我开始使用 Rancher 和 Vagrant 来创建我的本地开发环境。我已经完成的步骤：
- 我已经安装了 VirtualBox。
我下载并安装了适用于 linux 的 Vagrant 包
sudo rpm -i vagrant_1.7.2_x86_64.rpm
流浪版本：
vagran --version
Vagrant 1.7.2
我从 GitHub 克隆了 Rancher 存储库：
git clone git@github.com:rancherio/rancher.git
其中有 Vagrant 文件。执行后：
sudo vagrant up
这是我得到错误的步骤，我得到了这个：

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
systemctl start system-cloudinit@-var-tmp-hostname.yml.service
Stdout from the command:
Stderr from the command:
Job for system-cloudinit@-var-tmp-hostname.yml.service failed because a configured resource limit was exceeded. See "systemctl status system-cloudinit@-var-tmp-hostname.yml.service" and "journalctl -xe" for details.
然后当我访问 localhost:8080 时，没有安装 Rancher UI。
