Re: [one-users] Express Installation Script.
Hi, Sorry for the delay, was away from work due to weekend. I could not reproduce the same error again and I do not have old logs as of now. Shall surely update next time i get the same issue. As for creating 10vms with single command using the loops , how will it work. All the vms will have same vnc port and same name. I think there should be the option with the command line itself as people would like to create multiple vms in cloud.

Re: [one-users] Express Installation Script.
I am sorry. I haven't said that 755 are the wrong permissions. Just that being new using opennebula i have encountered some permission denied errors and by making the folder world-writable i have avoided them. I have just mentioned as a quick fix to give everybody access to /var/lib/one. I assume my problem originated from the oneadmin user being created without necessary access rights. Because oneadmin also needs write permissions and i think(excuse me if i am wrong) 755 means read-only for anyone other than root. So my oneadmin user created from the install script does not have write access needed for every opennebula operation as the one.db and virtual machines files are there(images and deployment files). But i insist, this might just be due to an incorrect installation process performed by me and not due to incorrect access rights. Regards, Daniel Hello, thank you both for reporting these issues.

Second, i found that it did not create /var/lib/one with coresponding access rights. So, in order to make the opennebula node work you need to take some steps each time the node is restarted(i am using Ubuntu server): 1. Copy the content of /usr/lib/one/remotes from the machine where nebula client is installed to /tmp/one ( create /tmp/one) on the nebula node 2. sudo mkdir /var/lib/one (if folder does not exist) 3. sudo chmod 0777 -R /var/lib/one (just to be certain give anyone rights to access one) Also, i have found that on the nebula client machine i need to perform some similar tasks after system restart because folders keept disappearing: 1. export ONE_AUTH=/$HOME/.one-auth 2. export ONE_XMLRPC=http://localhost:2633/RPC2 3. sudo mkdir /var/run/one 4. sudo mkdir /var/lock/one 5. sudo chmod 0777 /var/run/one 6. sudo chmod 0777 /var/lock/one 7. one start Hope this helps, because even with the express install configuring nebula takes time. For example, the express install does not have any means of adding the rsa key to the authorized_keys of the nebula client so even if the deploy will work, the stop of a virtual machine fails. In this case the authorization keys have to be passed manually. Hi All, I think that the express installation script has some issues, I have been struggling for successful installation of OpenNebula 2.0 for past few days. The variable *ONE_LOCATION=/srv/cloud/one *is used in the script but I do not see any such folder created by the script later. When I try to deploy vms , it get created in /var/lib/one/ and the error logs shows that theres some permission issues. Please let me know if anyone has also face the same issue and got it resolved.
