xen + debian网络升级压缩后喘息

Question

我有一个Debian + Xen服务器。在系统升级到稳定版本之后，网络在启动后就不会出现。每次重启后，我都需要手动打开它。升级期间未更改网络配置。

这是/etc/网络/接口：

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
    address 11.22.33.44
    netmask 255.255.255.0
    gateway 11.22.33.1
    nameserver 8.8.8.8

启动后，ip r显示没有路由，eth0没有ip地址。手动ip和路由设置良好，网络开始工作。

来自dmesg的关于我发现的网络的消息(看起来没什么有趣的)

我升级了两台服务器，并对其中的两台服务器进行了这种行为。如何解决这个问题，并使网络在启动时自动启动？

Answer 1

您需要将etnernet电缆切换到另一个以太网端口，或者在配置中将eth0更改为eth1。原因是您有两个以太网接口，现在您正在配置没有电缆的接口。

注意

e1000e: eth1网卡链路上升1000 Mbps全双工，流量控制: Rx/Tx

您还可以尝试删除/etc/udev/rules.d es.d/70-Persistent-net.Rule和/或更改内容，以反映您希望它成为的任何内容。该文件决定在哪个网络接口上获取什么名称。重新启动更改或删除以生效。删除是可以的，它将被重新生成。

顺便说一句，dmesg消息也显示了peth0，所以可能只是udev将eth0重命名为peth0。删除或更改/etc/udev/ well. d/70-persistent-etc.规则也会解决这个问题。或者在配置中将eth0更改为peth0。
