我遇到了一个问题，即流浪汉启动了VM，它的第二个接口eth1无法从DHCP服务器获取公共IP
流浪文件
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.ssh.forward_agent = true
config.vm.define "test-vm" do |s|
s.vm.box = "ceph/ubuntu-xenial"
s.vm.hostname = "test-vm"
s.vm.network :public_network,
:dev => "br0",
:mode => "bridge",
:type => "bridge",
:use_dhcp_assigned_default_route => true
end
end
当我无所事事时
sudo vagrant up

现在它停留在“配置和启用网络接口”上的时间确实非常长，而接口eth1长时间没有获得IP
最终，接口在大约10分钟后获得IP。为什么会这样？
之前：

eth1没有公共IP
10分钟后-确实很长，eth1获得了IP，这时候我的脚本也失败了
