2、方式提供了10/100 /1000Mbps性能，无疑性能更好。现在，VMware ESX Server已经可以提供基于Intel E1000的千兆虚拟网卡，从兼容性和性能的角度来看，E1000都是更好的选择。但似乎，在ESX/ESXi 3.5的图形界面中，都无法直接选择该网卡类型，需要手动配置。一、为什么要用E1000原有很很 多，其中最主要的有两个：1、PCNet32 网卡太古老这个古老的意思是，该网卡已经不适应新操作 系统的要求了。而且也不支持mii-tool等检测工具，过去用虚拟客户机测试HA集群时，就无法监控虚拟的PCNet32 网卡。甚至在 Linux kernel的默认配置中，都需

3、要费一番功夫才能找到该网卡的编译模块选项。2、性能现 在的服务器基本都提供千兆的网卡，若虚拟客户机中仍只提供100Mbps虚拟网卡，性能肯定会降低的。另一方面，vmxnet与E1000的对比 中，也会发现E1000的效率更高，见这里。因此，建议把虚拟客户机中的网卡设置为Intel E1000类型。二、指定网卡类型2、默认配置在Linux中，为PCNet32 网卡：引用# lspci -v00:11.0 Ethernet controller: Advanced Micro Devices AMD 79c970 PCnet32 LANCE (rev 10)Subsystem: Advanced
