Re: Centos 7 newer kernel needed

["-=X.L.O.R.D=-" <xlord.sl@xxxxxxxxx>]

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 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
