Go to your BOINC folder and edit the file client_state.xml
Remove the line which contains <p_vm_extensions_disabled>

Yes, that worked.
Thank you for your assistance.

I seem to be unable to get any camb_boinc2docker work units for my computer '278205'.
All I get is:
04/01/2016 2:52:10 PM | Cosmology@Home | Sending scheduler request: To fetch work.

04/01/2016 2:52:12 PM | Cosmology@Home | No tasks are available for camb_boinc2docker

even though the server status says there is plenty of work available.
I have 64-bit Boinc version 7.6.22 and VirtualBox 5.0.12 with VT-x enabled, and I know this setup works because I have successfully completed 2 VirtualLHC@home work units.
I reset the project, which didn't help; neither did detaching then re-attaching the project work either.
I can't think what else I did wrong.

My Linux computer has downloaded vboxwrapper_26175_x86_64-pc-linux-gnu and vm_isocontext_v0.4.iso, and now all the work units that I have done since have run properly and validated correctly.

I am using Boinc version 7.2.42 with VirtualBox version 5.0.6

Update: I've got some work on my Linux machine, and I've finished 2 work units, but it's hard going!
The work units stop after about 20 minutes with no reason given in the Event Log, but in the work unit Properties it notes:
State Waiting to run (Scheduler wait: VM job unmanageable, restarting later.)

When I reboot the computer the work unit picks up where it left off, except that the Elapsed time drops down to the last checkpoint time.

Both work units stopped again before they finished, needing another reboot.

I'll finish my current batch of work, but I'm not doing any more Linux work until I've figured out what I did wrong.

Having got this project working properly on my (other) 64-bit Windows computer, I am keen to test it out on my 64-bit Linux machine.
It runs Ubuntu 14.04.3 and has Boinc version 7.2.42 installed.
I have downloaded virtualbox-5.0_5.0.2-102096~Ubuntu~trusty_amd64.deb, but I haven't installed it yet.
Will this combination work OK on this project, and is there anything special that I need to do to configure the VirtualBox installation, or will the work units just work fine without doing anything else?

My search on the Intel website:

http://ark.intel.com/products/27480/Intel-Pentium-4-Processor-640-supporting-HT-Technology-2M-Cache-3_20-GHz-800-MHz-FSB

revealed: Intel® Virtualization Technology (VT-x) ‡ No

So I guess I can't use this computer for Beta testing.

I think your CPU supports virtualization, you probably just need to enable it in the motherboard BIOS.

If you are referring to VT-x then according to CPU-Z my old Pentium 4 processor doesn't support it.

The best I've been able to find out why my work units aren't running properly is this entry in the Virtualbox log:

00:00:00.355858 WARNING! 64-bit guest type selected but the host CPU does NOT support HW virtualization.

My CPU is an Intel Pentium 4 640 @ 3.2GHz. It is 64-bit.

I guess I'll have to give up on testing out this project. Pity.

I was keen to try this out for you so I installed the latest Boinc version 7.6.9, which comes with VirtualBox version 4.3.12
I appear to have downloaded all the needed files, but my 2 work units won't start; there is the message in the Event Log:

04/09/2015 11:53:02 | cosmohome | task postponed 86400.000000 sec: Please upgrade BOINC to the latest version.

EDIT: Ignore this message. I stopped, then restarted my Boinc client, and now the work units appear to be running correctly.

MORE EDIT: My work units are running in the Boinc Manager, and also in the VirtualBox Manager, but there is no CPU activity, and the work units are still sitting at 0.1% after 30 minutes running.

Unfortunately this project has quite a few "ghost" work units, where the work file does not exist.
If you get one all you can do is abort it, and try to get another work unit.

I eventually got Cosmology working under Linux by copying the camb_2.16 application across from another computer that was already attached.
I never did succeed in downloading the needed file on my machine, despite trying many times!

I am completely unable to download the camb_2.16 application under linux.
The download stops partway through, and there doesn't seem to be any way to force it to complete downloading.
All I can do is detach and reattach, or reset the project, neither of which make the application download completely next time, and all it ends up doing is wasting my internet allowance and ruining work units.

Check if a PowerSave program or something similar is enabled. This throttles down the CPUs very much.


OK, in Services I have disabled "CPU Frequency manager", and my benchmarks have gone up by 30%, so now they are about two thirds of the Windows benchmarks.

I suppose I can be satisfied with that.

I hope that by disabling the CPU Frequency manager it won't cause any problems for the CPU.

Can anyone tell me why my benchmarks under Linux are only half as much as those under Windows?

Is it a hardware issue, or an operating system issue, or a BOINC issue?

The Windows side is using 6.6.36, while the Ubuntu side is using 6.6.40.

The application 2.16 only seems to checkpoint about every 2 hours.
Can this interval be shortened?
For example, I understand that Einstein checkpoints every 2 minutes.

My computer is dual boot (Windows XP Home and Ubuntu 9.04), so I have been trying to find out which version crunches Cosmology work units quickest, but due to differences in run times I have been unable to form a conclusion.
Is there any real speed difference between the Windows and Linux applications?

I haven\'t been able to download any work for a couple of days.
My machine requests 30,000 seconds of work, which succeeds, but gets 0 tasks.
The project is set to \'allow new tasks\'.
