1) Message boards : Questions and problems : Cloning a BOINC preinstalled VM (Message 77548) Posted 24 Apr 2017 by FritzBox360 Post: Hi guys, after a nice skype call from Christian we decided to change some points. 1 --> We need unique hostnames. --> We created a small script wich adds the 5th and 6th octet of the MAC from the host. This was possible because our OpenSLX virtualisation gives us a marginal changed MAC from the host. So we have now all clients named with Ubuntu-XXxXX. 2 --> We created some initialization files for BOINC and the Project as mentioned here https://boinc.berkeley.edu/wiki/Initialization_files 3 --> We just clean installed BOINC but do not run it and we deleted the var/lib/boinc-client folder. After some testing we need to change the startup behavior because BOINC was started to fast and had the old hostname. Then we had a few network performance issues related to our network. But all in all - it should work now but just testet with 6 clients. But we will do some testing. An easier way for changing the ID and joining the project would be nice. Maybe a trigger for BOINC to change or check the ID on next startup - depends on what the ID is created. Just a new MAC does not work. With a new MAC and a new hostname it worked. We will try to do some more testing on that. Stay tuned. Greetings from Mannheim, Germany

Still the same problem that we have the same cpid and the clients are running the same tasks. Is there no "easy" way to create just new IDs e.g. at startup or with a specific command? We are running out of ideas here. Just trying to spend some cpu power but if all clients doing the same task this would be more than wasteful ... Any ideas here?

Deleting all the .xml files would be no problem. But how can i automaticaly add a project? We have about 120 possible clients and it would be to hard to go to each client. We have checked the boincmd but could not get it working. Each client ( VM ) has an individual MAC - so it should be possible to create new IDs but we could not figure a way for it. A skype call in german sounds nice :) - let me know if this is possible! Thanks a lot!

Our computer labs have a virtualisation infrastructure via VMware over OpenSLX. As a result of that we can create a single VM ( e.g. Linux / Ubuntu ) and install BOINC there. After that we upload this VM to our servers and every client will get these VM. We run into the problem, that all of our testing PCs had the same ID and were working at the same tasks. After a while the tasks failed. Inn our opinion it is sth. with the computer ID or another ID which should be unique for the clients/servers We found this --> https://boinc.berkeley.edu/wiki/Host_identification_and_merging And we are thinking about to configure the .xml files. We would like each client to connect to one account, assign a project and start working individual tasks. How is this possible? It would be fine if we had one preconfiggured VM that we just need to start on each client. If you have any questions about this - just feel free to ask! Thanks a lot
