A note on security and VNC
VNC is considered insecure by many security experts, however, several changes have been
made to enable the secure usage of VNC for virtualization on Red Hat enterprise Linux. The
guest machines only listen to the local host's loopback address (127.0.0.1). This ensures only
those with shell privileges on the host can access virt-manager and the virtual machine through
VNC.
Remote administration can be performed following the instructions in Chapter 19, Remote
management of virtualized guests. TLS can provide enterprise level security for managing guest
and host systems.
Your local desktop can intercept key combinations (for example, Ctrl+Alt+F11) to prevent them from
being sent to the guest machine. You can use virt-managersticky key' capability to send these
sequences. You must press any modifier key (Ctrl or Alt) 3 times and the key you specify gets treated
as active until the next non-modifier key is pressed. Then you can send Ctrl-Alt-F11 to the guest by
entering the key sequence 'Ctrl Ctrl Ctrl Alt+F1'.
SPICE is an alternative to VNC available for Red Hat Enterprise Linux.
