- Easy maintenance of hypervisors and supporting infrastructure thanks to migration
- Legacy workloads to run on decent and supported HW
- Less maintenance work due to less HW
- Better testing due to predictable runtime environment
Makes multi-server and multi-site redundancy economically viable for many organisations.
- Freeze and store guest state
- Roll back changes with ease
- Enabled through Copy-On-Write disk storage and/or overlay file systems
