Virtualbox follow-up:

Although Virtualbox worked, I got a problem when I increased the number of CPUs to 2 in my virtual machines.
I got the following error message:

Failed to open a session for the virtual machine Mint. VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED).

After some search, I came to know that I need to enable virtualization in my motherboard BIOS.
After doing so, I got another error message instructing me to do the following:

           sudo /etc/init.d/vboxdrv setup

I did that and now Virtualbox is running my virtual machine on multi-processors.

Again: I am using Asus P8Z77-V LX motherboard with I7 3770K + 16GB Ram + HD 4000 GPU on Ubuntu 64
uname -a result:
Linux Asus 3.4.0-030400-generic #201205210521 SMP Mon May 21 09:22:02 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

BTW: Could it be the freezing problem is due to turning virtualiztion OFF in the BIOS ?
