I have a quad-core, 16GB, virtualization enabled in BIOS, CPU is i7 3770

I'm not sure what is causing this error where when you try to start a VM it just freezes.
As in a complete OS freeze, have to restart.

I was following this thread here as I had this error previously:
under ask ubuntu: 900794/virtualbox-rtr3initex-failed-with-rc-1912-rc-1912

I tried to run Ubuntu and Debian

Thanks for any hints/suggestions

edit: not sure if this is related to me, I'll try a 32bit guest os

I think you're running "VirtualBox 5.0.40_Ubuntu" as seen from the "VBoxManage --version" command. If that's the case (even if not), completely remove/uninstall/delete/purge that version and install the latest test build.

@socratis

Okay I will try that.

I'm not sure I was reading a thread mentioned above about hyper-v and that virtualization has to be able to access this to run. I don't know if my computer by having that enabled is using it so Vbox can't use it?

At any rate I'll try again. I did purge completely and then installed what I thought was the right one.

It would be sad if I couldn't get Vbox to run on this computer as I bought it with more memory specifically to run Vbox haha. Could consider alternatives/docker/(varnish?) and others (kubernetes) haha not being completely serious as my needs are pretty basic/don't need multiple instances, just running specific web stacks.

Thanks

From the time that I replied to you, until now, 5.2.6 is out, so try that one: https://www.virtualbox.org/wiki/Linux_Downloads

I'm trying it out but I think I'm missing some main problem if it immediately freezes when I try to start it.

I have ran Vbox on a desktop running Ubuntu as the Host os and then another Ubuntu os as the guest os so it's doable, just not sure what's up with my desktop.

I don't have a Windows OS on it.

Edit: OOHHHHH!!! No freezing, still typing as vbox runs.

Thanks man!

Grabbed the Ubuntu Xenial release for 64bit and used dpkg install

Nice!

Glad you got it going. Marking as [Solved].

Sorry for the "me too" post, but I've been fighting this all day, with the exact same host hardware configuration as the original post, and I just had to bump this up.

The default virtualbox that comes with Ubuntu Xenial (5.0.something) will NOT work with a 64-bit guest. Not sure what the root cause is. I went through a bunch of iterations of BIOS configs and virtualization settings. Every time I launched the VM, it would hard-lock the host OS requiring a cold reboot. No logs were generated. No errors reported.

To fix it, I purged the distro-installed virtualbox. I then Installed 5.2.6 form the website, rebuilt the kernel modules (done simply by rerunning /sbin/vboxconfig), and I'm back in business installing win7 64 bit. Well done.

For searching, the host is: Dell Optiplex 790, CPU Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz, running Linux Ubuntu 16.04.3 (xenial).

@davidd6sr
It had nothing to do with your specific hardware, it had to do with the fact that you were running the Ubuntu fork (their latest is 5.0.40_Ubuntu) with the latest Jan/2018 kernel updates. That causes a freeze on the host. No matter the host...
