Reassigned. - VNC is showing display only on the first run of the VM. after powering off and running the VM again, the VNC display freezes before the VM completely booted. - Running diff of VM qemu process shows that when there is no VNC display, there is cirrus-vga device that was added (please see diff.png file attached). and also inside the VM there is Cirrus VGA controller: 00:05.0 VGA compatible controller [0300]: Cirrus Logic GD 5446 [1013:00b8] Subsystem: Red Hat, Inc. QEMU Virtual Machine [1af4:1100] Kernel driver in use: cirrus Kernel modules: cirrus - Possible workaround for this issue, it to edit VM -> Console and change video type from QXL to VGA or vice versa. qemu proccess files for diff, vdsm.log and engine.log attached.

Another thing, when using virt-viewer or virt-manager the mouse cursor is invisible although mouse is present (windows are highlighted and mouse clicks are working). using TigerVNC mouse cursor is visible.

Found the reason behind it. On the first run, the XML contains no <video> tag but contains <graphics> element for VNC. Libvirt's doc says, that: For backwards compatibility, if no video is set but there is a graphics in domain xml, then libvirt will add a default video according to the guest type. For a guest of type "kvm", the default video is: type with value "cirrus", vram with value "16384" and heads with value "1". I can add a quick fix (detect that we have graphics but no video, then add <video> with type none if appropriate) if we're pressed for time, but I'd rather find the root cause (why there isn't a video element at all).
