Dear Laurentiu,
Please check below info since assume your CentOS7 box CPU processor already VT
supported in advance.
1) Checkpoint #1: Hardware and Kernel modules
a. cat /proc/cpuinfo | grep vmx
b. cat /sys/module/kvm_intel/parameters/nested (if “N” then go to
checkpoint #2)
2) Checkpoint #2: Assume your CentOS box support
a. echo 'options kvm-intel nested=y' >> /etc/modprobe.d/dist.conf
b. modprobe kvm-intel
3) Checkpoint #3: Verification
a. Reboot yout CentOS box
b. cat /sys/module/kvm_intel/parameters/nested (if “Y” then you can carry
one process the KVM installation.
PS: Source:
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!!

Subject: [CentOS-virt] Centos 7 newer kernel needed
Hello,
I am looking for a Linux kernel for Centos 7 that implements a feature
introduced in kernel version 3.12:
"nested EPT support to KVM's nested VMX."
If anyone has used this feature with Centos 7, please let me know.
Laurentiu
