问题
I have the following scenario. I am running a Ubuntu 14 LTS in a Virtualbox on a Windows 10 system.
Within this ubuntu I would like to install a Virtualbox where I need to run a custom docker ISO image.
Now, the problem seems to be the fact that the Virtualbox within the Ubuntu doesn't have VT-X/AMD-v enabled.
VT-X/AMD-v is enabled on my system, all works well. How can I enable it within the second virtualbox?
Windows10-> VirtualBox(VT-X/AMD-v OK)->Ubuntu->Virtualbox(VT-X/AMD-v missing)
回答1:
Nested virtualization is not supported by VirtualBox. If nested virtualization is important for you, I suggest you try other virtualization applications that support it (e.g. KVM or VMware ESXi / VM player).
