[one-users] vm and SUSE 10.3 HA

[Sam Song]

Hi forks,

Is there anyone configure a SUSE 10.3 HA cluster on two vms started
by ONE 4.0. The ds mad is fs, tm mad is shared, vm mad is kvm.
I am not good at SUSE HA configuration, but in my opinion, the
biggest challenge is how to share states between two vm which can only
attach local disk(one disk can't be attached to to vms at the same time).
Any suggestions?
Thanks in advance.

Sam

[one-users] VMware stay in error when added

[George Varnfield]

Hi ,

 

I'm new to opennebula and I installed ver 4.2  on a Centos 6.4 Machine
following the VMware-based OpenNebula Cloud quickstart guide but using mysql
as the database backend.

 

Net result is that I got oned sunstone up and running fine however when I
add the esxi host via the command line it stays  in error: see below

 

 

 

-bash-4.1$ onehost list

  ID  NAME   CLUSTER  RVM
ALLOCATED_CPU ALLOCATED_MEM   STAT

   5   10.254.254.139  -  0

Re: [one-users] Shutting down a VM from within the VM

[Nistor Andrei]

Hi Ruben,

Do we really care if the VM was shut down from the inside or not? I was
thinking of a hook script like the following:

#!/bin/bash

VMID=$(echo $1 | cut -d- -f2)

if [ $2 == "stopped" ]; then
  onevm shutdown $VMID
fi

It's obviously just a big fat (untested) hack, which will probably backfire
when you use onevm poweroff or onevm stop.

Anyway, the point is that we can use those hooks to notify oned that the VM
is shut down. Then oned can decide if the shut down was initiated by the
user via onevm {shutdown,poweroff,stop}, in which case it would take the
appropriate action. If it wasn't initiated via onevm* commands, but was
initiated by the guest itself, we can take some configurable action -- shut
it down for batch jobs, or power it off for say... hosting customers.

Cheers,

Andrei

[one-users] OpenNebulaConf 2013: Recordings, Presentations and Pics

[Tino Vazquez]

Dear OpenNebula users,

A very good atmosphere was created and breathed by all participants at
the OpenNebulaConf 2013 [1] last month in Berlin. Hugely interesting,
techie chats were held all over the place in small groups, with people
taking the chance to explain how do they use OpenNebula in their
infrastructures to build the IaaS layer that they want, not the one
that the Cloud Management Platform imposes. That is the great thing
about OpenNebula’s modular architecture.

So if you want to remember the great ambient of the conference, or if
you haven’t got a chance to attend, here is your opportunity to
(re)visit the knowledge shared in the conference in the form of
recordings [2] of the keynotes and talks. Also, you can check out the
presentations [3] of the speakers if you want to consult a particular
detail that you do not quite remember. And, to make the experience
even more immersing, scout through the conference pictures [4].

All the above is great, and you will feel almost as if you were there
if you didn’t. And we say almost because, as CentOS project director,
Karanbir Singh, said [5], the real value of a conference is what
happened behind the scenes, between talks, during the fantastic
evening event.

So, if you liked what you just saw, make sure you **save the date for
2-4 December, 2014!**.

(images) x (CPU/memory specs) starts to get large and requires continual

If there were quotas on templates and/or if user templates were somehow
hidden then it might be feasible to let users create their own templates
and ignore them.


Ok, so I think the only functionality missing in the new cloud view is
selecting a network. In the OCCI self-service you can define CPU/MEMORY/...
in the file based templates, in the cloud view you can do the same thing
but using OpenNebula templates instead of files. This allows you to use
restricted attributes and define different base templates for different
users/groups. In the OCCI-ss, when you create a new compute (vm) you select
an instance_type, storage and network and a new vm is instantiated using
this information. In the new cloud view, when you launch a new vm you
select a template (former instance_type) and an image, the information is
merged and a new vm is created, but you don't have to create a new
template. Therefore, I think the only piece missing is selecting the
network when the vm is launched.



 There is also the question of human resources in providing support for
OpenNebual users. Switching from the OCCI GUI requires retraining of
support staff. On the other hand, the view model will clearly be more
flexible in the long run and will facilitate provisioning for more
sophisticated users who can be trusted not to create large amounts of
templates.


I agree.



 In the meantime we have pointed the 3.8 OCCI GUI at the 4.2 core and
everything looks good so far. The only change we had to make was to
explicitly specify the OS parameters (BOOT and ARCH) in the stub templates,
otherwise the VMs wouldn't boot.


The 3.8 OCCI GUI is not tested on top of one-4.2 but it should work.



 I'm not sure I follow you suggestion below as to how cloud users could
install from CD. How would they specify a different boot device?


Specifying multiple boot devices is not supported in one-4.2, but it is
already implemented for 4.4
http://dev.opennebula.org/issues/538



 One new feature that we would find really useful would be if users
were allowed to CLONE to a different datastore. We tend to put our system
images and any public images in datastore 1 and user images in other
datastores. We have to run multiple versions of the OCCI to direct
different classes of users to different datastores. It would be nice if
users could clone from public images in datastore 1 into their own
datastore. I guess AppMarket is the proper way to do this, but simple
cloning is easy.


Indeed, there is already a feature request in our dev page for that
feature, maybe we can consider it for upcoming release:
http://dev.opennebula.org/issues/1696

But, as you said I think the best fit for your use case is using the
AppMarket component, you can host base images for your users and they will
be able to import them to their datastore.

Thank you for your feedback

 Gerry

  You could enable the images tab, as you did in another thread, so users

can
create their own images and in the "launch" vm button they will be able to
select those images and one of the predefined templates, which includes de
cpu, memory, network configuration.


  Also, without the ability to create templates I cannot see how they

can
create a datablock and install their own images from CD. I can enable
templates in the cloud view but as they are not controlled by quota I'm
worried about not being able to access our sysadmin templates among an
unbounded clutter of user templates. If the user templates could be
stored
somewhere else or hidden from view that might solve the problem.

  You can use the base template, instantiate a new vm and then attach a

new
disk (datablock) where users will install their own images from CD.

I don't really get what you are trying to accomplish, could you please
explain your use case, so we can see if it fits in the new cloud view

Re: [one-users] Shutting down a VM from within the VM

[Ruben S. Montero]

Hi Simon + Nistor,

We've done some tests in the stock drivers when the VM is shutdown (from
inside) the VM disappears from the list, show we cannot get the state (not
even with --all). How do you get the paused state?

On the other hand, the libvirt hook seems a good approach, since we could
create a file in the VM directory (e.g. .shutdown-inside) and report the
state accordingly. However we made some tests and there is no difference
between the two.

This hook:

#!/bin/bash

echo "`date`: $*" >> /tmp/hook

Gives the same in both cases:

Thu Oct 10 11:27:56 CEST 2013: one-17 stopped end -  < shutdown inside
Thu Oct 10 11:27:56 CEST 2013: one-17 release end -
Thu Oct 10 11:33:07 CEST 2013: one-17 prepare begin -
Thu Oct 10 11:33:07 CEST 2013: one-17 start begin - < boot
Thu Oct 10 11:33:07 CEST 2013: one-17 started begin -
Thu Oct 10 11:34:02 CEST 2013: one-17 stopped end - < shutdown via
libvirt
Thu Oct 10 11:34:02 CEST 2013: one-17 release end -

So, the real problem is how to determine if the VM has been shutdown from
inside or not

Cheers

Ruben

Give it a try with the ttylinux images, those are the smallest ones. The
image should change the status after the SOURCE (see oneimage show) file
reaches the image's SIZE.
