Whole Host Allocation
Allow a tenant to allocate all of the capacity of a host for their exclusive use. The host remains part of the Nova configuration, i.e. this is different from bare metal provisioning in that the tenant is not getting access to the Host OS - just a dedicated pool of compute capacity. This gives the tenant guaranteed isolation for their instances, at the premium of paying for a whole host.
The blueprint achieve this by building on the existing host aggregates and filter scheduler.
Extending this further in the future could form the basis of hosted private clouds – i.e. schematics of having a private could without the operational overhead.
In effect what we are doing is to make host aggregates a user facing feature (with appropriate controls), and providing an anonymous host allocation mechanism

[jpretorius 2013/12/13]
Once the base code is done, please add something to Horizon to expose this via the UI. My thinking is:
- During instance creation, allow the deployment to a pcloud that the end-user has access to
- When listing instances, show the pclouds that instances are hosted in
- When viewing the instance details, show the pcloud that an instance is hosted in
Also, please test that the scheduler allows an end-user to migrate/
