Yes, "Show Graphics" now goes to the actual running job.

On the Linux host, I'm getting yellow-triangle ghost images left behind in VBox Media Manager when a task finishes, which have to be manually deleted. I freely admit to being not much good with Linux so it could be something I haven't set up correctly here.
No ghosts on Windows hosts.

Windows host also completed its task, reported, credited and, with all other cores busy, booted up and started a new job.

I allowed the Linux machine and 1 Windows host to get 1 of the latest 5.07s each so as not to have to Abort any on finding that it didn't work. From CP's comments on them possibly not being too happy if they weren't getting all the attention on start-up, I suspended most other work on those hosts and both are currently running Jobs. WooHoo
I resumed all other LHC sixtracktest tasks but I have limited these at single-core, single Job so we'll see if they start up ok normally when these finish.
Linux box finished 1 job, Task reported and credited, new task booted fine and new Job started.

Strangely, "Show graphics" on both hosts lands on the SAME partially complete Vincia job, that I'm not running, but clicking through to the logs gets to the logs of the actual running jobs. Even the new Tasks again lands there.

Single-core Base Memory has gone up from 730MB to 1500MB which means that where my 2-core Linux host with 4GB of RAM used to be able to run 2 x Theory (VBox or Native), it can now only run 1, with another "waiting for memory". 1 just started on a Windows host: 2-core (accidentally, I usually prefer singles) memory 2250MB

From the BoincVM thread "it should be possible to manage the BOINC client in the Guest via a Web browser."
"Show Graphics" button gets to an Apache landing page. Is this where that control will be?

Same output as CP.
Comparing the stderr of Laurence's successful task: mine gets to the line corresponding to
2019-09-23 16:00:54 (11016): Guest Log: 00:00:00.008616 main 5.2.6 r120293 started. Verbose level = 0
but no further.
The next line is the shutdown so I'll leave it for now and see what happens in an hour or so. These might just be "Blanks", not intended to do any actual work as presumably there would be details of a Job between those 2 lines.

No tasks for either VM overnight so seemed as good a time as any to end them both after 42 and 40 days. Both had got to 99.9xx% but estimated time remaining had slowed to about a minute reduction per day.
They have both left a powered-off VM in VBox and a yellow triangle image in Media Manager. Might see later if one of them will start without any Boinc involvement.

Task didn't finish after running out of work; it has just been doing the screenful of
==== Tasks ==== lines since reporting its last job this morning. I have changed it back to accepting 2 jobs but it hasn't done that request yet. I don't know what the back-off would be or how to force a manual update so it'll be idle until it makes that request.

Didn't take long, <1/2hr, before I even had a chance to post this update. Back to 1 x Executing and 1 x waiting. Think I'll limit both of them to 2 jobs so as not to waste any when they do eventually expire or are superseded.

Take-aways so far (for whenever the next version or more of these become available):

I set my hosts to School where they would only accept BoincVM to get these.
I didn't have to do ANY fiddly setting up that would normally be required to get Native to work. (Theses are running on Windows hosts)

The localhost VM will start with the preferences of your Default location (regardless of the Host location) so Theory MUST be ticked there or you only get ==== Tasks === on the console. I initially had 4 jobs, 1 CPU selected so the VM started with 1 CPU and got 4 jobs (1 running, 3 waiting). I don't know if 2 or more CPUs would work (yet) and jobs can be reduced to 1 or 2.
Q. Would they (could they?) run CMS or ATLAS if they are ticked or are they limited to Theory_Native for now?

Time Remaining estimate is currently irrelevant. These started at 4 days but are still going strong after 23 days. Remaining Time within the VM and therefore Fraction Done aren't accurate either. Elapsed time looks fine.

If suspended and allowed to save before exiting Boinc, they will recover from any number of Host reboots. I try to avoid harsh, instant shutdowns but suspect they would even survive such and at worst, might restart the Executing job.

The localhosts collect their own credits for each job returned so even if the Boinc task has an error (Timed-out, Aborted etc), therefore no credit, the localhost credit is unaffected.
Q. Will subsequent VMs use the same localhost ID or will a brand new one be created each time?

Hope these observations are useful.
it should be possible to manage the BOINC client in the Guest via a Web browser.
Might you glean some useful pointers from the Christmas Challenge stuff from a few years ago, if any of that is stored somewhere? I THINK it only worked as Firefox/Chrome plugins. Just found cernvm-webapi-1.2.8 and cvmwebapi-2.0.13, that I obviously never got round to deleting.

Woke up early. Tried to set zero request; not available. Tried to deselect all apps which defaults to ACCEPT all apps so I have unchecked all except BoincVM, of which there are none available so should mean it doesn't get anything, unless Laurence releases a new version today which might result in interesting nested VMs.
Should find out what happens before 9:00UTC.
Won't be there to observe or intervene as I'm at work, now.

Tonight, I have changed the "location" of one of the localhosts and allowed it to only request 2 Theory tasks, from the previous default of 4, which it accepted so I now have 1 Executing and 1 Uninitialized (waiting to run). Overnight, I have reduced it further to a single Task. Tomorrow evening I'll knock that down to zero and see whether the VM ends on completion of the job/task or reverts to the ==== Tasks === lines as at start-up.

Weekly update.
99.2% 20days 18hrs, 4hrs remaining and
98.4% 19days 6hrs, 7hrs remaining … although for both, the remaining time has slowed to around 30 real seconds per task second.
Both still healthily returning McPlots

As the rate of remaining time slows exponentially, there seems little likelihood of a natural finish.
The first thing needed is for the VM to shutdown if it does not receive any tasks,
With 2 jobs always cached, ready to run, there would need to be a fairly long job-supply hiatus for this to occur. Would robbing it of network access achieve this, at the cost of not returning the last 3 or 4 jobs? Will there need to be a manual kill? Aborting the already overdue Boinc Task? … Not that I WANT to kill them. Just wondering what to do when v.0.04 comes along.

If anyone wants to try, you can log into the VM as root using your authenticator as the password. You can then attach to Cosmology@home and try it out.
What would the "Authenticator" be? I've tried my account ID number and even copied the whole "weak account key" but neither lets me in to test this. (I'm a GUI person rather than command-line so maybe better that I can't get in ;¬)

Very impressed by the robustness of these. Both came through the Antivirus reboots unphased so I did the Windows 1903 Features update as well and both survived. I had difficulty with one host that had a series of partial installs, crashes, roll-backs until I eventually tracked down and updated a driver for a card reader that I have never used, with no help from Windows troubleshooter. On that one the VM did Power Off, which would normally signal loss of the running "job" but even that recovered without losing the 2 waiting jobs. The EXECUTING job may have started over, but impressive survival nonetheless.
14 and 13 days in. Still going strong.

13 and 12 days and local hosts both still running fine, returning jobs. BoincVM tasks timed-out on the website long ago with no effect. Both 90+% but remaining time has slowed to 1 second per 7 or 8 real-time seconds. From original 4 days estimate, it's still claiming 18hrs left so might run forever without manual intervention. I haven't interfered with them at all but my Antivirus has been requesting a restart since the weekend. I'll let the younger one do that this evening and we'll see if it checkpoints and recovers.

Both Boinc tasks, 2791895 and 2791928 which created localhosts 3861 and 3869 respectively, are still happily returning tasks and McPlots after 6 and 5+1/2 days.
Both look likely to overrun their deadlines (Friday evening and Saturday morning) but I won't be able to see what happens then as I'm away to Dunaverty Golf Club tomorrow to play in their Holiday Open on Saturday. (Short but testing links course with small but perfectly formed greens that are well worth the 3hr drive.) Also on Friday sometime I'm going to attempt a Summits-On-The-Air activation on 2m FM from Beinn na Lice (Mull of Kintyre) I wonder what the overlap is of Boincers and Radio Amateurs? Might do a Café enquiry post.
If that deadline triggers the ending of the Boinc tasks, I'll miss it but if they run to Remaining Time Estimate, which is still ticking at half regular time, then they might not finish until Sunday, by which time I'll be back

Mine have that too. The Tasks already run WITHIN a VM so don't need a further layer of virtualisation.

Break ==
Other post
I've not looked in logs, only through Console. I would expect job details in those logs rather than just time stamps so I suspect it's not getting jobs.

Break ===
Looks like mine have up to 4 tasks within the VM:
1 ready to report
1 Executing
1 or 2 Downloaded, Uninitialized ie. waiting to run.

Is the Boinc inside the VM clever enough to not get spare jobs as the end of the Host Boinc Task approachs?

Hi Samson
That screenshot shows that the VM has been set up correctly but for some reason has not been able to GET any Tasks, even after repeated attempts. Mine got Tasks after 3 or 4 attempts. Successful connection would produce the output shown in my earlier post.
Still some work for Laurence to do on Monday morning.

Maeax
I got a couple of
====Tasks====
lines when the guest started up but then the Tasks started and seem to be working fine since, returning and requesting new tasks. Perhaps your VM isn't able to call out? Perhaps, being Linux on Linux, it needs something different from Linux on Windows. Perhaps I've just been lucky that it appears to have worked for me first time.
I wouldn't expect any reply or update from Laurence until Monday. Maybe it would be better to release new apps early in the week rather than on a Friday.

Hi Maeax,
My understanding of Laurence's original post is that the Boinc VM App creates the localhost SL Linux virtually (just as it has created this host on your own machine, although you appear not to have gotten any jobs there for some reason) in order to allow running of Native (Linux) tasks, which I can't normally run on my Windows hosts.

I believe the Boinc instance within the VM does all the work while the Boinc outside, on the physical host does nothing other than create the VM and perhaps destroy it on completion.
I'm open to correction or clarification, but that's my interpretation of what's going on.

My 2 localhost Linux hosts on different Windows machines have successfully completed 8 and 6 tasks respectively. There might now be more confusion as these Virtual hosts are running Tasks which would have been called Jobs had they been run within a Boinc Task 8\

Morning update
My shiny new localhost has successfully completed 5 jobs overnight, all credited and showing in McPlots 8¬) and 3 tasks in progress.
Console window shows Task 1) complete and Tasks 2) and 3) running
all still within the original Boinc Task on the real host. Still not sure why 2 tasks appear to be active when I specified only 1 core and indeed there is only 1 core in the VBox panel.
Still 4 days remaining after 13hrs runtime.
Seems to be running well enough to allow my other host to try one.
Also looks good straight away, or at least it looks the same. Maybe too early to judge outright success until we see what happens when the Boinc portion of the Task ends.

Win 10
Boinc 7.14.2
VBox 6.0.10

version 0.03
Started off with 4 =====Tasks==== lines a per Maeax but after a few minutes it looked like this screengrab that I took 20mins in



Numbers in top and bottom sections are similar but I have set to use only 1 CPU so I'm not sure if it is trying to run 2 jobs on that 1 core?
It's estimating 4days+ to completion but that estimate is only ticking down 1 second for every 2 seconds real time.

Looking at my Tasks, I see one Task running on my host and another on a new localhost, presumably within the VM created by Boinc on the real host. Will that result in a new computer id being generated each time Boinc starts a new task and therefore a new VM or will the localhost id pass to the new VM?

I thought I'd followed your instructions but either I didn't create the file correctly or I didn't put it in the right place as I still got the same error.
Can't get any more of those tasks to experiment on so hopefully that means the adjustments tested have fixed the credentials problem and my 6 days of uncredited CPU time were useful.
In fact, I can't get ANY Theory tasks here just now.
