About installing virtual machines in virtual machines

  linux, question

Vmware is installed in real win8.1

Centos7 is installed in Vmware

KVM installed in Centos7

Rhel6 installed in KVM

Prompt after starting rhel6

Error starting domain:unsupported
Configuration:Domain refugees KVM,but it is not available.Check that virtualization is enabled in the host BIOS,and host configuration is setup to load the kvm modules.

Virtualization support has been turned on in the bios of the real machine. I don’t know what else to do in other places. Please give your advice.

As you can see from the above, the virtualization support of VT-D must be turned on in the CPU for vm setup.
