Re: [one-users] BOOTPROTO, DHCP_HOSTNAME, and vm IPs in Sunstone
I would definitely not prefer that the vm manage the IP. What I would like to do upon new vm creation: 1. VM gets spun up with BOOTPROTO=dhcp 2. VM gets spun up with DHCP_HOSTNAME=$NAME 3. IP given to the VM by the dhcp server on my network is then the IP that is listed in sunstone for that VM. AFAIK: 1. There is no way to achieve item 1 in ONE out of the box, I have to either write a bash script that gets run on VM spin up, or create an image that does this. 2. I can set the _hostname_ via template, but in order to set DHCP_HOSTNAME again I have to run a bash script on spin up. 3. There is no way to accomplish item 3, outside of writing a bash script that runs on my head node that grabs IP data and dumps it into the database. Certainly this is not preferable. These three items taken all together suggest that including the option to easily support DHCP out of the box would be a nice feature to have. I'm working on a bash script currently for 1 and 2, but for item 3 I am out of luck. I hope that makes sense. Let me know if it doesn't and I would be happy to clarify further.

Re: [one-users] Run bash script in vm on spin-up
Hi Valentin, I appreciate the help! I managed to create a new CONTEXT image, which copied my test.sh to the datastore successfully, and I updated my template to include those two lines you specified. However, it looks like test.sh is not executing on vm spin up. Currently all it does is touch /root/test.tmp to confirm execution. However when I booted my vm, this file was not created. Also tried doing useradd tmp as well, with no luck. test.sh has executable flag set for user, group, and other. I also tried setting permissions of test.sh to 777, still no luck. Thanks!!

Re: [one-users] BOOTPROTO, DHCP_HOSTNAME, and vm IPs in Sunstone
Javier, Thank you for your help. I am considering going with the following option (if this is possible) Run bash script on boot that sets the DHCP_HOSTNAME to the hostname, removes the NETMASK, IPADDR, and GATEWAY lines from /etc/sysconfig/network-scripts/ifcfg-eth0, sets the BOOTPROTO to dhcp, and restarts networking. I have a bash script already that will do this, and it gives the desired result. I will then simply ignore the IP listed in sunstone and deal with hostnames only. My script is written in such a way that it can be run multiple times without issue. I just need to figure out how to include this bash script and have to run automatically when a new vm is spun up, but it looks like there should be plenty of documentation on how to do this. I am unsure how to use a DHCP client to suggest an IP to the DHCP server, or if DHCP supports this. Thanks!!

Re: [one-users] DHCP
Valentin, Thank you for the help! Yes, AFAIK the DNS server is configured with a dynamic zone that is updated from the DHCP server. It sounds like the DHCP server in use is Microsoft DHCP. I would like to avoid using the DHCP API if possible, just because I have no experience in that area, and seems like a messy solution. Thinking about this more, here are the desired steps: 1. User spins up vm via web interface. 2. Contextualization sets DHCP_HOSTNAME to vm name. 3. DHCP server gives vm an IP address. 4. Sunstone sets the correct IP information in its database. I can basically do all this manually by 1. Spin up vm 2. edit ifcfg-eth0, setting BOOTPROTO and DHCP_HOSTNAME 3. restart networking So it sounds like I can write a bash script that takes care of 2. and 3., something that runs when the vm is spun up. However, I don't know how to manually tell Sunstone what the new, correct IP is. Do you know how I could accomplish that? I can write a bash or perl script that fixes this manually in MySQLbut that seems like a Really Bad Idea. :) I'm surprised that OpenNebula doesn't support DHCP out of the box. Seems like a common use case. I wonder if I should make a feature request. Thanks! Kerry On Wed, Jul 23, 2014 at 10:03 PM, Valentin Bud valentin@gmail.com wrote: Hello Kerry, When you say DNS and DHCP are tied into one system on my network you mean your DNS server is configured with a dynamic zone that is updated from the DHCP server? If that is so, I guess you want a VM to acquire a lease from the DHCP server equal to the IP given by OpenNebula to that specific VM. This way it maintains consistency. If you populate CONTEXT with NETWORK=YES, the contextualization packages will do the job of configuring the network. As far as I know it's not possible to tell the contextualization packages to leave the network unconfigured. So using this approach would not get you where you want. One way of achieving what you desire is to program a hook that inserts a host in the DHCP server via OMAPI [1]. From the hook you have access to the entire template. I am assuming you are using ISC DHCP. This would solve the consistency issue. Now the VM needs to be configured for DHCP as you mentioned in your previous E-Mail. For that you can define SET_HOSTNAME in the CONTEXT to have it available in the VM, create a simple (bash) program that reads it and sets ifcfg-eth0 accordingly. Put the script in the files datastore and update the context to use it via FILES_DS and INIT_SCRIPTS. For example you name your super script set_dhcp.sh. You can insert in the files datastore [2] using `oneimage create -d files --name set_dhcp.sh --type CONTEXT /path/to/set_dhcp.sh`. Update the template to use it. CONTEXT=[ FILES_DS=$FILE[IMAGE=\set_dhcp.sh\, INIT_SCRIPTS=set_dhcp.sh] This way the vmcontext init.d script from the contextualization packages would skip the network configuration, note NETWORK=YES is missing and it would run the set_dhcp.sh script. One more thing that comes to mind, SET_HOSTNAME would instruct the vmcontext init script to set the hostname and maybe that's not what you want, maybe you want your VM to set it's hostname from DHCP. In this case use another variable, like DHCP_HOSTNAME in CONTEXT and process it in set_dhcp.sh to configure ifcfg-eth0. You can set DHCP_HOSTNAME=$NAME inside the template. This way the name you give the VM in Sunstone would end up being used. Take the above with a grain of salt, I am sure there are other (better) ways of achieving what you desire. @Diego could you please point me where have you find DHCP in the VNET template? I have looked over the docs and couldn't find it.

From the ONE docs, it looks like I need to create a system datastore using the ssh driver. However, I have done so yet the disk images remain on the frontend node. I used Sunstone to create a new datastore with the following parameters: Name: New system Presets: Filesystem Cluster: Default (I'm not using clusters just yet) Type: system Datastore: filesystem Transfer: ssh Safe directories: blank Restricted directories: blank Base Path: /one/system (which I created on my host, and chowned to oneadmin:oneadmin) Limit: blank I also removed the default system datastore, which is a shared datastore. Expected behavior: disk images for new vms show up in /one/system on my hosts. Actual behavior: disk images show up in /var/lib/one/datastores/100 on the frontend node. (100 is the ID of my new ssh system datastore) Any help would be greatly appreciated. Thanks!!

[one-users] Changing /var/lib/one location
Hi folks, I was wondering how to change the location of /var/lib/one. I have tried making a symlink from /var/lib/one to a new location before installing the ONE packages, but for some reason generating the ssh key (and possibly other installation steps) failed. My reason for doing so is that I am working with systems that have /var as a separate 10 gig partition, and it is not something I can change. Thanks! ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

That's a good idea. Let me give that a try. Thank you!

Re: [one-users] Changing /var/lib/one location
This seems to have _mostly_ worked. I created a logical volume and mounted it at /var/lib/one, installed the opennebula packages, and then changed the ownership to the oneadmin user. However, I have noticed two issues. 1. .ssh was not created. (but all other files appear to have been created normally afaik) 2. The system data store does not report capacity. (but the files and default datastores do) My guess is that when the opennebula packages are installed, there is an if statement being run by the installer that checks to see if the /var/lib/one directory already exists, and if so, does not do certain things. (like set up .ssh, perhaps) Any suggestions would be appreciated! Kerry On Tue, Jun 17, 2014 at 11:09 AM, kerryhall . kerryh...@gmail.com wrote: That's a good idea. Let me give that a try. Thank you!

Re: [one-users] Changing /var/lib/one location
Hmm, looks like selinux was already disabled. Not sure what's going on there. I generated the ssh key manually and everything _seems_ to be working as expected. Thanks!
