问题描述

在Openstack手册中，我们提到了此链接包含，Openstack预装。

我下载了 trusty-server-cloudimg-amd64-disk1.img 文件，我使用KVM加载它。我实例化了一个虚拟机使用这个图像，但我不能登录（使用控制台）或ssh到它。

我不知道该操作系统的默认用户名和密码。

I am trying to build a cloud infrastructure using VM's

In the Openstack manuals, it is mentioned that the images in this link contain, Openstack pre-installed.

I downloaded the trusty-server-cloudimg-amd64-disk1.img file and I loaded it using KVM. I instantiated a Virtual Machine using this image but I am not able to login (using the console) or ssh into it.

I do not know the default username and password of that OS.

Also (a different question), I would like to build a Cloud using the 2 Virtual Machines, is it possible to use the same image?

解决方案

The default username for ubuntu image is ubuntu.
There is not a default password, and you can not ssh to the machine using username / password or connect through the VNC console. You have to use public / private key authentication method with ssh. Also sudo elevation for ubuntu account is passwordless.

After accessing for the first time your virtual machine, you can change those settings and enable username / password authentication for ssh.

Regarding your second question,
Yes, you can use the same image for multiple virtual machine.
