"kernel is hot patched ", mm which version of CentOS use your? i use: ovirt-engine-3.6.6.2 over centos 3.10.0-327.18.2.el7.x86_64 and periodically updates the kernel.
I've seen: kpatch and ksplice, What is your implementation? Yes, it was about kpatch, but you're right, kpatch must be manually applied from a diff source kernel, and is not applied by default. http://jensd.be/651/linux/linux-live-kernel-patching-with-kpatch-on-centos-7

Hello, friends, it is safe reboot my host after update the kernel in my centos 7.2 x64, the ovirt engine 3.6 run over this centos in a independent host. which it is the frequency at which the host/hypervisors communicates with the engine oVirt? The hypervisors do not communicate with engine, engine communicate with them, so you can safely reboot the engine host.
