I'm running kdm for my display manager and use KDE as my desktop.  I've ssh'd into the system before logging in and I see....

[egreshko at f20f ~]$ ps -eaf | grep dbus-daemon
dbus       638     1  0 Jul09 ?        00:00:06 /bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation

after login and KDE desktop with no konsole started....

dbus       638     1  0 Jul09 ?        00:00:06 /bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation
egreshko  7131     1  0 08:46 ?        00:00:00 /bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session
egreshko  7707  7699  0 08:46 ?        00:00:00 /bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3

I then started 10 "copies" of konsole from the "Application Launcher".  But, I still only get....

 [egreshko at f20f ~]$ ps -aux | grep konsole
egreshko  8180  0.5  5.4 682800 69572 ?        Sl   08:54   0:01 /usr/bin/konsole

and

[egreshko at f20f ~]$ ps -eaf | grep dbus-dae
dbus       638     1  0 Jul09 ?        00:00:06 /bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation
egreshko  7131     1  0 08:46 ?        00:00:00 /bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session
egreshko  7707  7699  0 08:46 ?        00:00:00 /bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3
