I am having trouble booting TinyCore Linux (8.0) on VirtualBox 5.1.28; I get a fatal error when it starts the kerrnel (VERR_PATM_IPE_TRAP_IN_PATCH_CODE), log is attached.

A brief set of notes on the VM configuration, where the TinyCore ISO image was retrieved here:

I searched the forum and found this, although it was never answerd:

Any help is appreciated! Thanks!

Please change the template to "Linux 2.6/3.x/4.x (32-bit)".

I get a warning in the settings when I set 4 MB of VRAM on my system.

Then you have a series of similar messages, just before the Guru meditation:

I have the suspicion that it has to do with a couple of factors, but mainly it's the "Enable VT-x/AMD-V" that's causing your Guru meditation.

The problem arose because you chose the wrong template, "Linux Other 32-bit" and the wrong defaults were applied. I'm going to copy/paste your settings as you posted them, but with the correct values for a "Linux 2.6/3.x/4.x (32-bit)" template. Please change the settings in your VM to match those below. The bold ones need to change:

• System
  -> Motherboard
  ---> Base Memory: 512 MB
  ---> Boot Order: Optical
  ---> Chipset: PIIX3
  ---> Pointing Device: USB Tablet   (That was acting weird. You might want to leave it to PS/2 mouse.)
  ---> Extended Features: Hardware Clock in UTC Time
  -> Processor
  ---> Processor(s): 1
  ---> Execution Cap: 100%
  ---> Extended Features: None
  -> Acceleration
  ---> Paravirtualization Interface: Default
  ---> Enable VT-d/AMD-V: Checked
  ---> Enable Nested Paging: Checked
  Display
  -> Screen
  ---> Video Memory:  16 MB
  ---> Monitor Count: 1
  ---> Scale Factor: 100%
  ---> Acceleration: None checked
  -> Remote Display: None checked
  -> Video Capture: None checked

socratis, thanks for the reply!

I indeed got it working using the following two changes you suggested:
Template: "Linux 2.6/3.x/4.x (32-bit)"
Enable VT-d/AMD-V: Checked

The rest I kept as I had them because I am emulating an old environment.

A couple questions, if you don't mind...
What is the generic Linux template for?
Any idea why Guru meditation would occur without virtualization support in the hardware? I figured without it, the emulation would occur without acceleration but still work functionally the same way?

Thanks again!

Squirrelish wrote:Enable VT-d/AMD-V: Checked

That's what did it. That's why I had that in red-bold, because it was the key parameter that needed to be enabled. The rest will make the VM perform better, but if you want to mimic an older system, that's fine...

Squirrelish wrote:What is the generic Linux template for?

Anything that's not covered by more specific templates. It's a way more "conservative" template, mainly for unknown, older OSes. Linux 1.x and early 2.x comes to mind.

Not since the 5.x series came out. Hardware is moving forward, so it's rather difficult these days to come across a computer that doesn't support VT-x/AMD-V. The software emulation has been gradually phased out and moving forward will be more and more so.
