在本实施例中提供了一种数据的传输方法，图2是根据本发明实施例的数据的传输方法的流程图(一)，如图2所示，该流程包括如下步骤：
步骤S202，在确定第一虚拟机与第二虚拟机建立连接之后，创建第一快速连接结构，其中，第一虚拟机和第二虚拟机均与同一主机连接；
步骤S204，将第一快速连接结构发送给第二虚拟机，以指示第二虚拟机建立第二快速连接结构；
步骤S206，利用第一快速连接结构和第二快速连接结构进行数据传输。
通过上述步骤，由于第一虚拟机在确定与第二虚拟机建立连接之后，创建第一快速连接结构，并将第一快速连接结构发送给第二虚拟机，以指示第二虚拟机建立第二快速连接结构；利用第一快速连接结构和第二快速连接结构进行数据传输。使得第一虚拟机和第二虚拟机之间的数据传输路 径简化。因此，可以解决相关技术中存在的虚拟机之间的通信路径较长，数据传输低效的问题，达到提高数据传输效率的效果。
可选地，上述步骤的执行主体可以为虚拟机等，但不限于此。
需要说明的是，本实施例中的第一虚拟机对应于上述中的虚拟机A，第二虚拟机对应于上述中的虚拟机B。本实施例并不限于两个虚拟机之间的数据传输，超过两个虚拟机之间的数据传输原理同上。

第一步：第一虚拟机与第二虚拟机之间的连接，具体为：
第一虚拟机向第二虚拟机发送设置为请求建立第一虚拟机和第二虚拟机之间的连接的连接请求；及时第一虚拟机发起的连接请求，也可以是第二虚拟机先发起连接。
接收第二虚拟机返回的设置为响应连接请求的第一确认消息，其中，第一确认消息中还包括同步字符(synchronous Character，简称为SYN)，设置为虚拟机之间的数据同步；第一确认消息可以是ACK(Acknowledgement)。
本实施例中的第一快速连接结构和第二快速连接机构可以是快速连接的关键结构ksock，将ksock及应答第一虚拟机的ACK发送到第二虚拟机。根据第一确认消息确定第一虚拟机与第二虚拟机建立了连接。
需要说明的是，通过以下方式将第一快速连接结构发送给第二虚拟机：将携带第一快速连接结构的第二确认消息发送到第二虚拟机。
第二虚拟机收到ACK包后，检查ksock结构是否有效，在有效的情况下创建对应第二虚拟机的ksock结构(即第二快速连接结构)，并将第二虚拟机的ksock和第一虚拟机的ksock相互建立关联(即通过虚机A的ksock可以访问到虚机B的ksock，反之亦然)。
第一虚拟机在执行connect命令的时候检查第一虚拟机的ksock结构， 如果其关联的对端(此处即第二虚拟机)的ksock结构有效，则创建共享内存设置为数据传输。到此快速连接建立完成。共享内存是在主机中的。
第二步：数据传输，具体包括：

第一虚拟机在执行connect命令的时候检查第一虚拟机的ksock结构，如果其关联的对端(此处即第二虚拟机)的ksock结构有效，则创建共享内存设置为数据传输。到此快速连接建立完成。共享内存是在主机中的。
第二步：数据传输，具体包括：
在建立的第一快速连接结构中的数据和第二快速连接结构中的数据之间的映射关系有效的情况下；第一虚拟机利用虚拟网卡前端驱动将数据拷贝到共享内存中；
在进行通信之间，第一虚拟机和第二虚拟机之间通过握手达成通信协议，图3c是本实施例中的虚拟机之间的握手过程示意图，如图3c所示，虚拟机A和虚拟机B通过三次握手的方式达成通信协议。
