Description of problem: while a virtual machine is running. each attempt to display it in the graphical console causes virt-manager to quit.

Version-Release number of component: virt-manager.noarch 1.5.1-1.fc28

How reproducible: assumed your laptop has a dedicated graphic card.

Steps to Reproduce:
1. Execute following commands –mentioned in instruction at http://blog.wikichoon.com/2016/05/spice-openglvirgl-acceleration-on.html– (provided here with outputs):

$ virt-xml --connect qemu:///system fedora-28-P-NFS --confirm --edit --video clearxml=yes,model=virtio,accel3d=yes

2. Launch Virt-manager using the default option (libvirt URI: qemu:///system):
$ sudo virt-manager

3. Verify that respective hardware devices were created in virt-manager (see attachments).

4. While the graphical console view is selected, power on the virtual machine.

Actual results: At step 4. ABRT notifier reports 'virt-manager quit unexpectedly', 'The application encountered a problem and could not continue.'
https://retrace.fedoraproject.org/faf/reports/2320363/.

While virt-manager is relaunched, in Manager view, the virtual machine appears to be running. Each attempt to display the virtual machine in the graphical console causes virt-manager to quit.

Expected results: virtual machine to be displayed in the graphical console without need for launching virt-manager itself using Dedicated Graphic's card option.

Additional info: In step .2, instead of executing the command 'sudo virt-manager' executing a possible command –unknown of me– that would be equivalent to the context menu available in Gnome 3 'Launch using Dedicated Graphic's card' (see attachment)  or use the one in Gnome then. Doing so, virt-manager allows the virtual machine to be at last displayed in the graphical console.

In documentation Virtualization Deployment and Administration Guide (Last Updated: 2018-08-23) at https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/pdf/virtualization_deployment_and_administration_guide/Red_Hat_Enterprise_Linux-7-Virtualization_Deployment_and_Administration_Guide-en-US.pdf, 

In step .1, used commands are presently missing, as well as the one that would illustrate a launch using dedicated graphic's card option.
