Startup problems for Linux Guests on Windows Host - VERR_CPUM_RAISE_GP_0

[MK866]

Hi everyone,

I am currently experiencing persistent problems in getting both Ubuntu and Opensuse Linux guests to boot (more than once) on my new laptop.

Every time I boot up the virtual machine the machine starts, shows some initial loading screens and then ends up at a black screen with a cursor for Ubuntu and at "Loading initial ramdisk" for OpenSuse.

General machine settings in short:
4 CPU cores (8 @ Host)
4096MB RAM (32GB @ Host)
128MB Video Memory

Both machines exhibit the same error message shortly before or at the point of halting:

Ubuntu (including first messages of the shutdown)

I tried googling for any description of the error but the results were a bit cryptic.

I attach two log files for two virtual machine images that I downloaded - virtual machines that were installed by myself show the same behavior.

I would really appreciate any indication as to what settings I need to change / what I need to fix to get them running on the new hardware. The old laptop always worked absolutely fine with Virtualbox

Thank you in advance!

Hyper-V is enabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

Thank you so much - this fixed the issue

I apologize for not recognizing this as a common problem ... I never had any issue in this regard despite using probably half a dozen PCs with Virtualbox

No problem. I borrowed scottgus1's standard answer to answer in his place, because you maybe distracted him with naming the error code (VERR_CPUM_RAISE_GP_0).

Seriously, it's good to have the error code in the title, for other people to find in the future Google searches.
