（虚拟机）VM 内的 ls /vagrant 挂起

Posted 2023-02-16

【中文标题】（虚拟机）VM 内的 ls /vagrant 挂起

【英文标题】：ls /vagrant inside a (virtual box) VM hangs

【发布时间】：2014-02-14 16:00:44

【问题描述】：

我用下面的 Vagrant 文件配置了一个 VM（vagrant up）， 然后我“vagrant ssh”进入它， 然后 *ls /vagrant *

它永远挂起，我在下面附加了一个 strace。

虚拟盒子的链接不稳定，所以复制到这里：

https://bitbucket.org/genap/public_files/downloads/saucy-server-cloudimg-amd64-vagrant-disk1.box

这个版本也会出现挂起...

流浪者版本 1.4.3 主机操作系统版本：

  Distributor ID:   Ubuntu
  Description:  Ubuntu 13.04
  Release:  13.04
  Codename: raring

【参考方案1】：

vboxsf 挂载的问题几乎总是由来宾上的错误或不匹配的 VirtualBox 来宾添加引起的。至少主要和次要版本号必须与主机上的 VirtualBox 版本匹配。

选项有：

使用vagrant-vbguest 插件在需要时自动升级来宾添加。方便，但如果需要重新安装添加的新 VM 实例，则会减慢创建速度。 找到一个包含最新客人添加的盒子。想想你是否可以信任盒子图片的提供者。 使用匹配的客人添加版本构建您自己的盒子。例如，请参阅 packer.io 和 bento templates。 手动升级虚拟机上的访客添加，并将vagrant package和add作为新的基础框。
