Note
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 Chapter 23, Remote
management of 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 the virt-manager sticky key capability to send these
sequences. To use this capability, 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. You can then send Ctrl-
Alt-F11 to the guest by entering the key sequence 'Ctrl Ctrl Ctrl Alt+F1'.
Note
Due to a limitation of virt-manager, it is not possible to use this sticky key feature to send a
Sysrq key combination to a guest.
