Hi

you can look here for a jack guide:
https://fedoraproject.org/wiki/JACK_Audio_Connection_Kit

http://docs.fedoraproject.org/en-US/Fedora/18/html/Musicians_Guide/sect-Musicians_Guide-Using_JACK.html#sect-Musicians_Guide-Install_and_Configure_JACK

http://docs.fedoraproject.org/en-US/Fedora/18/html/Musicians_Guide/index.html

VMPK is available in fedora "sudo yum install vmpk" but it is only a 
MIDI keyboard, you will need to connect its MIDI out to a programs MIDI 
input in Jack, and route the Audio outputs of this program to your 
system outs.

Alternatively (easier) you could try installing yoshimi or ZynAddSubFx 
which both have built in keyboard.
