use-cases
Common scenarios for SLA in oVirt
Private-cloud / multi-tenancy models
- Limitations / Capping (CPU, RAM, TBD…)
- Allow limiting a VM’s resource consumption
- Provide better control on VM behavior and prevent a VM from going wild.
- Quota
- Management level limitations
VM High Availability
- Host level
- Tagged hosts should be used when scheduling HA-VMs.
- VM level
- allow auto-reset when guest fails (blue screen, etc.)
- Application level
- monitor specific application(s) and act accordingly (reset, migrate, etc) when it stops responding
HW utilization
- Memory Over Commitment
- Allow running more VMs than available physical memory
Power saving
- Shutdown idle VMs
- Gather all VMs to several hosts (load balancing, already exists) and shut down / suspend unused hosts.
Advanced VM scheduling
- Time based: turn on/off at a given time
- Various algorithms implementations
- Statistic-based scheduling
