Re: [one-users] DHCP and OpenNebula
Hello Christophe,
If you really want to use DHCP in combination with OpenNebula I suggest you
take a look over omshell [1].
With a simple hook you could enter the required DHCP host entry via OMAPI
and your VM will pick it up at boot.

Hello,
Is it possible that a virtual DHCP-server gives ip addresses to the
other VM's and that OpenNebula will take over this ip-address in sunstone?
Because now my dhcp gives the new VM an IP-address but in the sunstone
interface the VM has an other IP given by the Virtual Network template
can this be changed?

Re: [one-users] DHCP and OpenNebula
Hello Jaime,
I don't have a hook for that. It was an idea I came up with for this
particular use case. I don't use DHCP with OpenNebula.
Anyway, good question though. I have made a little bit of research about
OMAPI
and how can one use it from different programming languages.
Ruby:
https://github.com/pikelly/dhcpIT
http://www.ruby-doc.org/gems/docs/e/esxmagicwand-0.1.2/DHCP/Server.html
Python:
https://code.google.com/p/pyomapic/
https://github.com/jof/pypureomapi
Perl:
http://search.cpan.org/~jhthorsen/Net-ISC-DHCPd-0.14/lib/Net/ISC/DHCPd/OMAPI.pm
Bash:
http://www.jedi.be/blog/2010/12/08/automating-dhcp-management-with-omapi/(also
has a Java example)
http://comments.gmane.org/gmane.network.dhcp.isc.dhcp-server/11411
Hope it helps :).

Re: [one-users] DHCP and OpenNebula
Hello Christophe,
The best place to start is the documentation about Using Hooks [1]. Keep in
mind
that OpenNebula has the same level of quality in documentation like FreeBSD
does ;).
Whenever you have a problem check there first, 99% of the cases you will
find it there.

[one-users] Static IP Networking in Opennebula 4.6
Hi All, We have a server with 1 physical network port (eth0) and 5 static IPs for 5 different web servers. One of these static IPs is currently assigned to a bridge (br0) which is connected to interface eth0. What is the best way to map 5 vms (running the web servers) to the static IPs? I see a virbr0 bridge in ifconfig. I have a public network created with this bridge and VMs are able to talk to internet. -- Thanks, Sangram Rath ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
Re: [one-users] system datastores always have no space
The system DS is not supposed to show up with any space until a host is configured? That is a surprising because the pre-configured sandbox instance I downloaded first for testing (a Virtualbox instance) has space listed in the system DS even though that has no hosts connected to it. In any case, there are no hosts connected to the test instance that I gave the example on, but on some other instances which I have configured elsewhere do have hosts configured and they have the same problem. I have /var/lib/one as a NFS mount that is mounted on both the frontend and the node. That instance comes up with no space in the system DS as well. Here is some output from that showing the system DS with no space even though the logs say the node is successfully monitored: http://pastebin.com/w6Wg909Y -Marius marius...@venda.com On Fri, 2014-05-09 at 05:05 -0400, Carlos Martín Sánchez wrote: Hi, System DS are monitored with the host probes.

[one-users] creating a template with install cd
Hello. I'm somewhat to stupid to create a template containing to disk images. One disk iso (ubuntu install cd) and one empty block.

[one-users] VM cannot connect to outside (internet)
Hi, Virtual machine gets an IP through contextualization, however virtual machine is not able to connect to internet. Also from inside the VM, I do not see any other interface apart from lo. Is this normal in contextualization? I am able to ping the VM from same host. Host is Cent OS 6.1. Host has br0 connected to interface eth0. And virbr0. -- Thanks, Sangram Rath ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Re: [one-users] VM logs in /var/log/one dir
Yes, a hook will do. You can use the example provided here:

Hi
How do you handle VM log files under /var/log/one dir (i.e.
{ONE_VM_ID}.log)?
The ONE system is used as a back-end for VCL (https://vcl.apache.org)
which results in many VMs per day/month and /var/log/one/ ends up with
thousands of log files.
I don't thing I can use logrotate for this task. May be a VM hook on
shutdown/delete?

Re: [one-users] system datastores always have no space
I am not sure I follow what you are trying to say. What is the source of my problem? All of my datastores, which live on the same NFS mount, exist on the the monitored host. They are mounted in /var/lib/one, which matches the BASE PATH for the datastore. So I do not know how the NFS mount is not 'properly mounted.' The output I get from the command you specify is: [root@kvm04 ~]# /var/tmp/one/im/kvm-probes.d/monitor_ds.sh kvm /var/lib/one/datastores DS_LOCATION_USED_MB=1 DS_LOCATION_TOTAL_MB=1409258 DS_LOCATION_FREE_MB=1408682 So it looks the probe is finding available space. But according to the output of 'onedatastore' there is no available space. Thus no VMs can be created on my KVM host/node. I am not sure what step or procedure I am missing. I do not see anything in http://docs.opennebula.org/4.6/design_and_installation/quick_starts/qs_centos_kvm.html that I have skipped. Does it matter that the KVM node already has VMs running on it? Otherwise the node fits the guide above precisely. The plan is to put everything under OpenNebula management. But since the system DS reports having no space, I cannot launch a single VM, and thus will not be able to spin any of those machines down to bring them up under OpenNebula management. -Marius On Fri, 2014-05-09 at 15:35 -0400, Ruben S.
