[one-users] Problem monitoring ESX host with the CentOS 6.2 appliance listed in marketplace

Thu Aug 23 06:42:03 PDT 2012

I have opened a bug but it was closed.... I have no idea why this is not working.  Somehow the host info collection works when the script is run by oneadmin but not when invoked via the "onehost create" command.  Any help is welcome:

Cannot add ESX host vai "onehost create" but /var/lib/one/remotes/im/run_probes vmware runs correctly under oneadmin account

Description

When adding an ESX host to OpenNebula 3.4.1 using the CentOS appliance the host produces log similar to:

ESX host is ESX 4.1 update 1, SSH access for oneadmin is enabled, with passwords correctly added and SSH keys imported into the host.

Since the command executes correctly under the shell, I can only think of environmental variables. Could you compare the variables accesible from the vmware.rb script when ran directly on the shell compared with the ones available when ONE runs the script?

Also, are you running any sort of HTTP proxy?

Not familiar with ruby, could you provide a code snippet to show how I can show those environment variables?

No proxy here, direct connection although the system did have http_proxy set I have removed that and rebooted and symptoms remain unchanged.

Thanks

Add the following in line 46 of vmware.rb

`env > /tmp/vmware_env_vars`

Run it once from the shell, backup the file, make ONE monitor the host, and compare both files.

Thanks for the assistance, this is the difference between the version called via "onehost create" and the one run from the shell:

Please let me know if you need further information or if this bug is known to you and could be fixed by upgrading to a newer release. I have also noticed that I am unable to login to Sunstone, log error is " [E]: Error initializing authentication system" Perhaps the two are linked somehow.

I would suggest an email to the support list describing the monitorization problem, and a second one for the sunstone problem. This way other members of the community can help. I am closing this bug as it is not clear wether this is a bug or a problem with configuration. We will reopen it if we find out in the mailing list that there is indeed a bug.
