In my opinion enterprise virtualization provides:
- high availability (a cluster ?)
- acceptable performance
- templates for Linux OS
- possibility of using corporate standard of separated networks dedicated for
- serving service
- administration (let's say a console)
- backup solution
- hot (live) migration of virtual domains
- consolidated backup
- VLAN tagging support
I dediced to use RedHat Linux 5, which is a standard linux distribution in my company.
All the features are possible to implement using RHEL5 but it is relatively complicated to have all of them working together.
In next few weeks I hope to show how to build such solution without spending money on dedicated software.
