Maybe there you can disable "autostart" property and also remove attached pci devices. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

To edit the xml file and remove the devices assigned to sys-net, look for lines like in the sys-net section - delete those lines. MAKE SURE you have a copy of that file somewhere safe before editing. Then restart - sys-net should start but wont be stealing the usb devices. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
