Re: [one-users] Interest in developement as a student
Hi Varun, The information about how to contribute to the project is located at [1]. If you are looking for a mentored development, you may be interested in Google Summer of Code [2]. We didn't enter the organizations list this year, but we hope to make it the next one. Regards.

Re: [one-users] [Beta 3.0] Sunstone-Server error on starting
Hi, now I tried with two VMs on the same host, but I can ping from VM to VM ... This looks like the Hook doesn't work. I also have a talk to some IPTABLE experts they think that this isn't working because the ICMP drop is based on Network Layer 3 and IPTABLES is working on Layer 2... They said that it will make sense when it is integrated into EBTABLES but not in IPTABLES. Next issue on this is, when I restart the Cluster-Node / Host-Node or IPTABLES-Service all rules are deleted this is very ugly... There should be a mechanism to integrate those rules by starting one (maybe out from database) or something else!

Re: [one-users] [Beta 3.0] Sunstone-Server error on starting
Hi, ICMP is working at layer 3, and is one of the IP associated protocols. So IP-table, is the right filtering technology, ebtables is mainly for the link layer. Could you confirm that there is no other program setting fw rules? Also could you check a ping from other host (a vm in other host or from other physical host)? Regarding iptables rules backup, it can easily included in the hook. However, these rules are VM specific and it wouldn't make sense to restore the rules and not the associated VMs upon a host restart.

[one-users] OpenNebula SelfManaged User interface
Hi Team, Does open nebula has a user interface apart from Sunstone, which provide self managed features as in EC2. I need following to be done by the private cloud users, that is whenever they need a new machine, * They login to OpenNebula interface and select the operating system (It can be Window, RedHat or CentOS) which they need and select the Memory and CPU Power, then just by clicking single link or button machine get created to them and they could access it. My users won't know on which machine that he is going to deploy or to select whatever machine which has less load. Further, he might not be a technical person to understand and create current template, he might just know OS name and following quick easy step he should be able to deploy and get what he needs. Does open nebula has the capability to look at the current setup (Network , hosts, disk space) and figure out on which machine to deploy. (Self Manageability) OpenNebula is giving fantastic features and I really enjoyed it. if there is self managed user interface that will be great to have! Please let me know where to look for...
