想查看 XenServer6.2 下边的虚拟机 Ubuntu14.04 的网卡速率等信息,使用 ethtool ,mii-tool 等工具都不能返回与普通物理网卡相同的信息。有什么其他的办法么?
例如使用 ethtool:
sudo ethtool eth0 Settings for eth0: Link detected: yes sudo ethtool -i eth0 driver: vif version: firmware-version: bus-info: vif-0 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: no driver "vif" means it's a Xen Virtual Interface paravirtualized driver.
普通物理网卡返回
[apple@localhost ~]$ sudo ethtool em1 Settings for em1: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full 10000baseT/Full Supports auto-negotiation: No Advertised link modes: 10000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: No Speed: 10000Mb/s Duplex: Full Port: Direct Attach Copper PHYAD: 1 Transceiver: internal Auto-negotiation: off Supports Wake-on: g Wake-on: d Current message level: 0x00000000 (0) Link detected: yes 使用 mii-tool
sudo mii-tool eth0 SIOCGMIIPHY on 'eth0' failed: Operation not supported
