setenforce: SELinux is disabled
Solution 1:
The kernel you are using was built without SELinux support. Using a stock kernel will not include the appropriate parts for your VPS. Rebuilding the kernel with SELinux support will cause the VPS parts to not work. You cannot use SELinux on your VPS.
Solution 2:
Your VPS runs on OpenVZ, a container based "virtualization" which has no support for SELinux. If you need SELinux, you will need to switch to another hypervisor which supports SELinux in guests, such as Hyper-V, VMware, KVM, Xen, and possibly others.
