If we break it down, I'm not sure a VM will be able to boot with no volume/root disk from an image though?
I guess you could have the root VM drive all in RAM, but I don't think that Openstack understands that. [...]
Well, the question seemed to be primarily about booting the underlying hardware (compute nodes) over the network. This is actually pretty commonly done, at least for provisioning, but could certainly also be used to get enough of a kernel running to find the root disk over iSCSI or whatever. As for the virtual machines (server instances), you can boot-from-volume and use any sort of remote storage Cinder supports, right? -- Jeremy Stanley
