In windows 10, inside Virtualbox running centos 7 when I try to run the docker-machine command, it gives the below error

 docker-machine create --driver=virtualbox vbox-test
 Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"

My computer has Virtualization enabled. How can I enable this in Virtualbox?

From windows I see Virtualization enabled.

wmic cpu get VirtualizationFirmwareEnabled
VirtualizationFirmwareEnabled
TRUE

  • to be clear: your host is win10, your guest is centos7, and you're trying to run `docker-machine create` on the guest? virtualbox doesn't support virtual VT-x (there's a [feature request for it](https://www.virtualbox.org/ticket/4032)). – quixotic Mar 15 '17 at 03:52
  • As pointed out, VituralBox doesn't supported nested virtualization, which is required for Docker to function. If you have Windows 10 Professional, Hyper-V supports, nested virtualization – Ramhound Mar 15 '17 at 04:06
  • Yes, Centos guest os inside the vituralbox. @Ramhound thanks for the pointer looks like now I need use doocktool box to try docker-machine. thanks for the information. – sfgroups Mar 16 '17 at 00:04
