Re: [one-users] opennebula and gentoo

[Javier Fontan]

Thanks for the ebuild!

I've added the link to it in the OpenNebula documentation. It should be up
after we regenerate the pages.

Cheers

Re: [one-users] OpenNebula and FreeIPA authentication

[Javier Fontan]

The problem seems to be generated by a connection problem from the driver
to OpenNebula itself.

Can you change the file /var/lib/one/ruby/opennebula/ldap_auth.rb and
around line 89 change the code:

client = OpenNebula::Client.new
group_pool = OpenNebula::GroupPool.new(client)
group_pool.info

by

client = OpenNebula::Client.new
group_pool = OpenNebula::GroupPool.new(client)
STDERR.puts group_pool.info.inspect

After that enable mapping_generate and send me the output of the error. You
can leave that code changed as it only adds more information to errors.

Thanks

Hi Maria,

Currently, this option is not available, but we can consider including it

[one-users] Query regarding system & image datastores

[ngurjar]

Hi,
I am planning to setup OpenNebula Cloud.
I want to decide storage for System & Images datastore and also storage 
on host.


I want to use Shared Storage using iscsi over fiber.
In this case, when I create VM how image will be transfer to System 
datastore and how it will be transfer to Host?


Please help me out.

Which quick start are you following?

Assuming it's this one [1], the ssh is created in the frontend.

The keys do not need to be manually copied to the nodes, because in the
previous step the /var/lib/one directory is configured to be shared via
NFS. This directory is oneadmin's home, so .ssh will also be exported to
the nodes.

Re: [one-users] Wrong state to perform action

Hi Karsten,

I don't know how to reproduce your problem... Does this happen with any
other VM? Did you try to restart opennebula?

Please open a bug at http://dev.opennebula.org and include the VM xml
output, the individual VM log file, and the RequestManager log lines from
oned.log.

With the ssh tm driver, the VM disks are saved back to the image datastore
only when the VM is shutdown, see [1].

Hi,

Which version of distribution are you using? Since I see you're 
installing with rpm packages i suspect CentOS/Suse?
Recent versions of CentOS6 (we are using 6.5) have an up to date 
libvirt/kvm package that supports Gluster.


Can you give some info about your configuration?

Vincent
