[one-users] Using Opennebula with a uncommon Xen-configuration

[Andreas]

Hi, 

since i hear a  speech from Tino Vazquez on the OSDC in Germany (which was 
really good), im very interested in opennebula. 
After reading documentation und testing some parts there seems to be a problem 
with our uncommon Xen-configuration.

We have no central storage for the images. The images are copied over ssh to 
the hosts (Dom0).
Our DomUs based on LVM-partitions, which are directly mounted in the DomU. 
They appear as a partition and not as a disk in the DomU.  
The disk configuration for a DomU is like following:

 'phy:/dev/system/helios-1_root,hda1,w'

To save a DomU we mount the LVM-Partition in the Dom0 and make a tar-archive 
of the files and directories in the partition. A copy of the kernel and the 
initrd  is provided in the Dom0 to start the DomU with the Xen-bootloader.

Does support Opennebula such a type of configuration and if not, how difficult 
it is to adjust it? Where i must start, if i want integrate these 
configuration?


Thanks,
Andreas

[one-users] sunstone auth problem

[Robert Parrott]

Hi,

Trying to test out OpenNebula with sunstone, and am unable to
authorize through sunstone. A little debugging shows that calling the
UserPool method for the user returns an empty password hash.

I see in the logs that oned reports that a method is executed:

   Tue Apr 12 23:41:25 2011 [ReM][D]: UserPoolInfo method invoked

but the call returns "nil" in the sunstone code.

I can otherwise authenticate from the command ,ine using the typical
~/.one/one_auth file.

Any thoughts about what to look for to resolve this?


Thanks,
rob

Re: [one-users] apache for a ssl proxy with econe

[Steven Timm]

Hi Sebastien--we have this working with pre-release
opennebula 2.2 at Fermilab and have contributed our
patches back to the trunk.  We've confirmed
that we can still use hybridfox to talk to the resulting combo.

More details contact us offline.

Re: [one-users] Java OCA: poor choice of Exception class

[Carsten.Friedrich]

Some time ago I wrote a Java OCA client library based on JAXB bindings and 
posted it to this group. Have a look in the achieve and see if that suits you 
better than the stock version. It's not complete as I had to 
reverse-engineer/guess the XSD from XML output and mostly focus on part I 
actually use. There is an updated version I can probably make available if 
there is interest.

Re: [one-users] econe vm templates

[Daniel Molina]

Hi,

There is no problem on the econe server side, you can define as many
types as you want and name them as you want, the server will handle
it. The problem is in the client side, for example the econe client
uses the amazon-ec2 gem where you can find the following code snippet:

raise ArgumentError, ":instance_type must specify a valid instance
type" unless optio
ns[:instance_type].nil? || ["t1.micro", "m1.small", "m1.large",
"m1.xlarge", "m2.xlarge", "c1.medium", "c1.xlarge", "m2.2xlarge",
"m2.4xlarge", "cc1.4xlarge"].include?(options[:instance_
type])

therefore you will have to use one of those names or modify the gem
source. I think that other client utilities have the same restriction.

Regards.

[one-users] how to predeploy image

[Łukasz Grabowski]

Hi,

I am using OpenNebula 1.4 and Haizea 1.0. I want to predeploy an image so
that the VM could start at the scheduled by haizea time.
How can I predeploy a VM's image? I would appreciate clarification.

I had several ideas how to make it work but I didn't succeed.
1. I tried to copy a prepared image to the default directory
(/var/lib/one//images/) in which it should be stored when a new VM is
created.
2. Then I tried to do the same and to create transfer.0.prolog file (after
reading one of the generated by opennebula) but it didn't work.
3. I tried even set the source in DISK section in VM template to the copied
file in the destination.
However, everytime I can see in VM log, that the image is copied.

I am enclosing VM log and VM template

Re: [one-users] Opennebula Deltacloud Adaptor

[Daniel Molina]

Hi,

The Deltacloud Adaptor was developed on OpenNebula 1,4 and
deltacloud-core (0.0.1), but it should not be difficult to update it
to the last versions.

Regards.

[one-users] econe vm templates

[sebastien goasguen]

Hi,

When configuring econe.conf we specifiy the possible instance types:

# VM types allowed and its template file (inside templates directory)
VM_TYPE=[NAME=m1.small, TEMPLATE=m1.small.erb]
VM_TYPE=[NAME=m1.medium, TEMPLATE=m1.medium.erb]

Is it possible to use any naming convention for the templates or are
we limited to the same as EC2 ?

for example can I write something like this in econe.conf:

VM_TYPE=[NAME=medium.onecore, TEMPLATE=medium.onecore.erb]

Which will let users do:

econe-run-instances -t medium.onecore

thanks ?

I restarted the host machine before deployment of the VM, so VM services 
should be initiated.


BTW: I found out that the host CPU has no support for the virtualization 
instruction set required by KVM. Can it be the cause of the above 
failure ? Or should KVM revert automatically to another state to 
continue deployment ?


I'm glad to provide more output from logs if necessary.

Hi,

I have two VMs running with onevm list. But after I added the lines you 
indicated at the end of the file I get:


OpenNebula vms info return code
nil

Not sure what's wrong here...
Thanks a lot for your help Tino.

Re: [one-users] onehost register problem

[Héctor Sanjuán]

You need passwordless ssh access to the desired host.

To do that you need to use ssh-keygen, copy the generated public key to
the remote host and add it to .ssh/authorised_keys.

Hope it works,

Hector

Hi Zaina,

Let's see why the "vms.info" is failing, please add the following to the file:

--
rc = vms.info

my_file.puts "OpenNebula vms info return code"
my_file.puts rc

Hi,

It could be a browser problem (any chance of updating? or testing with
Chrome?). Even if it's not probably the extension firebug can give you
some information if the problem is on the client-side javascript, and
would allow you to inspect more closely the data sent to the sunstone
server when a new VM is created and the returned information.

You can also try updating OpenNebula to the latest release (2.2) as
there were a few bugs fixed.

In any case, can you attach the sunstone.log? Just to make sure we
didn't miss anything in there.

Thanks,

Hector

Which browser?

  
  

Firefox 3.0.6


Does the "new" VM button pop up a VM creation form at all or does the
problem happen after you submit this form?

  
  

After summit the form, nothing happens


On the second case, Are you using any of the wizards of the form or the
"advanced" mode using an ONE template?
  
  

We probe both of them. They not work


(Note that "deployment" and "creation" are different things. The "new"
buttons helps you create a VM. This VM is later "deployed" in a host).
And all VMs should appear in the list, whatever their status is.

  
  

After push the "create" button of the VM creation form, nothing happens

We are attempt to deploy a virtual machine by using the "new" button

No error appears in the sunstone.log file. The new machine don't appear

Any idea??

time --- back time  
•the client call backup_vm(), oned will be shut the vm if vm is running
•after confirm the vm stopped ，oned will vm images directory copy to the dir 
:/one_images/backup/vid-bid:

Re: [one-users] Sunstone donot deploy machine

[Héctor Sanjuán]

Hi,

It could be a browser problem (any chance of updating? or testing with
Chrome?). Even if it's not probably the extension firebug can give you
some information if the problem is on the client-side javascript, and
would allow you to inspect more closely the data sent to the sunstone
server when a new VM is created and the returned information.

You can also try updating OpenNebula to the latest release (2.2) as
there were a few bugs fixed.

In any case, can you attach the sunstone.log? Just to make sure we
didn't miss anything in there.

Thanks,

Hector

No, that's how you configure how a server should LISTEN,
you can restrict that to interfaces, and 127.0.0.1 
would be lo instead of eth0. You can also set HOST="0.0.0.0"
and it'll listen on all interfaces, IIRC.

Does the "new" VM button pop up a VM creation form at all or does the
problem happen after you submit this form?

  

After summit the form, nothing happens

On the second case, Are you using any of the wizards of the form or the
"advanced" mode using an ONE template?
  

We probe both of them. They not work

(Note that "deployment" and "creation" are different things. The "new"
buttons helps you create a VM. This VM is later "deployed" in a host).
And all VMs should appear in the list, whatever their status is.

  

After push the "create" button of the VM creation form, nothing happens

Hector

Hi:

We are attempt to deploy a virtual machine by using the "new" button

No error appears in the sunstone.log file. The new machine don't appear
in machine view, and not listed in the fail machine list...

Any idea??

Re: [one-users] Java OCA: poor choiche of Exception class

[Gian Uberto Lauri]

According to the last update in  issue #572

> "r" == redmine   writes:

r> Issue #572 has been updated by Ruben S. Montero.

r> Target version changed from Release 2.2 to Release 2.4

r> This is initially scheduled for 2.4

does the OpenNebula team plan to  include my contribution in the code,
and  if  yes, which  kind  of  exception  (the  Error or  the  Runtime
Exception) ?

I ask  this because I  am working on  a OVF aware  OCCI implementation
that relies on the OCA API (for Venus-C)  and I wonder if I can use my
modified code now or this spells trouble.

Zeeshan, your opinion is welcome, too!

I have some followup questions:

1) The documentation suggests that LDAP integration was created
   for the 2.0 release: documentation:archives:rel2.0:ldap
   I assume it still (is supposed to) work with 2.2 ?

2) The user should add its credentials to $ONE_AUTH file 
   (usually $HOME/.one/one_auth) in this fashion:

user_dn:plain:user_password

   Does that mean the users have to put their passwds 
   in plain text into their homedir ?? This would be 
   a gaping security hole.
