试试VirtualBox& Vagrant和我的初始lucid64虚拟机无法解析us.archive.ubuntu.com但可以解析security.ubuntu.com,google.com和www.apple.com(但不是apple.com w / out the www？！？！ ).
运行VM的主机可以解析us.archive.ubuntu.com以及其他所有域.
不知道发生了什么事？！？

香草装置.我的第一次尝试.按照部署Rails一书中的说明进行操作.
编辑：添加/etc/resolv.conf：
vagrant@lucid64:~$cat /etc/resolv.conf nameserver 10.0.2.3 domain mydomain.com search mydomain.com
还有一些挖掘信息：
vagrant@lucid64:~$dig us.archive.ubuntu.com ;; Truncated,retrying in TCP mode. ; <<>> DiG 9.7.0-P1 <<>> us.archive.ubuntu.com ;; global options: +cmd ;; connection timed out; no servers could be reached
但是当使用跟踪标志时似乎解析了域名？！？ (或者我读错了吗？)

我通过将下面的行添加到我的Vagrantfile来解决了这个问题：
