Re: [one-users] BOOTPROTO, DHCP_HOSTNAME, and vm IPs in Sunstone
The context packages are meant to be used with static networking. To add that parameters to network configuration you can do one of these things: * Create the network configuration in the base images manually and do not set network contextualization in OpenNebula so they are not overwritten. * Modify the context packages to add those parameters [1] For the third thing there is no way to do it. OpenNebula gets an IP from the network pool and assigns it to the NIC. There is no way to change it after it is selected and there is no external method of selecting the IP. What you can do is configure DHCP so it picks the same IP as OpenNebula had selected for the VM. The MAC addresses are generated from the MAC prefix and the IP, you can configure DHCP with those mac/ip pairs.

[one-users] Multiple network cards with same MAC address
Hello,
Using ONE 4.8 on two nodes with Open vSwitch networks, a crossover cable
between the nodes as trunk.
I have a router template using 4 different networks, each network is
isolated in dedicated VLAN, but 3 network cards use the same MAC
address.
On another try two of them use the same MAC address.
This result is miss-function on that router, the firt card is tagged
with the VLAN ID two times, the next one is in trunk mode:

That is, 'oneimage list' still lists, among others, disk image 292, but any further action on it, like delete or show, says [ImageInfo] Error getting image [292].

[one-users] 2014 OpenNebula Cloud Architecture Survey Results
Dear OpenNebula users, The results of this survey were collected during July and August of 2014 from the OpenNebula open source cloud management platform community with regards to the type of cloud deployment and its main architectural components. The aim of the survey is to acquire information in order to improve the support for the most demanded infrastructure platforms and deployments. Since the foundation of the open-source project in November 2007, OpenNebula has been downloaded more than 200,000 times from the project site (120,000 times since our last survey in September 2012), not including other software repositories or third-party distributions. Regarding the use of OpenNebula, the Survey shows that 42% of the deployments are in Industry and 14% in Research Centers. 74% of the organizations are in Europe, Russia or USA. 88% of the respondents use OpenNebula to build a private cloud. When asked about the type of workload, 62% said that they use OpenNebula for running production workloads. Regarding the size of the clouds, 10% of the deployments have more 500 physical nodes. 44% of the deployments consist of more than one OpenNebula zone and 4% are running more than 10 zones. One of the companies reported a workload of 200,000 VMs. Among the advanced components offered by OpenNebula, High Availability, with 67%, is the most widely used or planned to use, which is closely aligned with the top usage of OpenNebula in production environments. Regarding the building blocks of the cloud, KVM at 48% and VMware at 30% are the dominant hypervisors, and CentOS at 46% and Ubuntu at 36% are the most widely used linux distributions for OpenNebula clouds. The preferred choices for the storage back-ends are shared FS and SSH with a 52% and 36% ratio respectively. The most widely used Configuration Management Systems are Puppet and Ansible with a 37% and 14% respectively. Regarding networking, most of the deployments, a 49%, use the Standard Linux Bridge for network configuration, 38% use Open vSwitch, and 30% use 802.1Q. In comparison to the previous survey findings in 2012, the relevant changes are that CentOS has displaced Ubuntu as the most widely linux distribution to build OpenNebula clouds, and a growth in the number of production deployments from 42% to 62% and in the number of public clouds that has doubled from 21% to 40%. Although more than 2,000 users took part of the survey, we have only included in the analysis those respondents using OpenNebula 4.x (latest series) and who we deem reliable because they have provided identification details that allow us to verify the answers of the survey. This is important given that our main aim is to have accurate and useful information about OpenNebula deployments. Last, but not least, when asked about what you like most about OpenNebula, most users, a 76%, answered because of its simplicity, and 69% and 65% answered because of its flexibility and openness. These results are aligned with our our mission — to become the simplest cloud enabling platform — and our purpose — to bring simplicity to the private and hybrid enterprise cloud. OpenNebula exists to help companies build simple, cost-effective, reliable, open enterprise clouds on existing IT infrastructure. BIG THANKS to all the organizations that have contributed to the survey!

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!!

Thanks! I'm still having issues here unfortunately. I tried putting: FILES_DS=$FILE[IMAGE=\test.sh\] into my template context section, but I get: User 0 does not own an image with name: test.sh I'm not trying to include an image, I just want test.sh (a file in my file datastore) to get copied to anywhere on my vm's filesystem. (And eventually, I want test.sh to get run on vm creation, or failing that, every time the vm starts) Thanks!!

Re: [one-users] BOOTPROTO, DHCP_HOSTNAME, and vm IPs in Sunstone
It sounds like it's not really possible for a DHCP client to suggest an IP to the DHCP server. I think I would like to make a feature request: easy DHCP integration. Does my use case make sense? I can clarify further if needed. Thanks!! On Mon, Sep 8, 2014 at 12:35 PM, kerryhall . kerryh...@gmail.com wrote: 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!!

To add that parameters to network configuration you can do one of these things: * Create the network configuration in the base images manually and do not set network contextualization in OpenNebula so they are not overwritten. * Modify the context packages to add those parameters [1] For the third thing there is no way to do it. OpenNebula gets an IP from the network pool and assigns it to the NIC. There is no way to change it after it is selected and there is no external method of selecting the IP. What you can do is configure DHCP so it picks the same IP as OpenNebula had selected for the VM. The MAC addresses are generated from the MAC prefix and the IP, you can configure DHCP with those mac/ip pairs. MAC = PREFIX + IP in hex 02:00:0a:00:00:01 = 02:00 + 10.0.0.1 (in hex is 0a:00:00:01) [1] https://github.com/OpenNebula/addon-context-linux/blob/master/base_rpm/etc/one-context.d/00-network#L103-L114 On Sat, Sep 6, 2014 at 12:23 AM, kerryhall . kerryh...@gmail.com wrote: Hi folks, I have a small ONE cluster that I am currently setting up on 4.8. I have a ethernet network model, and I have added the following line to my template: SET_HOSTNAME=$NAME.mydomain.int So far so good, but I need to be able to do the following three things: 1. set BOOTPROTO=dhcp in /etc/sysconfig/network-scripts/ifcfg-eth0 on new vms 2. set DHCP_HOSTNAME=$NAME.mydomain.int on new vms 3. set the IP field in sunstone to vm's IP address provided by DHCP How do I accomplish these items? I was thinking run a bash script on vm startup for items 1 and 2, unless there is a builtin ONE way to do this, but what about item 3? Is there just a straight up DHCP networking model I can use to make this easier? Does anyone currently use ONE with DHCP? Thanks!!

Re: [one-users] Run bash script in vm on spin-up (Users Digest, Vol 79, Issue 20)
Please look http://docs.opennebula.org/4.8/user/references/template.html#context-section and http://docs.opennebula.org/4.8/user/virtual_machine_setup/cong.html FILES_DS and INIT_SCRIPTS. INIT_SCRIPTS is missing in context reference documentation. Regards, Rolandas Naujikas On 2014.09.08 23:09, kerryhall . wrote: Thanks! I'm still having issues here unfortunately.
