no WU;s for virtualmachie(vbox)

i set up a VM for CEP2, but i get "No tasks are available for The Clean ...". It recives WU;s for other projects, and the host machine recived WU;s for CEP2.

So are there no tasks available and the ones recived by the host was a fluke, or CEP2 does not like virtual box?

Re: no WU;s for virtualmachie(vbox)

Could be several reasons:

- CEP2 queue temporary empty
- VM-disk too small
- setting of <no_alt_platform>1</no_alt_platform> in your cc_config.xml

etc.

Re: no WU;s for virtualmachie(vbox)

To add some points to check:
- sufficient amount of ram
- 64 bit Linux works for me only with modified platform string in cc_config.xml

Re: no WU;s for virtualmachie(vbox)

the VM (VirtualBox) has 80GB of space, 3GB RAM, so that should be enough i guess. The host is linux 64, the VM also linux 64(ubuntu variant).
Could you give me a hint of what i must modify in cc_config.xml !

Re: no WU;s for virtualmachie(vbox)

The issue is, you got all the other sciences because they are available in 64 bit. Not CEP2, only in 32bit, so you have to use the tag given by Crystal Pellet, think with a value of 0:

<no_alt_platform>0|1</no_alt_platform>
If enabled, the client will run applications only for its primary platform. For example, a Win64 machine will run only Win64 apps, and not Win32.

and

<alt_platform>i686-pc-linux-gnu</alt_platform>

This one will though stop 64 bit apps to come FAIU.

Re: no WU;s for virtualmachie(vbox)

Eventually you need to install some packages to run the 32-bit application for cep2 but I would give the cc_config.xml a try first.
This page might give you a good read for the needed packages: click

In the cc_config.xml make the changes described below.


<cc_config>
   ...
   <options>
     <alt_platform>i686-pc-linux-gnu</alt_platform>
     <no_alt_platform>0</no_alt_platform> 
     ...
   </options>
 </cc_config>

When the changes are done boinc needs a restart. A boinccmd --read_cc_config is not sufficient.

Hope this helps

Re: no WU;s for virtualmachie(vbox)

Yey it works ! Thank u all for the great help !

Changed cc_config as Eric said, installed the extra libs - just in case, and a reboot later it worked.

Will make a 32bit VM when i'll get the time (or maybe there is no pennalty for running on 64?)

Re: no WU;s for virtualmachie(vbox)

I am a noob when it comes in Linux. I recently got a machine, installed Ubuntu on it and all the WCG projects to run on it but I can't get any CEP2. 8 gigs of ram, 4 threads, plenty of HDD.

I tried to edit the cc_config.xml as mentioned above but can't save the edits as the permissions are set to:
Owner: boinc core client access: read and write
group: boinc access: read only
others access: read only
"you are not the owner, so you cannot change these permissions"
The options are grayed out so I can't change anything.

As a work around I tried to copy-paste the entire folder then delete the old folder, modify the file and replace the folder with the one I just made but the gui_rpc_auth.cfg won't copy.

Any advice would be most appreciated.

Re: no WU;s for virtualmachie(vbox)

Yeah, Linux is a 'little' [euphemism] more secure ;). There's the data dir /var/lib/boinc-client, which is protected. The cc_config.xml is, on my Ubuntu, -symlinked- to the source which is in /etc/boinc-client folder. That you can edit with for instance

sudo nano cc_config.xml

This folder holds about 5 user editable files.

Re: no WU;s for virtualmachie(vbox)

A bit of trial and error and now I am downloading CEP2 files. Thanks much :)
