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 (dom0)'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
management of virtualized
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'.
