Advantages of Virtualization

Managed execution and isolation are perhaps the most important advantages of virtualization.
allow building secure and controllable computing environments.
This enables fine tuning of resources, which is important in a server consolidation and is also a requirement for effective quality of service
Portability especially for execution virtualization techniques
Java programs are compiled once and run every where. they only require that the java Virtual Machine be installed on the host.
To achieve a more efficient use of resources the underlying host, without interfering with each other.

Disadvantages of Virtualization

Performance degradation since virtualization interposes an abstraction layer b/w the guest and the host , the guest can experience increased latencies
Binary transition and interpretation can slow down the execution of managed applications
inefficiency and degraded user explain leads to an experience leads to an inefficient use of the host
Some of the specific features of the host cannot be exposed by the abstraction layer and then become an inaccesible
Security holes and new threats opens the door to a new and unexpected form of phishing
