[one-users] Problem Login/ssh into vm

[Alexander Sibetheros]

I recently set up a simple 2 node opennebula(ubuntu/kvm) (using vmware
vm's), following the tutorial.

I got a centOS vm to run, but cannot log in.
I read on other sites that login in is done via ssh and not vnc, but
whenever I ssh root@..vm_ip... I get prompted for password which I dont
have.


I followed this step from the tutorial(before running I ran ssh-keygen -t
dsa, because the id_dsa.pub file did not exist):

In order to dynamically add ssh keys to Virtual Machines we must add our
ssh key to the user template, by editing the user template:

$ EDITOR=vi oneuser update oneadmin

 Add a new line like the following to the template:

SSH_PUBLIC_KEY=ssh-dss B3NzaC1kc3MAAACBANBWTQmm4Gt...

 Substitute the value above with the output of cat ~/.ssh/id_dsa.pub.

Unfortunately no..

Re: [one-users] how can i monitor the vms ?

[Tino Vazquez]

Hi,

The Ganglia drivers are now an add-on [1], that can be found here [2].

In any case, OpenNEbula doesn't need Ganglia to monitor VMs and physical hosts.

Re: [one-users] Virtual Machines High Availability

 Hi

 I’m reading VM HA (
 http://docs.opennebula.org/stable/advanced_administration/high_availability/ftguide.html
  )
 and have a question about Actions.
 The document lists two possible Actions:

 -r (recreated)
 -d (delete)

 What does –r exactly do?
 Is VM restarted on available host using existing disk(s) on shared storage?
 Or is it recreated and previous state discarded?

 --
 Thank you,


The -r option corresponds to the onevm delete --recreate action. The disks
will be kept only if they are using a persistent image on a shared storage.
Any other disks are deleted.

Take a look a this recent thread for more information:

Re: [one-users] Front-End node

[Carlos Martín Sánchez]

Hi,

 wrote:

 (already in one cluster???)

The installation of OpenNebula itself will be the same for a physical and a
virtual machine.

One thing you need to keep in mind is that OpenNebula assumes full control
of the hosts. This means that the scheduler will think that all the memory
and cpu of the host is actually available to opennebula VMs, and you may
end overcommitting the host running your front-end VM. This may or may not
be a problem for you; if it is you can tune the scheduler configuration
(hypervisor_mem) [1].

 And can onenebula manage yourself (manage the vm installed in node)?

No, OpenNebula will report a wild VM inside the host. The VM will not be
destroyed or managed in any way, it will be simply ignored.

 OpenNebula Frontend in a VM It can be done, but how well it performs
 depends on what data store you
 are using.  We do it in our development OpenNebula cloud but not
 in production yet because we are using a shared image store with
 GFS2 and CLVM and it is difficult with our current situation to
 get a VM to be a member of a cluster like that, particularly since
 our fibre channel host bus adapters don't support pass-through.
 We are exploring other options for our data store as we migrate to
 OpenNebula 4 series so we can make it work more smoothly.

 With NFS data store or ssh-based data store I expect you would not
 have any problems.

 So right now in the meantime our high availability OpenNebula head nodes
 run on bare metal, in an active-passive configuration,
 using Red Hat Clustering to manage the high availability of the service.
 HA is not perfect--if one head node goes down while a VM operation is in
 progress, the other one will not pick it up, but it's good enough for
 most thiings.

 There was a High Availability guide recently published.

 http://opennebula.org/documentation:archives:rel4.2:onehaWe were doing most 
 of this stuff in version 3 before it was formalized in
 the guide.

Re: [one-users] Upload image and use ubuntu12 iso locked problem

[Daniel Molina]

Hi Alexander,


On 17 December 2013 09:35, Alexander Sibetheros alexsib...@gmail.comwrote:

 I am having problems creating an image via sunstone, using a path to
 ubuntu12.4.3 server iso, and also creating a template afterwards.
 I have 2 vm's(on vmware player) running that have ubuntu/kvm controller
 and node.
 Installation was based on tutorial.
 From the tutorial I was able to get a CentOs running(although I don't know
 how to find username/password...), but when I try to create image based on
 path of iso I get locked status. I can see the image in my list though
 and no errors during creation.
 I chose not persistent and driver:raw, but am unsure what I should
 choose.

 Any advice and any good documentation/tutorials/faqs for image uploading?


The image will stay in locked state until the file is uploaded and copied
to your datastore, so if it is a large file, it can take several
minutes/hours depending on your connection/io

Cheers

I assume you are using this image from the marketplace:
http://docs.opennebula.org/stable/administration/references/schg.html#configuration

Maybe the problem is a wrong syntax in the VM template. Can you paste its
contents?
It should follow the syntax described here:

Re: [one-users] Hybrid Cloud (OpenNebula + Amazon EC2)

 Hi all,

 I would like to ask some questions, it might sound silly but here goes;

 1. I have very little knowledge about hybrid cloud, so I watched this
 youtube video [1] and the question is, the VM that was instantiated is
 resides on EC2 or OpenNebula?


In that video the vms are instantiated in OpenNebula using the EC2
interface. The use case you are looking for is a cloudbursting scenario,
you can see an example in the following video, where the VMS are
instantiated in Amazon using OpenNebula:
http://www.youtube.com/watch?v=v76FTfglhIs



 2. If the VM is on EC2, is it free or I have to pay per use? Also can I
 accessed it from anywhere (public cloud) provided I have Internet
 connection?


It depends on the instance-type/ami.. you are using, you should check the
Amazon pricing.



 3. As far as I know, EC2 use .ami image. Do I have to convert my image
 from .qcow2 to .ami?


You can use any of the available public amis in Amazon or upload your own
one.

Cheers



 Thank you

 Best regards,
 Fazli

Before creating the vm I added the ssh parameters to the user:
$ EDITOR=vi oneuser update oneadmin
Add a new line like the following to the template:
SSH_PUBLIC_KEY=ssh-dss B3NzaC1kc3MAAACBANBWTQmm4Gt...
Substitute the value above with the output of cat ~/.ssh/id_dsa.pub.

 I assume you are using this image from the marketplace:

 Maybe the problem is a wrong syntax in the VM template. Can you paste its

 It should follow the syntax described here:

Re: [one-users] Errors, problems when creating VM using OpenNebula 3.6.0 in Ubuntu 12.04 with iSCSI datastore

[Jaime Melis]

Hi,

you should never use SOURCE but PATH. Can you try again with:

NAME = Winxp-iscsi
PATH = /var/lib/images/win-xp.qcow2
TYPE = OS
PUBLIC = YES

Cheers,
Jaime

 Dear Jaime (and the OpenNebula Community members),

 Thanks for your reply.

 I will upgrade to OpenNebula 3.8.1/5 to see how it will go.

 1) when run oneimage show 0, it should have below output:

 ..


 SOURCE: iqn.2013-12.iSCSIHost:192.168.1.7.vg-one.lv-one-13
 PATH: /var/lib/images/win-xp.qcow2

 ..

 but it have below output:

 ..

 SOURCE: /var/lib/images/win-xp.qcow2.

 ..

 For the above result, the image template file winxp.img is defined as
 below:

 NAME = Winxp-iscsi
 SOURCE = /var/lib/images/win-xp.qcow2
 TYPE = OS
 PUBLIC = YES

 Image creation command is oneimage create winxp.img -d 100. 100 is the
 ID of in iSCSI Datastore.

 2) In the winxp.img, change the SOURCE to PATH, create the image again,
 then when run oneimage show 0, the result is different, as shown below:

 ..

 SOURCE:
 PATH: /var/lib/images/win-xp.qcow2

 ..

 The error message is Error copying image in the datastore: Error
 registering 192.168.1.1:/dev/vg-one/lv-one-3

 This show it is still incorrect.

 3) Will upgrade the OpenNebula to see the difference. It is much
 appreciated if you can email me the correct information on how to Create a
 winxp VM using OpenNebula 3.x.x in Ubuntu 12.04 with iSCSI datastore.

 Thanks kindly,
 Q.S.

 Hi,

 OpenNebula 4.4 which has been just released has deprectated iSCSI. The
 main reason is that the tgt iSCSI daemon is not very flexible and we
 recommend using other storage mechanisms instead.

 OpenNebula 3.6.0 should be definitetly upgraded to newer versions.

 Regarding your specific problem, can you please detail what command and
 image file did you use to create the image?

 Dear OpenNebula Community,

 1) To create VM using OpenNebula 3.6.0 in Ubuntu 12.04 with iSCSI
 datastore, I create Front-end, NodeServer and iSCSIHost (an iSCSI target VM
 created within the NodeServer. The IP of iSCSIHost is 192.168.1.7).

 The required setup, configuration for Front-end, NodeServer and
 iSCSIHost looks fine.

 The host, image, vnet and datastore creation under NodeServer are ok
 (except of the VM creation in below 2) ), but when oneimage show 0, can't
 see output of

 the opennebula 3.6.0 used was downloaded in more than one year ago. is
 it the correct version of opennebula to use?

 so bridges variable maybe have the same name bridge. because bridge is a

  Hi everyone！

I find a problem when we create two or more instances on one host at
 the same time，we meet the error device onebr alreay exists can't
 create bridge with the same name.
The reason is that instances all try to create their bridge，although
 they check whether or not their birdge is existed. because it's at the same
 time, they all get a result that their bridge is not existed, and then they
 create it.
But when they really create, the same bridge has already been created
 by other instances.

 Has the problem been fixed now？ I use opennebula-3.8.1.

Look forward your answers!

dylan.

Re: [one-users] Ubuntu/debian repositories for 4.4

[Javier Fontan]

Hi,

Indeed the repositories path have changed to
http://downloads.opennebula.org/repo. I'll check wether I can redirect the
old repositories to the new ones without breaking anything.

Splitting the repositories by OpenNebula versions seems a good idea. I'll
also keep the separation between distribution versions, that is, Ubuntu 12
and 13. We will check the best way to do this but don't expect it to be
changed until next minor version (4.6).

Thank you for the tips

 Usually in debian I use the repository stable that is automatically
 updated to new stable version when it goes out (also testing and unstable
 are automatically updated). I never use versions names (wheezy etc.)
 So it is easier, when a new version is out I simply apt-get update;
 apt-get dist-upgrade. No need to change repositories.

  standardised on downloads.opennebula (??)

 The same here ;-)

 As an upgrade requires manual intervention, I propose to use named
 repositories per distribution:

 deb http://downloads.opennebula.org/repo/debian/7 retina main

 Using a symlink to point to stable release if required and another one
 to point to numbered version.

 I'm not sure about it but we could use the distribution name as
 component, like:

 deb http://downloads.opennebula.org/repo/debian retina wheezy
 deb http://downloads.opennebula.org/repo/debian retina jessie

 It's quite easy to configure reprepro[1] and it's incoming to dispatch
 packages.

  Hi

  The host running ONED needs to ssh to all VM hosts using public key
 (passwordless).
 ONED will use ‘oneadmin’ account to access all VM hosts.
 B/c /var/lib/one is shared (using NFS) between ONED and all hosts you
 need to setup public key auth only once for user ‘oneadmin’.

  Setup your NFS server/filer, login to ONED controller, mount
 /var/lib/one, su – oneadmin;

  cat ~/.ssh/id_rsa.pub  ~/.ssh/authorized_keys
 Chmod 600  ~/.ssh/authorized_keys

  Now, you can ssh to any host as user ‘oneadmin’ using public key.
 Please note, that each host needs /var/lib/one mounted from the same
 location as other hosts and ONED server.

  If you chose to only use NFS for your datastores (I.e.
 /var/lib/one/datastores/) then you need to add public key on ALL your
 hosts, not just one.

Re: [one-users] V4.4: Bridge Configuration/physical device attach in VLAN driver on existing bridge

[Jaime Melis]

Hi Michael,

thanks for the contribution!

I've just create a ticket to evaluate it for OpenNebula 4.6:
http://dev.opennebula.org/issues/2574

Cheers,
Jaime

michael.kutz...@virtion.de wrote:

 Hello,

 we had some problems in the past deploying VMs when a bridge interface was
 already existing (static configuration e.g.) using a different interface as
 physical than defined in the virtual network in ON.

 Example:
 - A bridge br10 was existing with a local interface eth0 attached.
 - The virtual network in opennebula was configured to use eth1.
   (due to some historical or physical reasons eth0 was used on that host
   and the bridge was „preconfigured“)

 The ON driver (opennebula-4.4.0/src/vnm_mad/remotes/802.1Q/HostManaged.rb)
 now checks the following:
 - bridge exists: no, create bridge
   This works fine as the bridge is already existing
 - device is attached?
   No, attach it (so we have eth0 and eth1 attached to the bridge interface
 afterwards)
   This leads to some small (or bigger) problems (e.g. creating a loop on
 the switches and making
   the network practically unusable).

 Attached you find a small patch which does the following:
 - bridge exists?
   Yes, do nothing
 - no: create bridge, add interface

 This will also cover the scenario that you can change the physical device
 in the virtual
 network definition after having deployed certain VMs.

 Hopefully I did it right and made the changes in the right place.

 I dont know, if anybody else had that problem, but I wanted to share this
 information.

 Best, Michael

 It's weekend, people are out of their computers (maybe).

 Are you sure sunstone server is not being started when you reboot? It
 should be as launched at startup like the one service, you could have made
 some mistake during the installation?

 That being said, I'll make a bash script which contain the lines. (This
 method is prety lame, and I haven't tested it yet)

 su oneadmin

 sunstone-server start

 Then add the script to the /etc/rc.local file. I would assume you can change 
 users without any passwords?

Re: [one-users] Problem Login/ssh into vm

[Alexander Sibetheros]

I would like to note that when I added tty-linux - kvm from the
marketplace, created a simple template(same as the centOS), and run it, I
was able to login and use the vm. So I know the host works, and my problem
most likely is in the way ssh works from the controller to vm's...

Also noteworthy, I cannot ping the vm's from the controller...only from the
host. Im not sure this is correct or not.

 I assume you are using this image from the marketplace:

 Maybe the problem is a wrong syntax in the VM template. Can you paste

 It should follow the syntax described here:

Re: [one-users] Problem Login/ssh into vm

[Jens Hoffmann]

Can you login into your vms via vnc and investigate, i.e. if ssh daemon
is running and if ssh keys are correctly inserted into your login-user's
authorized_keys?

The ping problem  may be a routing problem on your host. Check if the
host has ip_forwarding enabled such that the host forwards packages
between eth0 and br0, that is between the bridge and your host's
physical nic. If this does not help, investigate your routing tables and
try to track your ping's package flow with tcpdump.

Re: [one-users] Problem Login/ssh into vm

[Alexander Sibetheros]

But that is exactly the problem. I can access the vm via vnc(from
sunstone), but get login screen(local host login/password which I don't
know). So, I can't check for daemons. I read online that for the images
created for kvm/opennebula access is done via ssh(passwordless).

Because the image I am using is prebuilt for opennebula, I imagine
something is wrong in my controller/node configuration, but do not know
where to look.

[one-users] why does it take so long to delete kvm process (VMs) on host

[Liu, Guang Jun (Gene)]

Hi there,

I have a host with 256G ram (and 32cores). I created 13 VMs (each
requires 16G ram) first. Later I deleted all of them. I found that the
kvm processes stay there for quite a long time (~10 minutes) and the
memory was consumed by them. (so that my host started to use swap which
cause it runs very slow). I wonder why deleting these VMs on host takes
so long time. Does anyone know whether its because the low priority of
deleting vm from openNebula scheduling perspective or there is some
settings I need change?

Thanks very much!

Re: [one-users] Problem Login/ssh into vm

[Alexander Sibetheros]

I'm am writing again to clarify I fixed the 1st problem.
I was trying to ssh from the root@node instead of oneadmin@node(which I
never used before). I can successfully ssh, change root password :) Thank
you very much for your ideas.

I am not able to do such from oneadmin@controller though(controller-vm,
instead of host-vm). Ssh and ping both fail and I don't understand how
tcpdump works.
I did find that there is a problem with the way opennebula works with
ip/mac address of vm's and that a special script is needed to correctly map
them, but I don't really understand what is going on.

Specifically I found:
(1)
http://lists.opennebula.org/pipermail/users-opennebula.org/2011-December/007042.html

Using the CONTEXT cdrom, the init.sh script in executed at boot time. You
can modify the init.sh script to set your broadcast address and netmask.
You can hardcode these values, or pass them as a CONTEXT sub-attribute;
take a look at the DNS example from the contextualization guide:

(2) http://opennebula.org/documentation:archives:rel3.0:cong
Using Virtual Network Leases within a Virtual Machine

(3)
http://serverfault.com/questions/331145/bridging-virtual-networking-into-real-lan-on-a-opennebula-cluster
OpenNebula, by design, doesn't actually manage IP addresses even though
it maintains a pool of them and leases them out. What it's really
doing is assigning a MAC address to the virtual ethernet interface that
has the desired IP address encoded in the last 4 bytes of the MAC
address, and it's up to the OS to recognize that and assign an IP
appropriately.

Re: [one-users] VM in Opennebula for Openvz failed

[Catalina Quinde]

Hi friends, Nikolay especially.

I have SOLVED the issue of deployment of the MV, the virtual machine that I
made earlier in OpenVZ could deploy it on OpenNebula and must perform the
following procedure:

1. You must use the following command in the OpenVZ node:
sudo vzdump --compress --dumpdir /root/ 101

2. the result is a .tgz file to be found in the /root/ directory, the
extension of this file should be changed to tar.gz,

3. then this file is copied to FrontEnd node can be in the directory
/var/lib/images,

4. then made the image and then the template is performed and then the VM:

5. I used this template:

NAME=VMdebianm64
NIC=[NETWORK_ID=0]
OS=[ARCH=x86_64]
VE_LAYOUT=ploop
MEMORY=512
CPU=0.01
VCPU=1

RCLOCAL=rc.local
OSTEMPLATE=debian-7.0-x86_64

Thanks very much Nikolay for your help, has been very important.

You have A WONDERFUL DAY [?]

 Hi Caty,

 as I wrote you before, please, don't send personal emails, use
 opennebulausers mail list so others can also benefit on that. Opennebula
 users mail list archive is kept online. So if someone in the future will
 have the same error message as you he/her will be able to find a solution
 on the web in opennebula mail list archive.

 As for your problem, try to add SIZE subattribute (in megabytes) to DISK
 attributee.g. as below:

 Chmod 600  ~/.ssh/authorized_keys

  Now, you can ssh to any host as user ‘oneadmin’ using public key.
 Please note, that each host needs /var/lib/one mounted from the same
 location as other hosts and ONED server.

  If you chose to only use NFS for your datastores (I.e.
 /var/lib/one/datastores/) then you need to add public key on ALL your
 hosts, not just one.

  Hi,

  Please reply to the mailing list as well.

  Yes. It is a basic requirement that all the nodes (frontend +
 hypervisors) should have a oneadmin account, and they should be able to ssh
 passwordlessly from any node to any other node.

  cheers,
 Jaime

  Hi Jaime,

  Thanks a lot for your reply. I have one more doubt. Should I have to
 ssh passwordless to the frontend if I am using ssh transfer manager. I 
 know
 that it has to be done for the hosts.

 Hi Neelaya,

  the frontend and the nodes must share /var/lib/one/datastores. Any
 node can export this share, preferably a NAS system, but if you don't 
 have
 been, you can export it from the frontend.

  cheers,
 Jaime
