Re: [one-users] sunstone configuration issues

As Peter pointed out:

"sunstone-server -H X.X.X.X -p  start" should work. It could be that
you were placing this parametres after "start", so they are not being
recognized.

I believe sunstone server is not well prepared to work with a reverse
http proxy due to the use of absolute paths, so this could be the reason.

There is an issue tracking this and some patches available, including
for 2.2:

http://dev.opennebula.org/issues/548

Can you try and see if the problem is solved then?

Hope it helps,

[one-users] problem with ebtables-xen OpenNebula

[高建平]

Dear 
  
  I have some problem when I using ebtables to isolate vlans. My OpenNebula 
version is 1.4,and  i'm using Xen(3.0.3) and centos(5.4;nodes os). and I have 
done sone configuration according to Private Cloud Computing with OpenNebula 
1.4 document:
  1. install ebtables and configure sudoers on every nodes. 
  oneadmin ALL=(ALL) NOPASSWD: /usr/local/sbin/ebtables*
  2. modify my one configure, /opt/nebula/ONE/etc/oned.conf:
  VM_HOOK = [
name="ebtables-start",
on  ="running",
command ="/opt/nebula/ONE/share/hooks/ebtables-xen",
arguments   ="one-$VMID",
remote  ="yes" ]
 VM_HOOK = [
name="ebtables-flush",
on  ="done",
command ="/opt/nebula/ONE/share/hooks/ebtables-flush",
arguments   ="",
remote  ="yes" ]
but when VM is created the ebtables rules is empty,and the oned.log 
has this msg:

Re: [one-users] Problems using OpenNebula EC2 interface

[Daniel Molina]

Hi Lars,

I think the best solution would be to change the econe client
implementation to use the sha1 password, therefore the EC2_SECRET_KEY
can be used in the same way for the three clients. The priority is CLI
> ENV > ONE_AUTH

I have opened a ticket regarding this issue to include it in the next version:
http://dev.opennebula.org/issues/618

Regards.

Re: [one-users] having a problem when shut down a VM

[Carlos Martín Sánchez]

Hi,

>From the libvirt doc. [1]:
ACPI is useful for power management, for example, with KVM guests it is
required for graceful shutdown to work. If you set ACPI = YES, then your VM
should have the ACPI daemon running and be configured to shutdown with the
ACPI signal . For instance, I think Ubuntu Desktop shows the log out menu
instead.

Carlos

Re: [one-users] OCCI version

[florian.feldhaus]

Hello Zeeshan,

in OpenNebula currently only version 1.0 is supported, but we started
development for OCCI 1.1. An official announcement of the project as
OpenNebula Ecosystem project is planned for next week. We still need to
tidy up a bit and add some usage notes.

The Sourcecode can be found at:
http://dev.opennebula.org/projects/ogf-occi/repository

Until further notice, the sourcecode is still considered experimental!

Cheers,
Florian

Just a small query, OCCI does provide COMPUTE element right ?  do you see
any use of wrapping OVF under OCCI ?

Yes, upcoming ONE release will ship with a Template Pool, to be able
to instantiate VMs from predefined templates.

Delete a VM is like unplugging the power cord (the FS can break), adn
plus the image is not transfered back (even if the SAVE flag is
present). Shutdown represents a more clean approach, the VM is cleanly
shut down, and the image saved if marked so.

For this use case, you will need an (easily to develop) new component,
a Service Manager, that will use values from ONE monitoring to decide
to launch or shutdown VMs.

Re: [one-users] problem with ebtables-xen OpenNebula

[Jaime Melis]

Hi,

change lines 54 and 55 of ebtables-xen script to reflect the full path of
the xm executable (typically /usr/sbin/xm).

I suggest you migrate to OpenNebula 2.2

cheers,
Jaime

[Steffen Neumann]

Hi, 

one add-on question:

On Fri, 2011-05-06 at 12:15 +0200, Tino Vazquez wrote:
...

Is that atomic ? Or under file locking control ?

If I have some place, say /srv/could/goldenimage/ubuntu.img
where my disk image file is stored, does shutdown then overwrite
the existing ubuntu.img, and what happens if during the XX seconds
of writing back a new VM is created from ubuntu.img ? 
Unless "save" is atomic, the new VM will fail on a half-written 
mix of old and new. Or did I miss anything ?
What happens if three VMs created off ubuntu.img shutdown 
simultanously ? Will each write its changes back 
into that single ubuntu.img ?

Yours,
Steffen

Dear 
  
  I have some problem when I using ebtables to isolate vlans. My OpenNebula 
version is 1.4,and  i'm using Xen(3.0.3) and centos(5.4;nodes os). and I have 
done sone configuration according to Private Cloud Computing with OpenNebula 
1.4 document:
  1. install ebtables and configure sudoers on every nodes. 
  oneadmin ALL=(ALL) NOPASSWD: /usr/local/sbin/ebtables*
  2. modify my one configure, /opt/nebula/ONE/etc/oned.conf:
  VM_HOOK = [
name="ebtables-start",
on  ="running",
command ="/opt/nebula/ONE/share/hooks/ebtables-xen",
arguments   ="one-$VMID",
remote  ="yes" ]
 VM_HOOK = [
name="ebtables-flush",
on  ="done",
command ="/opt/nebula/ONE/share/hooks/ebtables-flush",
arguments   ="",
remote  ="yes" ]
but when VM is created the ebtables rules is empty,and the oned.log 
has this msg:

Re: [one-users] Beginner questions: Opennebula 2.2.1

[Tino Vazquez]

Hi,

It is not atomic, and in fact is asynchronous. There are various save
and save_as choices (take a look in the documentation). If you are
using NFS with a persistant image, you can bump into this sort of
situations, so special care must be taken with this kind of VMs.

Regards,

-Tino

Hi Zeeshan,

work is already in progress regarding OVF and OCCI. For more information
ask on the OCCI WG Mailinglist.

Indeed the problem was in wrong returning value of deploy script. Fixed now.
Thanks a lot, Tino!

Was not it OCA that to use in OpenNebula ? Wrapper for wrapper OCA allows
a closer translation ...

Re: [one-users] Unable to Stop Running VM

[Koushik Annapureddy]

Hello All,

I found that issue for "stop" command is that  chown command in NFS is not
working . Node is not able to perform chown operation on checkpoint file i.e
(for example) /srv/cloud/one/var//12/images/checkpoint.  Here is the
detailed information about my NFS setup configuration details and issue I am
facing.

It would be great if anyone can help me in solving this issue

I have create a NFS server (IP: 192.168.2.3) with following export
configuration at /etc/exports:

Code:

/srv/cloud 192.168.2.4(rw,async,no_subtree_check,no_root_squash)

>From machine 192.168.2.4 I have following configuration in /etc/fstab:

Code:

192.168.2.3:/srv/cloud  /srv/cloud  nfs rw,hard,intr0   0

Now from machine 192.168.2.4 with root user, I create a file
"/srv/cloud/xyz" and then change the ownership of the file to user
"oneadmin". I have following commands and the error in the output:

Code:

#touch /srv/cloud/xyz
#chown oneadmin:oneadmin /srv/cloud/xyz
chown: changing ownership of `xyz': Invalid argument

I have user "oneadmin" at both server and the client machine with same user
and group id:

At client:
Code:

#id oneadmin
uid=9000(oneadmin) gid=9000(oneadmin) groups=9000(oneadmin),110(libvirtd)

At server:
Code:

#id oneadmin
uid=9000(oneadmin) gid=9000(oneadmin) groups=9000(oneadmin)

What could be the problem in changing the ownership of the file from the
root user at nfs client machine when "no_root_squash" has been specified?

Thanks
Koushik

Re: [one-users] onevmware register error

[Tino Vazquez]

Hi Antoni,

Not sure if VMware server disks are a little bit different. If the
following works:

onevmware register --disk-vmdk
/srv/cloud/one/var/vmUbuntu2/vmUbuntu-copy.vmdk --disk-flat /etc/hosts
vmUbuntu.one

and the VM boots properly from that image, then we'll make the flat
disk optional to support VMware server.

Thanks a lot for your feedback!!!

Regards,

-Tino

Re: [one-users] Unable to Stop Running VM

[Neumann, Steffen]

Hi,

we also had that behaviour with NFS4 on ubuntu 11.04, 
and rpc.idmapd was not running because we had /var
on a different partition than / and idmapd wanted to store
stuff in the not-yet-mounted /var. Solution is a single filesystem
for / and /var. Is that the case in your setup ?

Yours,
Steffen
