Upgrading the Tango virtual machine

Hi Philippe, I just downloaded the VM from home and it took < 1 hour. Average speed was 1.7 MB/s and I am not on RENATER. I think that either you were unlucky and the network was overloaded or there is a problem with bandwidth between your machine and the ESRF. Good to hear that you got it and have the list of packages now. Any feedback on what is missing or needs updating? Your feedback will be appreciated. I plan to make improvements to the current release candidate in the next weeks. Andy |

AndyThe FTP seems to be hosted in ESRF local network, so you probably downloaded it from the same local network. Could you confirm you got this bandwidth from the same local network? If so, perhaps someone could check the speed from outside? AndyActually, I am doing a virtual machine on openstack, based on a debian. It seems we have all necessary soft, but I will netoify you if we miss anything for sure.

Philippe, I got the download speed I mentioned above from outside the ESRF using ADSL from a private home. I am interested in your experience with OpenStack. How are you deploying the Tango VM? As it is or do you have to modify it? Andy |

AndySo I suppose it depends on the moment of the day. AndyMy goal is to create a virtual server to host developping tools. OpenStack is a cloud solution hosted in our labs which allow to host and run VM into a more resilient way (and to add CPU or memory iof needed). I create a VM based on a debian image, preexisting on our openstack network, and I log in this VM to install TANGO. For this step, I used a script we create to configure our servers, dependending on the tools we need. Then, I have to install the packages I need. This is why I needed the list of packages installed into the tangobox. By the way, do you know if there is any special configuration for these packages (apart TANGO basic configuration with TANGOHOST) ? There is another way to create an openstack image, which consists into converting an existing VM to an openstack image, but I need access to OpenStack host network to use it. I wait for this access to try this way.

PhilippeThe image of tangobox is 18Gb (100Gb uncompressed). The image I got by converting it into openstack image is 17Gb (and 100Gb uncompressed also). This is far too big for the policy of the cloud we use (the philosophy is to have small images for system and to store date on persistent disks). Besides this point, I noticed that uncompressed image of tangobox is 107Gb (you can see it into VM details, into "storage", next to tango92-vm.vdi). However, into the VM, I got these informations which does not seem consistent :
It seems strange that total VM size is 107Gb but the space detected inside the VM is only half this size (53,7Gb). Perhaps some lost space could be saved here… Whatever, because of this size issue, I have to create an OpenStack VM from scratch. To do this, I need not only the list of packages I already found (see above) but also the list of configuration steps to follow to create the VM. I imagine the creation of the tangobox VM used a script (including the ubuntu used distribution, possible /etc/apt/sources.list changes, config steps with debconf-set-selections, manual steps for soft like eclipse…). Is this script available somewhere ? Actually, I tried to install an OpenStack tangobox VM based on an ubuntu 14.04.4 LTS (ubuntu-14.04.4-desktop-amd64.iso), by importing packages sources from tangobox92-RC1, replacing sources.list by the one from tangobox, updating database, and installing the packages list I got from the tangobox92-RC1. However, somes additional configuration steps are needed to install an openstack tangobox the same way as the virtualbox was installed. The installation cannot succeed without theses steps. Does anyone knows who create the tangobox? And is there any script (or descriptions of the installation/configuration steps) to create this one? Thank you
