HI,
Is the CentOS 7 PV kernel available? I installed latest CentOS 7 & I found out that it is a HVM guest.
So, if we wanted to have CentOS PV guest for CentOS 7, is there any specific steps to follow? or the same kernel will work as both PV & HVM?

The CentOS 7 stock kernel is Xen PV enabled.

Thanks for the reply.
How to know that the CentOS 7 kerenel is whether PV or HVM? When I searched about it, I found the following link, where the kernel type us determined from the 2 following commands 1. uname -r 2. lsmod | grep xen If both have "*xen*", then it is PV, if lsmod returns something but not in kernel name then its PV-HVM, else its HVM
From what I understand, the first command never have "Xen" extension to the
CentOS 7 kernel. So, can I conclude that there are only 2 types of kernels in case of CentOS 7 onwards, i.e PV & HVM.

you've asked this a bunch of times and have been told over and over, IT SUPPORTS BOTH.
if you run c7 in a HVM, it will run as a HVM system. if you run it in a paravirtualized environment, it will run as a PV system. its the HYPERVISOR you're running it under that determines what mode its running in.
and your link? thats talking about centos 5.2, which is rather old, like 2008.
