The bulk of our users run Windows XP (32 bit) clients accessing either Win
XP or Win 7 guests. Myself and the other sys admin run Fedora 18 and
Fedora 19 desktops respectively. We all experience the time out problem.
Between the client PCs (Windows and Fedora), we have a pair of firewall
clusters of different brands. I am the primary administrator of the "inner"
firewall cluster but have no visibility of the outer firewall cluster.
Basically we have:
Client PCs --- Outer FW cluster --- Inner FW cluster --- RHEV-M and
RHEV-H (actually fat RHEL)
I have ensured that the FW cluster I maintain does not do timeouts on idle
connections. I can ssh into a RHEL VM, and leave the SSH session idle for
days without a disconnect. Once I get a SPICE session to a VM, if I don't
use it for about 15 minutes or so, it either freezes completely (the SPICE
session, not the VM) or disconnects with "unable to connect to the graphic
