The AMD Ryzen 9 7900X has virtualization support, but this is turned OFF by default, and report "virtualization not supported". Check in the BIOS that virtualization is enabled, then turn it ON. After rebooting that error message should disappear, however other messages may then appear, which may take a fair bit of work to clear them. Most common is trying to run the "BOINC supplied" form of virtual machine on a computer that has (or has had) the MS version of Linux installed, the two just aren't compatible with each other despite having very similar names....

I had the same problem. There is a work-around that appears to work:
Suspend the project before shutting down BOINC, then I can safely turn the computer off. This forces Virtual Machine to first stop processing the task then saves the Virtual Machine so it can restart at a later date or time.

(And I agree with you about wanting native tasks rather than VM -based tasks - life would be a little easier).

There is something strange going on with the initial estimated run time vs. the actual run time of some, if not all of these tasks:
On my PC:
Initial estimated run time = 61.5 minutes
During the first 60 minutes of running the elapsed time increments at about 1second per second of clock time, and continues at this rate - only a couple of seconds out after an hour.
However the remaining time only drops by about 15 seconds to 60.25 minutes.
At 61.5 elapsed minutes the remaining time jumps to 9 days 23 hours and 46 minutes.

This has the effect that my computer downloads a number of tasks that are, initially predicted to be finished by the deadline, but at the "1 hour" adjustment the majority will not even be started never mid finished by the deadline (10 days). This is potentially a rather unproductive waste of bandwidth, not to mention frustration for me. It will be interesting to see what the actual run time of these tasks is.

Well......
WSL uses "type 1" virtualization, but that is totally incompatible with the "type 2" virtualization used by the Oracle system deployed by LHC. As far as I can gather it is not possible to have both "type 1" and "type 2" virtualizations running on the same PC. It may be possible to do some form of dual boot allowing you to boot into either a "type 1" environment or a "type 2" environment, but I don't think either configuration would allow the other to run at the same time.

You have the same set of issues I had. Something (Microsoft??) decided to sneak in an update which launched Hyper-V and Hyper-V prevents Oracle VirtualBox from running. The not so simple solution is to unpick Hyper-V from your system (you need admin privileges), it can take a few re-boots to get rid of the last vestiges - search for "removing Hyper-V from a computer), allow an hour or more.

"Just turn OFF"....
40 minute later, several re-boots and I'm seeing the first LHC ATLAS simulations downloading, along with the expected(?) ATLAS v-box image (all 1.7GB of it).
OK, sit back and wait for the next fun instalment, but for now I think I've earned a drink.

Thanks, but....
When I check in the BIOS SVN (AMD's version of virtualisation) is enabled - I dissabled it, rebooted, then shutdown, enabled and restarted just to make sure. Now I am really confused, unless BOINC isn't re-reading the computer configuration correctly at restart/re-boot.


But, on checking the various services required fr VM to run were actually running they were turned off.

Now trying to see if setting them to automatic works and I have VB running.

For some weeks I've not been getting any LHC work.
The computer concerned has virtualisation enabled (in BIOS), RAM protection disabled (in BIOS), run native disabled (BOINC options & on website).
Today I noticed this set of lines:

I'm confused!
The computer has 16 cores (8 real, 8 hyper-threading or whatever AMD call it), and I allow BOINC to use half of them. Currently there are 4 CPDN tasks running, and given their known fragility at re-start I'm loathed to stop & restart BOINC to get a copy of the first 30 line of the log.
15) Message boards : Number crunching : Double counting? (Message 49300)
Posted 29 Jan 2024 by rob
Post:
The transfer from the projects is, as has been stated, by each project exporting an XML file. Once on the third-party (boincstats etc.), they may well then transfer the data to something like and SQL database on which they run a query, probably not on a continuous basis, but daily and follow the same basic process I outlined earlier.
I don't think there are many active projects with the same first "word", so this running the query with the project names in the reverse order may help eliminate this double counting, also the use of a tag for "this record has been counted in today" may also work (indeed may be better?).
How to "cure" on existing data - this is a thorny one, as it would require going back through the database and finding when this started then recreating the data from that point, which is no small task.

A quick look susggests this a boincstats issue rather than a BOINC issue. As boincstats.com is a third party you may well get some satisfaction by asking this question on their support forum.
My guess is that they are using a wild card search to generate the stats. Going down ones list of active projects and search for "lhc*" which finds both "lhc" and "lhc-dev" and assumes they are both the same project and adds the credit for both projects, it then does a search for "lhc-dev*", finds only that project and so presents that data on its own.

A couple more authorities that have a say in who can/can't work at CERN (including the LHC) are the Fench & Swiss immigration and visa people.
One consideration is that Russia is not a "full" member of CERN, only having "observer" or "partial" membership, so don't have the same sort of rights to be there as those from countries that are "full" members.

Sometimes teams will do a "dummy start" during boot, but as you say it shouldn't stop BOINC running tasks from projects, unless it has been added to the "don't run if one of the these apps is running" list, in which case BOINC will prevent any task from running.

Make sure you've got virtualisation enabled in the BIOS. Without it being enabled then most(all?) VM won't run properly.
As for Teams.exe - teams is MS's conferencing software, a bit like Zoom, but done by MS. This may be shipped and auto-installed with Windows 11. Check through the load at boot list and, unless you really need it, it can be safely removed.
