The place where we mention the qxl driver is in the Administration Guide in
Table 15.3. Red Hat Enterprise Virtualization Guest Drivers

with information about qxl, and what it does.
The site linked above contains a KBase article called "Configuring multiple monitor support for RHEL guests running on RHEV".
