on the other 2?
