[bala suru]

Hi,

I have used a some simple way to copy the image running Vm image(insted of
onevm saveas) ,
1. I did some modification over the running image(creating some files)
2. issued onevm suspend
3. copied var/images/  file of the running image
4. Registered the above copied image as a new image
5 . launched the new VM using above image

But I could not see any modified files on this VM ,,?

Are the steps which I followed are correct ..?

[one-users] XML-RPC API 2.2 - Session string when ssh authentication

[Javier Diaz]

Hi,
I am using OpenNebula 2.2 and I have a program that interact with it 
using the XML-RPC API for python. The authentication in OpenNebula has 
been configured to use the ssh keys.


I can interact with OpenNebula using the oneadmin user with a session 
string like :. However, when I try to do the 
same for a normal user : it does not 
work. I have tried different session string but I didn't find the right 
one. So, what is the structure of the session string that I need to use?


Thanks in advance.

Regards,
Javi

once again i reran the program, still getting same error.
JAVA API code

OneResponse or = Host.info(Client, 18);
if(or.isError()){
   System.out.println(" Check for error "+or.getErrorMessage());
  }
else{
 System.out.println(or.getMessage());
 }


the response for this code error Failed to parse servers response: Unknown
type: string

I am thinking OneResponse return TRUE, because "Check for error" is missing
in the output

Hi,

I can't reproduce this problem. Can you provide more information?

What OpenNebula version are you using?
What's the output of "onehost show  -x"?
Any trace?

Hi,

I am running Opennebula 2.1.8. When specifying the context for a VM, if
I specify a URL in the "files" attribute, the contextualization fails.
Consider, for example, the following context:

CONTEXT=[ files="http://domain.com/test.xml"; ]

When I try to create the VM with such context, I get the following error
message:

tm_context.sh: Executed "mkdir -p /srv/cloud/one/var//106/images/isofiles".
tm_context.sh: Executed "cp -R /srv/cloud/one/var/106/context.sh
/srv/cloud/one/var//106/images/isofiles".
tm_context.sh: ERROR: Command "/usr/bin/wget -O
/srv/cloud/one/var//106/images/isofiles http://domain.com/test.xml"; failed.
as far as I understand the file (http://domain.com/test.xml) needs to be 
put into isofiles dir ( /srv/cloud/one/var//106/images/isofiles) whereas 
-O option for wget means that file has to be saved as one specified in 
argument of -O option.

I would try to replace -O option of wget command in line
exec_and_log "$WGET -O $ISO_DIR $f"

of  $ONE_LOCATION/lib/tm_commands//tm_context.sh file by -P 
option i.e.


exec_and_log "$WGET -P $ISO_DIR $f"

HTH,
Nikolay.

Error excuting image transfer script:
/srv/cloud/one/var//106/images/isofiles: Is a directory
I presume that specifying a URL in the file attribute is allowed, since
Opennebula uses "wget" to fetch the file (otherwise, if a local file is
specified, Opennebula uses "cp" to copy the file to the isofiles directory),
but the command that Opennebula runs is not correct. Is this a bug? Or am I
wrong thinking that a url can be specified?

[one-users] New community wiki

[Borja Sotomayor]

Hi everyone,

The OpenNebula community wiki has been moved to its own site:

http://wiki.opennebula.org/

If you had an account on the old wiki (under www.opennebula.org), your 
account should still work on the new wiki.


Cheers!

I tried may of the suggestion provided but still I same error exist .
http://lists.opennebula.org/pipermail/users-opennebula.org/2011-March/004394.html

I can suspend/Resume the VM this and all works fine ,

Hence I wanted to try some different method ..

I need to save modified VMs as new one ->
 here can I do normal copy and save the VM which is running and modified ..?

Can I deploy the new VM using the save Image ..?

[one-users] Building the first Cloud

[Valentin Bud]

Hello Community,

 I am about to embark in the journey of building the first Private Cloud. At
first it will be tested by the staff and
afterwards it will be deployed in production. I have read until now quite
some documentation about Cloud Computing
and I've successfully installed OpenNebula 3.0b2 from source.

 I have looked for information regarding Cloud Architecture and Design and
found out that literature on this subject
is quite scarce. Anyway I have found some presentations from CERN and the
OpenNebula blog post about the CERN Cloud, and
pieces start to fall into place. Great piece of technology this Cloud
Computing paradigm.

 I want to deploy a Private Cloud to automate the deployment of an
application we use for our customers. The application (a database)
uses the hard disk quite a lot to index large amounts of data. So I thought
I would deploy OpenNebula using the LVM storage driver. This way I can
balance the load
among the servers. Maybe in the future when the Cloud will be used at its
full potential and the needs will grow I will switch to NFS
on some decent hardware that can support the intensive read/write
operations. Another argument why I choose LVM is the possibility to
grow the volume and so the filesystem inside the VM in case of need. I need
to test if its possible to do this without shutting down the
database service.

 I don't want to waste your time Gentlemen but being my first try on
building a Cloud I thought I come here and post what I want to do
and receive some feedback from you. I do have some questions though. First
and foremost I come from the BSD world and I can't
say I'm a Linux advanced user and have a favorite distro. So which operating
systems in terms of features (security, networking, ease of administration,
etc) should I choose
to use for this Cloud. I usually choose the one I know best but as I have
mentioned I don't have a Linux operating system I know best.
I am thinking of using CentOS because KVM, which lies at the core of the
Cloud I want to build is actively developed and maintained by RedHat. I
assume
it works best on the operating system these guys develop.

 What other things should I research, what gotchas, what hints do you have
for a Cloud newbie? I want to build Clouds, I really like the concept and
the vision Cloud Computing brings in our times. For this I have to study and
gain experience, I know that. Any kind of thoughts you have
I appreciate them.

Thank you,
v
