我最近在 Ubuntu 12.04 主机上升级到了 Vagrant 1.7.4。我有一个开发虚拟机，过去一年来我每天都在运行它。升级后，vagrant 不再为 Vagrant 文件中定义的私有网络创建网络接口。
我的 Vagrantfile 如下所示：
# -*- mode: ruby -*-
# vi: set ft=ruby :
# Vagrantfile API/syntax version. Don't touch unless you know what you're doing!
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = "devbox-4"
config.vm.network :forwarded_port, guest: 11211, host: 11211
config.vm.network :forwarded_port, guest: 5672, host: 5672
config.vm.network :forwarded_port, guest: 5432, host: 5432
config.vm.network :private_network, ip: "192.168.255.10"
end
虚拟机内部运行 ifconfig 输出以下内容
eth0 Link encap:Ethernet HWaddr 08:00:27:83:e7:ad
inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0

正如您所见，定义的私有网络并不存在。
据我所知，指定网络接口的方式在 Vagrant 1.7.4 中没有改变，所以我遗漏了什么？
我对所涉及的各种程序的版本如下：
Host OS: Ubuntu 12.04
Vagrant: 1.7.4
Virtualbox: 4.2.20
Guest OS: Ubuntu 12.04
此外，当我启动虚拟机时，我在输出中看到以下几行：
default: Warning: Connection timeout. Retrying...
default: Warning: Remote connection disconnect. Retrying...
default: Warning: Remote connection disconnect. Retrying...
在启动过程继续之前，重试行大约会显示十几次。它以以下内容结尾：
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
/sbin/ip addr flush dev eth1 2> /dev/null
Stdout from the command:
Stderr from the command:
但是然后我可以使用 vagrant ssh 顺利地 ssh 到 VM。
