Re: [one-users] Genenare VM list
Hi Carlos, Thank you very much for the valuable information. I have done the changes in onevm_helper.rb to add new column “IP” and also added into default column list, but somehow it didn’t work for me. Anything I have missed?

Re: [one-users] DHCP
As far as I understand, GATEWAY, DNS and DHCP should be variables configured on the VNET template, and appart you have to set NETWORK=YES on the vm template. Then, each time a VM is instantiated from that VM template, it will automatically populate some variables that are ETH[n]_GATEWAY, ETH[n]_DHCP and ETH[n]_DNS with the variables you configured on the VNET templated. With the only one I'm not sure is the DNS, but the other ones you can find some informaton on the user guide, and some more on the admin guide. Best regards,Diego M.

Re: [one-users] DHCP
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.

Isn't it a bug?
What is the error message that is shown in Susntone?

I have found my mistake!
It was silly - Some time ago I pressed Secure websockets connection
chekbox in configuration tab and forgot about it.
So now it's working!
