Hello Xlord,
The CPU does have VT support and I already have the nested KVM enabled.
Checking the Linux Kernel release notes I saw that the nested kvm feature
was implemented in 3.10 but he EPT support is in 3.12.
So Centos 7's kernel which is 3.10 does have the EPT support? Is there a
way to check that the EPT support is available in the kernel?
Thank you,
Laurentiu

https://lalatendu.org/2015/11/01/kvm-nested-virtualization-in-fedora-23/ which
should be very similar with CentOS and CentOS 7 already capable with on with KVM
Nested EPT with CPU pass-through options supported. Hope that helps &
cheers!!
