[one-users] Disk order meaningful ?
Hello gentlemen!
It seems that in OpenNebula 2.2 these two snippets ov a VM template are not
equivalent
-[1]
DISK = [
TYPE=fs,
SIZE = 128,
FORMAT = "ext3",
TARGET = "hdc"]
DISK = [
SOURCE = "file:///home/oneadmin/one-images/swap.qcow",
TYPE=swap,
SIZE = 200,
TARGET = "hdd"]
DISK = [
IMAGE = "venuscdebianbase",
TARGET = "hda"]
-[2]
DISK = [
IMAGE = "venuscdebianbase",
TARGET = "hda"]
DISK = [
TYPE=fs,
SIZE = 128,
FORMAT = "ext3",
TARGET = "hdc"]
DISK = [
SOURCE = "file:///home/oneadmin/one-images/swap.qcow",
TYPE=swap,
SIZE = 200,
TARGET = "hdd"]
Both declare a swap area, a file system image and a registered os image.
But the with the declarations as in [1] the machine does not boots
since it seems it tries to boot from the wrong disk.
Does OpenNebula 3.x have the same behaviour?

Beware of the clustering software, be sure to use a very recent

I tried it with an older, broken version of the clustering software and
initially it worked wonderfully well... Until the cluster software began
to malfunction and kick the servers out.
But we plan to use something like this in the future (since we have
sysadmin much better than me available :) ).

There is nothing weird.
If you do not edit /etc/sysconfig/network-scripts/ifcfg-eth0 it will
always have the wrong MAC.
The MAC is passed correctly to the vm, and if you issue the 'ifconfig
eth0' command you should see it right.
I think that the toy VM 'ttylinux' has a nice script that can be used
to generate network configuration scripts from the context.sh and the
right time to run it is NOT rc.local but before /etc/init.d/network,
placing a S09context before the S10network in the default runlevel
directory: you get the default runtime from /etc/inittab (usually
'id:3:initdefault:' for full multiuser w/o X11, 'id:5:initdefault:'
for full multiuser with X11) and the corresponding rulnevel directory
is /etc/rc[runlevel number].d .
Placing the network configuration in rc.local *may* have the effect of
some network service not properly working because they started when
the network was misconfigured.

[one-users] Again a question about the use of Java
Hello gentlemen!
Let's assume that I have an OCCI server that controls OpenNebula with
OCA (the OCCI accepts OVF messages, that's why I don't use OpenNebula
own OCCI).
Let's assume that users are authenticated by means of a client
certificate in an HTTPS connection.
How could I create an OCA Client object whith the informations I have
in the certificate?

Sorry, I do not get you. The Client class in Java OCA wants an user
name and a secret in version 2 and also in version 3 if I am not wrong.
Take a look at the javadoc: both parameters can be null, or you can use
the constructor without any parameters:
http://opennebula.org/doc/3.0/oca/java/org/opennebula/client/Client.html#Client%28%29
Thank you!
I know how Client class works, and you just confirmed me what I knew. I
will have to keep basic authentication and build up a "local password"
look-up for user already authenticated by their certificate.
That means that either I kill Sunstone or I hack it to do the same kind
of authentication: I don't want these "local passwords" go around the
Internet, or else I was not going to use certificate authentication.
"local password": something I choose and remain within our server(s).
The user has her cert to authenticate herself.

[one-users] Binding VMs to clusters, maybe on a per user policy
Hello gentlemen!
I know that OpenNebula has REQUIREMENTS that can bind a VM to a
certain cluster.
But I have this problem. We will allow users to create VMs using an
OCCI+OVF implementation Engineering is writing for the Venus-C
project. At first I thought that adding the requirement on the fly
would have done the work since I needed to redirect the all the VMs
created with OCCI+OVF to a single cluster, but this could be a bad
choice for general usage, so I started wondering if there were already
hooks to get the scheduler choose the right cluster for a certain
user ? Or should I use Haizea ?

Re: [one-users] kvm import
Sure! Just write a template with the right infos for disk images, memory size and assigned CPUs. For the network part, assign the current MAC & IP addresses, or just omit the IP, let oned choose one & ignore it, but you must take care not to use an IP oned may still assign to another VM that honors OpenNebula decisions, i.e. through context or DHCP. Please read OpenNebula documentation about VM templates. -- Gian Uberto On 19.08.2011, at 19:58, Jeremy Knapp wrote: > Is there a way to import an existing kvm vm into opennebula? > > Thanks, > > Jeremy > ___ > Users mailing list > Users@lists.opennebula.org > http://lists.opennebula.org/listinfo.cgi/users-opennebula.org > ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Some distributions do not create the simlink /usr/bin/kvm ->

Then check for the kvm kernel modules and finally check if RH default

[one-users] OCA XML-RPC output
Hello all,
I am writing an OCCI implementation that accepts OVF for the
Venus-C research project. This implementation parses OVF and
uses the extracted informatios to build the input fir the
appropriate OCA api.
/compute works using OCA allocate(), now I am working on
/compute/[id] that will use OCA info(). This call returns an XML
that I have to translate into an OVF.
I choosed to parse this XML using xjc to compile xsd definitions
into Java classes.
I downloaded the xsd from the hyperlink in the XML-RPC page, but
the definition for VMs (i.e. the answer of the info() OCA api)
is too coares, and I need to parse at least some of the tags
inside the tag to get finer grained informations.
So I have to change the xsd I downloaded.
This lead to this question: May I assume that tag order is fixed
inside ? so that the content may be defined by a
?
And does this hold even for the content of , and
?
Common sense says that Ruby should not execute its instruction
out of order, so the order is fixed and some elements may or may
not appear, but the order should not change. Can you confirm
this ?
Thank you in advance.

libvirt, when your kvm modules are not properly set, will tell you

[one-users] A Libvirt issue (again)
Some time ago I sent a post about migrations failing due an "error:

Someone said it was due a too large context and a known bug in
libvirt. I don't know if a 55M context is large, but is a
solution/workaround know for this problem ?
The most annoyng thing is that 4 out of six nodes work perfectly, the
remaining 2 where added recently, allow virsh connection in both
directions but both give this error attempting any kind of migration
:(.

TV> Nice!! If I may ask, with which hypervisor?
KVM.
As I said elsewere, clusters can become unstable without a fencing
device (and possibly without a proper sysadmin), but this is **totally
outside** OpenNebula or libvirt responsibility.
When you have a good cluster yuo could achieve better performances.
OpenNebula team could start thinking about supporting directly an even
better solution, the clustered lvm (that's under clustered gfs anyway):
Bot front end and nodes see the same clustered volume group through
iSCSI/fiberchannel andthe frontend governsremotely the
mounting/unmounting of the logical volumes during migrations and
logical volumes distructions.
This does not cover ALL the LVM usages, but for sure covers the most
useful configuration for a clustered volume group on a SAN.

Beware, there could be problems there due the presence of clustering
software that show problems without a proper fence device (and
possibly a proper sysadmin :) ).
** But this is not bound to OpenNebula at all. **
There is nothing that says that the NFS driver can't work: in both
situation user programs and shell scripts see a directory in the file
system and, as far as the userland programs are concerned, these are
simply directory in the file system. And as far as I know OpenNebula
tools are (fine) members of the userland.

I have to disable this installation in the near future and could

OpenNebula does need libvirt running, and require a proper
certificates setup to handle live migration (at least with the NFS
drivers).
libvirtd (d is for daemon, that is the libvirt daemon[1]) is started
either issuing
/etc/init.d/libvirtd start
-this is the old way, works always- or
service libvirt start
-a new, windowish way. requires the service command -
I admit that the chkconfig command is really useful for (de)activating
the automatic start of a daemon ad boot time.
[1] in Unix jargon a daemon is a program that runs in background
without a controlling tty. Windows call such programs 'services'. Unix
wisely knows that the service is what the daemon offers :).\

[one-users] Suggestions for parsing OCA output
Hello All!
Does someone has any suggestion about how to parse the results of
the OCA methods ? Did I lost some xsd I can use to build the code to
parse these strings ?

About the image: ftp://ftp.eng.it/out/quickposta.tar.bz2
This is an URL to a vm (raw, not qcow) with a toy mailserver, feel

Documentation for the toy mailserver is available on request, but it's
in Italian. The VM was made by my wife to help coders in writing

[one-users] Java OCA: poor choiche of Exception class
Hello, I just started to use OCA and immediately had the bad surprise
to find an "Exception" thrown by Client class instantiation.
Peeking in the code, I discovered that the Client class throws it when
it does not find two mandatory resources, the $ONE_AUTH file and the
SHA-1 algorithm.
In my (not so) humble opinion, the use of the raw Exception is not
meaningful enought, the use of a OneSetupException would have add NO
testing or correctness complication and could be more useful for the
coder.
Furthermore, I think these are Errors, not Exceptions since you have
no way to recover from one with a try/catch, you have to stop the VM,
correct the setup and restart.
Should I fill an update request/provide a contribution or there's no
chanche that this will enter in the code ?

Yes. Or a REST server. In this way the same client program can contact
different OVF servers with different technologies.
I think that this is better than the other solution, to use the
network awareness of the occi commands and to wrap it in a java
executable: or you do a wrapper that detects which program to wrap to
contact which remote server or you force the user to use different
clients...

[client] ---> WS ---> [ OVF wrap (java) ] ---> exec'n'wait ---> occi command
Client could be a java application, a shell script, a c program, an

I think the problem does not exist, IMVHO, since you can call ruby
from Java either by building a REST proxy or invoking occi commands.

The "-bash: no: command not found" was an _expected_ error, the above
example was a quick test meant to test the return code of the program
(that is clearly non 0), while
/usr/bin/occi-network:201: uninitialized constant REXML::Formatters
(NameError)
was not :).

[one-users] hypervisor name error
Hello, I just set up a frontend using the opennebula-2.0-1.i386.rpm to replace
the previous frontend that worked perfectly on a 64 bit xeon.
I noticed that in building the name for the remote scripts, it uses '-t'
instead of 'kvm' as in the following log lines:
Message received: LOG - 8 bash: /tmp/one/vmm/-t/deploy: No such file or
directory
furthermore i see this message occurring several times in the logs:

There could have been a problem with the license if the Mozilla
P.L. was clashing with others in OpenNebula, but it is not the
case. And we will not use other parts that require explicit permission
from telefonica.
Why Claudia ? Because we can obtain the code from within the project
and not have to write it. I am a bit sorry to be forced to say this,
but I am a bit busy lately: after 10 years as a developer I was
rocketed in the "head sysadmin" chair for R&D, and there is some mess
to clean up :).
I had no time to explore other solutions :(.

[one-users] OpenNebula & cluster LVM
Hello there!
I have some machines that all access the same clustered volume
group hosted by a SAN.
LVM driver say they do not support migrate and stop, but in this
situation the image should not move, at most one machine umounts the
lv and the other mounts.
In this situation, which could be the best "patch" to the
.../tm_commands/lvm/tm_mv.sh driver script in order to support
migration and stop in this specific case ?
Thank you in advance.

Limitations confirmed :(.
Anyway, I would work with a clustered volume group, that is every node
sees the same VG, and that is very close to NFS case where everybody
see the same thing.
Is it safe then, to assume that tm_mv it's a no op ?
I would like avoid using a distributed fs and keep my VMs on a logical
volume, and since all nodes share the volume group, migration and
stopping should be a no-op... Or am I wrong ?

Re: [one-users] VM IP address
There could be several reason for your problem. - The vm could fail to read the context correctly, therefore does not bring up the nic or does not do it with the right IP (use VNC to check with ifconfig). Even if OpenNebula allocates the IP, is up to the VM to transform the context into a network configuration. - There's nothing routing the traffic to the VM even if it gets correctly the IP from the context. This is a problem in the network configuration of the nodes running the VM.

Re: [one-users] Problem with my own VM opennebula
Quoting "CLABAUT, Emmanuel" :
ok so I need to set up a dhcp server on my front end ?
Because when i make a onevm show of my vm, i can see its ip address
You see the IP that OpenNebula as leased, but it did not do it with a
DHCP server. The virtual machine itself does not know anything about
that IP address

You should provide a DHCP server or change the image so that, at the

What appens is that, for what I understood:
The contextualization infos(*) are automatically inserted in a shell

mounts.
(*) you do not need a "context" section in your vm definition, network
values come from the network you defined.
This script contains some variable definition, one of which holds the
IP address leased to the vm; a script in ttyLinux will source this
file and create the redhattish sysconfig/network-script file that will
be used when the /etc/init.d/network start command is issued by init -
throught the symbolic link in one of the rc(runlevel).d.
