Hello,

I installed the last version of Virtualbox in a Windows 7 system, 64 bits. The Guest system I want to use is a Xubuntu system I have downloaded to my desktop in disk image format (called "CMG-biotools", if anyone out there has been using it). I've been following the instructions of the writer of this system. I was also able to set up a shared folder in Virtualbox. However, when I tried to set it up also in the virtual computer through the terminal, I got an error. I also noticed that every time that I would close the virtual computer or Virtualbox or turned off the computer, the next time I had to define the Guest system storage again. So I though I should delete this virtual computer and re-install it. But this time, when trying to start the virtual computer to install the Guest system etc., I got this error message:

Failed to open a session for the virtual machine CMG - biotools.

VT-x is disabled in the BIOS. (VERR_VMX_MSR_VMXON_DISABLED).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

I uninstalled Virtualbox from my computer through the Ctrl Panel, re-installed it again, trying to re-install the virtual machine and got the same error.

I should mention that in the mean time I added 4 Gb of memory to the computer. Could this have changed any configuration in the BIOS? I did not do it myself, so I can't really say if someone touched somewhere else in the system and changed some configuration.

I'd really appreciate some help here

I searched the forum for this error. There is one thread about it, but no answer. If I should send a Log or something else, please let me know how to find it.

Thanks!

There actually about 2760 results according to Google. The VirtualBox message is very helpful. VT-x is disabled in the BIOS. Read on your computer/motherboard documentation how to enable it.
