Description of problem:
Customers expect to be able to move their virtual machines around, without changing their state, to:
- Balance load across their environment for either maximum performance or maximum consolidation
- Prepare for changes to the environment
- React to (unforeseen) changes to the environment
- etc.
Our enterprise virtualization platform and indeed our cloud management software supports this, but we do not configure it out of the box instead leaving users to follow an error prone manual procedure.
Director needs to deploy environments that, depending on the storage choices made support either:
Live shared storage migration; or
Live block migration
Without any post-deployment changes being required of the user. The deployed environments should also support so called cold options for moving workloads such as migrate, resize, etc. without additional configuration changes.
The deployed environments should follow the recommendations of the RHEL virtualization team in terms of best practices factoring in concerns like security, performance, and stability.
