The hypervisors do not communicate with engine, engine communicate with them,
so you can safely reboot the engine host.

Since el7, you don't need to reboot anymore after your kernel upgrade,
kernel is hot patched.

"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.
