mail
we will configure this system with a mail server
this server will later be configured to forward its mails to another mail account

* write a ssection about spice and TLS, check this to set up the TLS certificates on kvm02 /etc/libvirt/qemu.conf

http://thomasmullaly.com/2014/11/16/the-list-of-os-variants-in-kvm/

take a look at this package : osinfo-db		  * Mailserver
 * Firewall
 * Monitoring diskspace
 * Network planning
 * Keyscript should try thrice
 * NTP servers are getting the time from themselves, thats not optimal. https://ubuntuforums.org/showthread.php?t=1513500 only 1 iburst server may be the solution.
 * Create a page about manual DNSs updates and nsupdate
 * Spice and TLS write a ssection about spice and TLS, check this to set up the TLS certificates on kvm02 /etc/libvirt/qemu.conf
 * KVM guest types are in package osinfo-db
 * move gluster07 to dedicated hardware, so the arbiter works as expected.
 * Do some pages on optimizations, this is both network, diskio etc. BUT redundancy and stability comes first.
 * Do some pages on security, for now redundancy comes first
