Hi Du,<br>
<br>
<br>
You have to create a keypair (ssh-keygen -t rsa) then upload the
public key to nova. Then, use "ssh -i private.key" to log in.<br>
<br>
hope this helps,<br>
<br>
cheers,<br>

<div>Hi all,<br>
<br>
</div>
I launch an instance based on ubuntu cloud-image and
head a problem:<br>
<br>
<span style="color:rgb(255,0,0)">"Permission denied
(publickey)."</span><br>
<br>
</div>
My work steps are:<br>
<br>
</div>
1. download a ubuntu cloud-image(qcow2 file format):<br>
<br>
$ wget <a href="http://uec-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-disk1.img" target="_blank">http://uec-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-disk1.img</a><br>
<br>
</div>
2. upload the image using glance client:<br>
<br>
$ glance image-create --name trusty-server-cloudimg-amd64
--disk-format qcow2 --container-format bare --is-public True
--file ~/images/trusty-server-cloudimg-amd64-disk1.img<br>
<br>
</div>
I can see the image details below:<br>
<br>
<a href="mailto:vcap@ubuntu:~/.ssh$" target="_blank">vcap@ubuntu:~/.ssh$</a> glance image-show
trusty-server-cloudimg-amd64<br>

+------------------+--------------------------------------+<br>
<br>
</div>
3. launch an instance basing on the image:<br>
<div><br>
nova boot newServer --image
db872d0d-4fd5-4955-93fd-41df8fe0c8fa --flavor 2<br>
<br>
</div>
<div>nova list<br>
</div>
<div><br>

+--------------------------------------+-----------+--------+------------+-------------+--------------------+<br>
| 261e4fec-dc96-429d-9239-65dfe3732eca | newServer | ACTIVE |
- | Running | private=10.254.1.3 |<br>
+--------------------------------------+-----------+--------+------------+-------------+--------------------+<br>
<br>
After configuring security group(all tcp 22 port):<br>
<br>
<a href="mailto:vcap@ubuntu:~/.ssh$" target="_blank">vcap@ubuntu:~/.ssh$</a> telnet 10.254.1.3 22<br>
Trying 10.254.1.3...<br>
Connected to 10.254.1.3.<br>
Escape character is '^]'.<br>
SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2<br>
<br>
<a href="mailto:vcap@ubuntu:~/.ssh$" target="_blank">vcap@ubuntu:~/.ssh$</a> ssh <a href="mailto:ubuntu@10.254.1.3" target="_blank">ubuntu@10.254.1.3</a><br>
<span style="color:rgb(255,0,0)">Permission denied
(publickey).</span><br>
<br>
</div>
<div>I guess the newServer is configured to be accessed via ssh
key. But, I have no idea what's the private key.<br>
<br>
</div>
<div>BTW, from the log of web console, I can see:<br>
<br>
<pre>newserver login: Cloud-init v. 0.7.5 running 'modules:final' at Wed, 19 Nov 2014 08:09:02 +0000. Up 480.40 seconds.
