英语翻译
If a virus getson to a physical machine,it will usually affect the entire machine.Virtualmachines are separate entities,therefore any viruses or problems will beisolated within that virtual machine.The physical machine and all othervirtual machines will not be affected whatsoever.Virtualization also makes iteasier to revert back to a previous state.For example an entire virtualmachine could be backed up manually at regular intervals or using the virtualmachines built in checkpoint feature,it could be reverted to a previous fullyworking state.

答案

如果病毒进入到实体机,就会影响整台机器.虚拟机器都是独立的,因而任何病毒或问题都是独立的.实体机和其他虚拟机无论如何都不会受影响.虚拟化也使机器容易恢复到原来的状态.例如,可以对整台虚拟机定期做手动备份,或者用在检查点功能配件建的虚拟机进行备份,机器可以恢复到先前的全部工作状态.
