Meditation Guru critical error on Windows Host

Post by mycroft1 »

I have tried all the memory adjustment solutions and suggestions that I have found. I am attaching my log file. Any help correcting this would be appreciated. I am new to virtual machines so I'm not sure what to look for.
Thanks in advance!

Please edit your message, delete "part1.log" and "part2.log", ZIP the whole log and replace the two parts. It saves a couple of (virtual) trees. Thanks.

00:00:03.801878   VRamSize         <integer> = 0x0000000001000000 (16 777 216, 16 MB)
Your display RAM (vRAM) is too low. I'd take it to 64 MB or more.
00:00:03.810960 CPUM: Matched host CPU INTEL 0xf/0x6/0x2 Intel_NB_CedarMill with CPU DB entry
                'Intel Pentium 4 3.00GHz' (INTEL 0xf/0x4/0x3 Intel_NB_Prescott2M)
Not your usual CPU these days.
00:00:28.114245 !!         VCPU0: Guru Meditation 1155 (VINF_EM_TRIPLE_FAULT)
For Guru Meditation errors, you should head to the bugtracker and either search for an appropriate bug, or open a new bug report where you'll attach your logs and other vital information.

Based on the CPU that you have, I managed to find two bug reports that have the "Intel_NB_CedarMill" or else the "Intel Pentium D CPU 3.40GHz" that you have on your system, https://www.virtualbox.org/ticket/13034 and https://www.virtualbox.org/ticket/13160

Now, as luck would have it, I have an almost identical setup, same CPU with mine being clocked at 3.2 GHz. So, tomorrow, I'm going to try Ubuntu 16.04 and see what I get and compare notes. In the meantime, please take care of the one zipped log.

I have attached the log as a zip file. I tried adjusting the vRAM to 96 MB and still got the same error message. We looked at the tickets and one was empty, closed, and marked obsolete. The other one said that the error was fixed but for an older version of Ubuntu than I'm trying to install.
Thanks for your guidance so far and I look forward to hearing the results of your notes tomorrow.

Suggestion: Throw out the Pentium D processor. It's not good for anything, and never was.

Actually that's too harsh, the Pentium D is pretty good for keeping the place warm in winter.

Interesting. A true XP era HP desktop that's 64bit (one core) and supports VT-x? I didn't know those existed. I'm also surprised Win10-64 could be installed on it.

I see that you have the Hypervisor API enabled in the guest. ISTR getting crashes related to that - you can try disabling it as a test.

Also the early VT-x is a concern. Are you able to run 32bit guests?

I have a system like that, class of 2006. Working just fine (and not as a heater michaln ;) ) and it's actually my daughter's gaming machine for games released even in 2016 like Tomb Raider (2013), X-Plane (current) and Inside (2016). Not too many 10-years old computers can do that:
  • Came with XP initially and it now successfully triple boots Win7-32/64 and Win10-64.
  • Pentium D @ 3.2 GHz, 2 physical / 2 logical cores.
  • VT-x available and enabled.
  • NX was available, but I only enabled it due to this thread because it never was a problem so far.
  • Use it also as a backup for my VirtualBox VMs. Runs every VM (with lower memory maybe because it can only take up to 4GB total), except my OSX guests.

@mycroft1
Thank you for zipping the log. I have good new and bad news. The good news first: I got the same setup to work. The bad news? Only under Win7-32. Let me explain...

My setup is almost identical to yours [1]. But, I triple boot between Win7-32, Win7-64 and Win10-64. The VM is shared between OSes, i.e. same VBOX, same VDI, same preferences. On Win7-32 it works. On Win7-64 and Win10-64 it fails with a guru meditation error, same exactly like yours. I can find only the minuscule of differences between the runs and I'll list them briefly:

00:00:05.044710 PGM: Host paging mode: AMD64+PGE+NX   Win7-64/Win10-64

So, it seems to fail with 64-bit Windows (be it Win7 or Win10). I'm attaching the logs and afterwards I'll start looking for an open bug report. If I can't find something that fits, I'll open a new ticket and I'll post an update to the thread.

PS. Changing paravirtualization between "KVM" and "None" has no effect whatsoever. Same with PAE/NX.

If you want to get updates about this, just post a comment on the ticket. You're auto-subscribed to receive e-mail updates from the developers (hopefully) about this...

PS. I just happened to have an extra computer with the same setup. Thank your luck, not me ;)

As luck would have it, we were just in the process of reviving an old system with a Pentium D processor (Pentium D 950, 3.4 GHz). It runs Linux but shows the same problem with the guest OS triggering a triple fault. We'll look into it, and will use the ticket for further communication.

The winters must be harsh where you live...
Sorry, couldn't resist :D

Thanks for looking into this. Ticket #16375 will be the active "forum" for this now. I will simply update this thread once a resolution has been achieved.

Well, we risked the cooling budget of our test lab but we did it just for you guys!

But seriously, I have a 6 year old CPU which at the same TDP has at least 10x the computing performance of the Pentium D. It's not even funny how bad the NetBurst architecture was.

You don't have to tell me. A year and a half ago summer was relatively hot over here. That puppy blew 4 power supplies. In a month! Solution? Open the cover and stick a big house fan right on it's motherboard. Now, besides the 540 W power supply I also have the fan to worry about blowing a fuse. That's why it has since become my "winter" system ;)
