When
a Star
Student Project guest OS is terminated abnormally, for
another example, important data stored in the Star Student
Project guest file system cache will be lost Star
Student Project. Thus, there is a tradeoff among
performance, data reliability, simplicity, and Star Student
Project generality. Though the Star Student
Project host file system is supposed to manage the I/O
operations on behalf of the guest file systems, the requirement of synchronous Star
Student Project I/O makes the management less effective
and less efficient. On the other hand, Star Student
Project is common that the guest is usually less stable
than the hypervisor layer.
