Hi,

We are installing an OpenNebula test environment and I am getting the following error when trying to start the Sunstone server:

```
[2015-07-29 16:25:39.8620 5556/7fd738602700 App/Implementation.cpp:287]: Could not spawn process for

```

Probably, I am missing to install some package/gem or I am just missing something in the configuration. In any case, if you see a clear solution to solve this error, please let me know 😄

Thanks in advance,  
Esteban

Yes you probably missing following command in installation process:

> /usr/share/one/install\_gems

Above commend installs all necessary ruby modules for OpenNebula. If you have not run the install\_gems script, please do.

Hi @kelepirci,

Thanks for answering me 😄

We have decided to separate the OpenNebula, Sunstone and APP-Market in three different nodes, so I was just installing the appmarket RPMs on the APP-Market node. But it is also necessary to install the appmarket RPMs on the SunStone node in case of having OpenNebula, SunStone and APP-Market installed in different machines, or otherwise, it will not be possible to start sunstone server.

Thanks,  
Esteban

hi and sorry for reupload the topic.

there are any solution to have Sunstone and Appmarket in differents nodes? because at now its only possible as @esfreire say… install appmarket in sunstone server and again install appmarket in other node.

SeeU 🙂

No, they have to be in the same node.
