[virt-tools-list] [PATCH] virt-manager: Fix VNC connection on hypervisor without GraphicsFD

[Mikhail Feoktistov]

Function virDomainOpenGraphicsFD() from libvirt can return -1
But in this case libvirt-python will raise an exception.
We should handle this case and return -1 as invalid FD.
In commit 5c451b64 Viewer._open() there is a code to open
graphics console in case of invalid GraphicsFD.
