I have CentOS 7 with Qemu/KVM and Libvirt running on a headless HP Proliant Server. Virtual hosts are managed via Virt-Manager installed on a CentOS 7 + KDE client via SSH.
Things are running quite nicely for now, I only have a few small minor details to adjust.
On my main workstation running Slackware64 14.1, I also have Qemu/KVM and Virt-Manager installed. When I launch a virtual host and switch to full-screen display, the host is a “real” full screen.
But when I do the same thing with CentOS, I don’t have a real full-screen display. There’s still two grey bars left on the upper and lower end of the screen.
Any idea how I can get rid of these and have a 100% full-screen display for a KVM host?
