Message 58322 - Posted: 30 Nov 2014, 18:25:18 UTC
Last modified: 30 Nov 2014, 18:26:26 UTC

I had an BOINC update to install and it advised that I install Vm too. So I thought ok, it will be of help later on. I installed it and got a message telling me that VM failed. But the desktop icon was on screen. So I continued installing Boinc then went back to look at VM and a window opened; so I presumed failure message was in error. Then I looked at something in VM and the only options were 32 bit although my pc is brand new 64 bit and VM is recommended for 64 bit only???? Also I am win 8.1.

I uninstalled it and await an answer.

I have been processing SETI for years but no idea what VM does, I looked at help or something and it said I can 'install' a virtual OS in it?? Huh?

I had an BOINC update to install and it advised that I install Vm too.

There's a link at the download site that shows you if you need VirtualBox or not and what it is. The line of text says at this time We recommend that you also install VirtualBox, so your computer can work on science projects that require it. Learn more about VirtualBox.

Going the link, you'll come to the Wiki where it says:
Virtualization is a software technique that allows a computer to run a different operating system within a self-contained "virtual machine" (VM). For example, this allows a Windows computer to run Linux, with no need to install Linux separately on the hard drive, or to reboot when switching between the OSes.

and
The use of virtualization in BOINC provides several advantages:
• It makes it easier for scientists to develop applications for BOINC, since they no longer have to build and maintain versions of their programs for Windows and Mac.
• It provides increased security for volunteers. Virtual machines provide a very strong security barrier; a program running in a virtual machine has no access to the files on the "host" operating system.
• VM apps are automatically "restartable". The contents of the VM are written to disk every few minutes, and if your computer is turned off for a while, the application can restart close to where it left off.


and
The following projects currently have VM apps:

• Beauty@LHC
• Climate@Home
• RNA World
• Virtual LHC@Home
• Atlas@Home

Even if you're not participating in any of these projects, we encourage you to install VirtualBox; that will allow more projects to use virtualization in the future.


Meaning that if you only run Seti@Home, you won't need to install VirtualBox at this time. When a project is in the process of releasing an application via VM, they will tell their userbase about this through all possible channels, including the forums, the Notices tab and possibly even emails.

Then I looked at something in VM and the only options were 32 bit although my pc is brand new 64 bit and VM is recommended for 64 bit only????

VirtualBox is a 32bit program. It can run 64bit operating systems within its virtual machine, but doesn't require itself to be 64bit to do so. So that's of no worry.

Unless you have added a project that uses the virtual machine, you will have no virtual machine, so no guest operating system in VirtualBox. VirtualBox will then be just another program on you computer, waiting for things to happen. Only by adding one of the aforementioned projects will that project upload a virtual machine to your VirtualBox. This new virtual operating system won't take over your Windows, it won't run in Windows, it will run in VirtualBox.

Having an error when installing will usually mean that there was an error during installation, due to which something didn't install. Like the virtual network. So don't so easily brush off errors during installation of programs.

I was about to install it, from Oracle, when it flashed a warning that it was going to 'reset' my network and temporarily disconnect me.

what does it mean 'reset my network' ?

I have 152mb+ broadband via virgin media (uk) and I dont fancy anything being tweaked as it is set just how I need it, including a static IP for my wireless printer.

When you install VirtualBox, its installer will install a virtual network card and virtual network connection with its own IP address and network name.

To finalize installing this 'new hardware and drivers', Windows has to reset all of its network connections. Afterwards Windows will be able to recognize the new network card, the drivers for it, the name, the IP address etc. etc.

This network is used specifically by VirtualBox only to make contact with other VirtualBox VMs on your computer, or on your network, it will not in any way overtake your normal internet or network connection(s).

A lot more information about the virtual network of VirtualBox can be found at https://www.virtualbox.org/manual/ch06.html.

Nothing about your internet connection, external IP address or printer will change.

GPUGrid also as a VM app that it sometimes sends out. Perhaps someone will update the wiki. The error that OP mentioned during installation has happened to me on many installs and seems to be a false alarm as the VirtualBox seems to work just fine afterwards. I can certainly see where there might be some confusion.

The list in the wiki is primarily for projects that only use VBox, not just sometimes. When GPUGrid has a full-time application, I may consider it.

Also, since they call themselves GPUGrid, one would expect that the calculations happen through the GPU, something that present day VirtualBox hypervisors cannot do yet. So that would confuse people even further.

thanks ageless, so I will go ahead and install the oracle windows vm and see how it works with a vm orientated project. (I think ;) )

I agree. However, on top of the VM work they also have a test app for multi threaded CPU work and they also periodically run work on ARM. I have brought up the name issue via PM before but it never got a response. Not sure why since they already went from PS3Grid to GPUGrid...

I have been running BIONIC for a couple of years with milkyway@home and cosmology@home running fine.
I recently started atlas@home with VM installed. I've noticed the program running slower and slower as it gets nearer completion with the last few 'seconds' taking hours to complete. The computation has been running now for 100 hours and it says its 100% completed which it has said for the last 25hrs. It just keeps running and will not send the completed program. Deadline date in 27 Dec 2014.
It says it using 3.42GB HD mem with 12.26GB available for BIONIC.

If restarting BOINC does not work, occasionally the VM will hang, a restart will clear it, then I would suggest asking on the Atlas forums.

For this problem, please read http://boinc.berkeley.edu/dev/forum_thread.php?id=8600&postid=50407 as we will need to see the beginning lines of the event log to understand what BOINC is thinking.

By unlimited, do you mean on the disk and memory tab of computing preferences you have set:
Use at most 0 GB of space
Leave at least 0 GB of space
Use at most 100% of space?

In any case the event log will tell us what is set, no matter what you may think is set.

This is what the computer reports for your disk drive to BOINC
27/12/2014 09:10:34 | | Disk: 924.87 GB total, 804.87 GB free

And this is what BOINC thinks it has available
27/12/2014 09:10:34 | | max disk usage: 808.26GB

How BOINC thinks it can use more disk than is free escapes me! Someone else is going to have to chime in on how BOINC can think it can use more disk than is free! It should have reported 724.38GB as max usage based on your 90% number. It is possible that BOINC is corrupted and a reinstall is needed or perhaps there is a logic error in BOINC that has not been spotted before, why someone else needs to chime in.

I see from "09:10:34" to "12:44:32" there are no entries, especially no entry "ATLAS@home | Starting task xxxxxxxxxxx" or it starting any other task nor any message indicating why it did not start any task!
I also see no entry about any shortage of disk space.
I'm suspecting that you didn't send part of the log file. (It is very hard to debug if you can't see where it tried to do something and the reason why it didn't.) If that is not the case and there are no missing entries from "09:10:34" to "12:44:32", then my advice is to uninstall BOINC, download a new copy and install.

I know ATLAS units take a bit of disk space, I've got 5 on my machine right not taking about 5.5GB of space, but you have gobs of hard drive available in comparison, enough for hundreds of work units.

BTW that work unit http://atlasathome.cern.ch/workunit.php?wuid=365797 has been crunched by someone else and it validated.

It should have reported 724.38GB as max usage based on your 90% number.

Actually, the 90% is calculated over the total disk space or the amount that the partition is that the data directory lives on, not over the free amount. So if the total disk space is that 924.87 GB, then the value there should be ( 924.87 / 100 ) * 90 = 832.38 GB.

Also, something that will show in future clients, but was always enforced: BOINC will use the most restrictive of these three settings, so either the Use of total, Leave at most or Use at most. It won't use all three.

Having said that, I cannot explain why the Max disk usage is of a value none of us can calculate. Have forwarded that one to David.

OK, to get all the numbers, you'll have to use the values from the Disk tab.

The below example is from my BOINC.
Use at most 0 GB.
Leave at least 0.1 GB free.
Use at most 90% of total.

27/12/2014 17:08:01 | | Disk: 244.14 GB total, 112.01 GB free
27/12/2014 18:47:42 | | max disk usage: 113.60GB

According to Disk, my BOINC is actually using 1.72GB, it can use another 116.11GB and other programs use 126.21GB.

So...
244.14 total - 112.01 free = 132.13
132.13 - 1.72 BOINC = 130.41 Max_delta
244.14 total - 130.41 Max_delta = 113.73 - Leave at least 0.1 free = 113.63

Close enough.

The max usage is the minimum of the 3 preferences, in this case the Leave at least 0.1GB free.

Wow. It looks like BOINC is not starting the task and also not logging why it won't or can't start the task. Since the error message about disk space isn't in the event log, where did you see it?

The error message was in BOINC Manager's Notices. I'll leave it one more day and then abort, if not solved.
