Re: [one-users] Opennebula - Adding esx host

[Tino Vazquez]

Hi Arun,

I was missing the vmware argument, let's try this (note the vmware at the
end):

# $ONE_LOCATION/lib/mads/one_im_sh vmware

MONITOR 0 10.209.34.135 -

[one-users] XML interface to open nebula

[bharath pb]

Hi,
I’m new to the cloud computing softwares , I have selected Open Nebula for
creation for virtual cloud for the sensor data .

My work is to create a virtual sensor cloud, so that end users can access
the sensor data etc .

I have a sensor network which gives the real-time data to the PC, at PC I
have a driver which I can receive the data and put in to XML format.

Now I’m facing lots of problem at the interface of this in to the open
nebula.

How to interface this xml to the open nebula..?
Do I really need to create a VMs because my cloud just has to provide (IaaS)
service to the end user queries   , quires may be “ one time sensor value” ,
“history values, for the last one week” etc  ..?
Can you provide a good doc to understand the opennebula Architecture ..?

Re: [one-users] ebtables does not give anything

[Jaime Melis]

Hi Fanttazio,

Could you send us a few things in order to see what's going on?
- /srv/cloud/one/var/config (remove any passwords in that file)
- set ONE_MAD_DEBUG=1 in  /srv/cloud/one/etc/defaultrc, restart OpenNebula,
relaunch the vm and send us the error that will appear on oned.log
- the version: oned -v

Regards,
Jaime

Re: [one-users] Creating OpenNebula Image from Ubunut installed in VirtualBox

[Jaime Melis]

Hi,

you can convert from VirtualBox format to RAW which is compatible with KVM
and Xen. That's actually a good technique to create VMs, to do it inside
VirtualBox and to convert the image later to RAW.

Check this document:
https://support.opennebula.pro/entries/455869-image-contextualization

Jaime

Re: [one-users] [RFC] Writing a file repository system for images, kernels, context files, and more

[Ruben S. Montero]

Hi Viven,

You proposal is very timely indeed. We've previously discuss the need of
including (and somehow linking as an image) kernels and initrd files for Xen
deployments. Also, as  result of the security problem with context it is
clear that opennebula should check access control for context files.

Our initial designs are in line with your proposal, and basically includes:

1.- Reuse of the Image Repository (greatly improved in 3.0)
2.- Reuse of the ACL and user/group mechanism in 3.0
3.- Extend image attributes to refer file in the repository

About 1
KERNEL or CONTEXT files are defined as a new TYPE in the Image Repository.
The specific behavior of each new type could be easily tuned in the image
drivers

About 2
Specific permissions on files would be handled by the image repository, so
access control will benefit from all the new Auth system. You could share
kernels in a group of users for example, made them public...

About 3
The benefit of doing this in the OpenNebula core is that a VM will be reject
at creation if it tries to access a kernel or context file without
the appropriate permissions.

So basically we were thinking more in a coupled (in the OpenNebula daemon)
implementation.


Cheers

Ruben

Re: [one-users] Does OpenNebula work or replace VMware vCenter?

[Tino Vazquez]

Hi Derrick,

Support of vCenter is generic, integration of vCenter and OpenNebula is done
through the libvirt interface, so the functionality supported is pretty much
limited to the ESX functionality (that is deploy VMs and control its
lifecycle), but at the moment you cannot access specific licensed features
(although this is definitely in the roadmap, I cannot give a timeframe)

With OpenNebula 3.0 you will have the ability to flexibly manage different
hypervisors with an open source platform and with the ability to
perform multi-tenancy and to offer the cloud through cloud APIs, and you can
maybe rely on vCenter meanwhile to support the licensed features.

Regards,

-Tino

[one-users] Running VMs = -1

[Aleksandar Draganov]

Hello everybody,

I am running ONe on 2 hosts both with Scientific Linux 6. Host 1 holds 
the front-end, but I also want to run VMs on it.
I added, restarted, deleted some number of VMs while playing with ONe 
and at some point I got this:


-bash-4.1$ onehost list
  ID NAME  CLUSTER  RVM   TCPU   FCPU   ACPUTMEM
FMEM STAT
   3 host1  default   -1400392500
7.6G  7G   on
   5 host2  default0400400400
7.6G7.3G   on


As a result from this I can not delete host1. Is there some way to force 
it?
I am using KVM. I was also playing a bit with virt-manager - could the 
problem be from this?


Cheers,
Sasho

What does oned.log say from the monitoring of host1?
And what does onevm list say about which VM's it thinks are running where?

on


As a result from this I can not delete host1. Is there some way to force it?
I am using KVM. I was also playing a bit with virt-manager - could the 
problem be from this?


Cheers,
Sasho

Re: [one-users] Running VMs = -1

[Carlos Martín Sánchez]

Hi,

This very same problem was discussed a few days ago [1], follow that thread
to force the host deletion.

Steven, the running VMs counter is not a monitoring value, it is managed by
the core. Each time a VM is deployed, shutdown or migrated the counter is
updated.

Could you please tell us what OpenNebula version (oned -v) are you using?
Do you remember what operations did you perform? If you keep the log, we'd
appreciate if you could send it to us, off-list if you are concerned about
privacy.


Regards,
Carlos.

Re: [one-users] XML interface to open nebula

[Héctor Sanjuán]

Hi,

I don't fully understand what you are trying to set up.

Shorty said, OpenNebula will help you to deploy an infrastructure of
physical nodes which are able to run Virtual Machines on demand, using
certain hypervisors (kvm, xen...).

Im not sure what you mean by "virtual sensor cloud" nor why you want to
pass XML sensor data to OpenNebula. It sounds like you are trying to
offer a cloud-based software service (SaaS, end-users collecting info
from a cloud). OpenNebula works at a lower layer helping you manage
physical hosts and virtual machines, not the specific way a service
communicates with its clients.

There is documentation about the ONE architecture here:

http://opennebula.org/documentation:rel2.2:architecture

and a lot more about everything else on the website.

Perhaps I missed something and you can explain better,

Hector

Re: [one-users] About OpenNebula 3 and Open vSwitch (Network Isolation)

[Jaime Melis]

Hi Florin,

yes, it does. If you don't have an infrastructure that supports forwarding
VLAN traffic you may want to check out the ebtables hook.

Regards,
Jaime

[one-users] Long Running Servers

[Richard Palmer]

Dear list,

To setup a long running server I assume I need to create a specific
template file for it something like this:

NAME = long-running-server-name

...

DISC = [ source = "/path/to/disk/image/for/this/server/only.img",
 save = "yes",
 
   ]
NIC = [ IP = "XXX.XXX.XXX.XXX" ] # Fixed IP for this server
...

to ensure it keeps its state between restarts. Is anything else
needed ?.

regards,

Richard

Re: [one-users] Running VMs = -1

[Aleksandar Draganov]

Hi Steve, hi Carlos,

VMs stay in pending mode, so not allocation(this is propably another 
problem) takes place:

-bash-4.1$ onevm list
   ID USER NAME STAT CPU MEMHOSTNAMETIME
   25 oneadmin   one-25 pend   0  0K 00 00:47:58
   26 oneadmin   one-26 pend   0  0K 00 00:28:17
   27 oneadmin   one-27 pend   0  0K 00 00:01:14

There's nothing interesting in oned.log - only several methods 
invocations and successfull monitoring of the host1...


I should probably share that I have mounted /srv/cloud/images and 
/srv/cloud0/one/var with folders on other drive(I needed more space) 
which at least for the front-end(host1) worked yesterday.


The version of ONe I am using is 2.2. Unfortunately I can't reproduce 
all the operations I have performed, but I only delete/restart/shutdown 
VMs and enable/disable hosts with the sunstone GUI and I only submit VMs 
through the command line if it makes any difference. If you need some 
specific log file I can send it to you. I also reinstalled libvirt at 
some point today.


Cheers,
Sasho

[one-users] VM stuck in "migration" state - migration never issued (Xen)

[Thomas Knauth]

Hello list,

I am experiencing very long delays (>15min) between issuing $ onevm
livemigrate ... and the actual migration taking place. Which parts of
ONE are taking part in the decision when to migrate?

The log file of the VM says

Mon Jun 27 17:33:57 2011 [LCM][I]: New VM state is MIGRATE

but nothing happens. Migrations do work in general. Sometimes. When it
does not work, the
command "xm -l ..." (using Xen) is never executed on the host the VM
is running on (as can be confirmed by looking into /var/log/auth.log).

Which parts of ONE are involved when I issue the "onevm livemigrate"
command from the console? Where can I get more debug info to
troubleshoot the problem?

Thanks in advance,
Thomas.
