First I installed Tiny Core Linux on the VirtualBox for the Ubuntu 16.04.

Then, I set a develop environment for Tiny Core Linux with command as shown below.

Code: [Select]
$ tce-load -wi compiletc
I made some simple file open programs with C and C++, and it seemed to work well.



However, someday, after the ubuntu sleep mode, Tiny Core linux on the VirtualBox was broken with an Error code below.



Since then, Tiny Core Linux has not been executed. I have been searching some solution with Google search, but those are not helpful.

Reinstalling of VirtualBox and Tiny Core Linux isn't the solution, too.

If there is any solution about this issue, please tell me.

Googling with your error code, I found a post (written in 2012) suggesting

1. Remount VirtualBox module:
Code: [Select]
/etc/init.d/vboxdrv setup
2. Check out if the virtual machine would boot:
Code: [Select]
vboxmanage startvm <vmname>
3. Turn off the virtual machine:
Code: [Select]
VBoxManage controlvm <vmname> poweroff
4. Retry the virtual machine normally.

I use virtualbox on windows 7,
usually if a virtual machine does not boot,
update virtualbox and the modules would solve the problem.
