Error message when I try to run a virtual computer
Solution 1:
The error message is very clear in this case. Your CPU virtualization options are turned off in the BIOS.
You need to reboot in to the BIOS and Enable VT-x.
According to the manual: http://h10032.www1.hp.com/ctg/Manual/c06002345
"Turn on or restart the computer, quickly press esc, and then press f10."
Under the System Configuration Tab. Check if there is Virtualization Technology listed.
Enable it.
