Oracle VM: Base memory greyed out


I am trying to stop the VM VirtualBox to be able to change the base memory but it is still greyed out.


Can i enable the change please? Thank you


Master Mentor



VirtualBox requires virtualization support from the CPU (and enabled in BIOS/UEFI). So, there's an invisible checkbox in that page that gets locked to "checked"

It's likely that your system does not have both of them (i.e., the CPU does not provide virtualization support [Intel VT-x or AMD-V], or it does but not enabled in BIOS/UEFI).

Can you share the screenshot?


Thank you for your reply.


I am not sure which screenshots you mean but i have done these for you. Hopefully that clarifies the situation? 


For info, here are my pc information:

  • Processor: Intel(R) Core (TM) i5 -4210U CPU @ 1.70 GHz 2.40 GHz
  • Installed RAM 8.00GB (7.89 GB usable)
  • System type: 64-bit operating system x64-based processor
  • Windows 10 home (version 2004)
  • OS build: 19041.867
  • Capacity 910 GB (Free 655 GB)
  • File System: NTFS

Please let me know what you think. Especially if i can run Cloudera express with my pc



Can I get some help on the issue below please

Master Mentor

Sorry I wasn't available for a while, What I meant was the BIOS , this is a much older server but it should be outright  clear once you enter the BIOS

I see in your screenshot it's set to HyperV can you also boost the CPU to 2 .
Please let me know
