However, when starting the virtual machine I get the following error:"This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your CPU."I have the minimum spec as stated in Pega's VM User Guide. Please can someone confirm whether the spec listed is correct?Many thanks,Mike.***Updated by moderator: Lochan to move post from PSC to Pega Academy*****Moderation Team has archived post**This post has been archived for educational purposes.

Pega - please can you update your documentation or virtual machine image accordingly. Many thanks, Mike.

In my case, in virtual box "ubuntu-64 bit" option is not available in the system setting of the virtual box. Only "Ubuntu-32" bit available. Please let me know on how to reslove this error. Thanks in advance.

The virtualization mode should be enabled on the BIOS setting.
