Description of problem:

Following scenarios does not work
1) When running virt-manager, access to serial console of any guest from console is not possible as virt-manager holds session for the console.

2)If trying to view serial console in virt-manager when console is opened somewhere else, got error message (correct behavior). However, after closing
console session, virt-manager still reports active session.

3) When running virt-manager and access serial console using virsh console --force, virt-manager serial console tab is stuck even after closing another session (not reconnected).

Version-Release number of selected component (if applicable):
virt-manager-0.10.0-4.git79196cdf.fc20
libvirt-client 1.1.3-2.fc20

How reproducible:
Always

Steps to Reproduce:
1. Create and run guest with serial console
2. Try to access it from virt-manager or console

Actual results:
virt-manager create serial console session on background on start (guest or virt-manager, whatever happens first) and do not update it.

Expected results:
virt-manager create serial console session on demand, update when serial console
is requested again.
