I want to know about kernel update frequency(because they are causing server reboot) for different operating systems such as Linux(CentOS, Debian, Ubuntu Server Edition), FreeBSD NetBSD, OpenBSD.

Could anyone help? I'm not trying to make a Linux vs BSD question as it is against forum rules.
First of all, I quite agree with the cluster idea.
If it is really of the question, put whatever distro you want and simple DON'T update kernel. You are not forced to apply each update of the distro. Actually in a production machine, you don't update at all, at least not automatically. If for example the "automatic" update request new version of apache, your machine will have a small down time. If problems with the new configuration files arise, then it will be big down time.

Don't update anything.

LIBGUESTFS(8)						      System Manager's Manual						     LIBGUESTFS(8)

NAME

       update-guestfs-appliance - update the supermin appliance used by libguestfs

SYNOPSIS

       update-guestfs-appliance

DESCRIPTION

       update-guestfs-appliance  creates or updates the supermin appliance for use with libguestfs. It uses febootstrap for this, therefore access
       to the package repository is needed.

       A supermin appliance contains only lists of files and directories. The contents of the referenced files are  only  copied  into	an  ad-hoc
       filesystem  whenever  libguestfs  starts a virtual machine. Therefore, calling update-guestfs-appliance is only needed after libguestfs has
       been installed or when the filesystem layouts or dependencies of needed packages on the host system have been changed.

FILES

       /usr/lib/guestfs/make.sh (the script that does the actual work),
       /usr/lib/guestfs/supermin.d/hostfiles
       /usr/lib/guestfs/supermin.d/base.img

SEE ALSO

       guestfish(1), guestmount(1), febootstrap(8), febootstrap-supermin-helper(8).

AUTHOR

       update-guestfs-appliance and this manual page were written by Hilko Bengen <bengen@debian.org>, for the Debian project (and may be used	by
       others).
