This would depend on what templates you are using, and how they are configured. You can, if you wish, set custom iptables rules in sys-net and sys-firewall to restrict traffic from those qubes, or deny it completely. At a minimum there is the clockVM which will look up time. There is a function to check for updates - this is a service that you can turn off. (Look in Global Settings in Qubes Manager.) Fedora has (had?) a function to check for network connectivity. Most of these can be removed/disabled. You could run tcpdump in sys-net and capture the traffic if you want to be absolutely certain of what is happening. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
