With drop the newtork I mean that both ping and SSH toward the guests throw a Destination Host Unreachable. When the network drops, running `ifconfig` from inside the guests keeps showing the same, correct data as before the drop, like IP address, MAC and netmask. But after the ethernet cable

Consider whether you're talking about layer 2 or layer 3 network connectivity (test). If this is a Workgroup, consider whether you have a Browse Master issue. Consider whether your issue is a name resolution issue. I assume the connection is bridged? Try NAT if it doesn't make a diff to you.

Thanks Vlad, apparently everything is fine on `ifconfig` after the ethernet cable is unplugged and re-plugged; I don't see what is wrong: Before unplugging the cable – guests network works: — root@debianBunker:/home/davide#

The problem is still alive, and kicking. Whenever the ethernet cable is detached or the network (ADSL modem/router) goes offline for a brief moment, the guest VMs remain unable to reconnect, as shown in the previous post. I have no idea how to move around this. -- Davide
