Is it possible to monitor and gather statistics in realtime (CPU,
memory, HDD, network, … – something like dstat) of guest systems
with libvirt through console from host system (KVM based)? If yes, do
those guests need to be created through libvirt?

virt-manager has some of this built in, but if you want more detail, look at nagios-virt. Alternatively, you can monitor it by installing the same tools (nagios, ZenOSS, etc) on the guest that you'd use on a non-vm system.
