What I don't understand is how and why does the stopping of a vserver
influence a network interface of the host ? As the networking is (by default)
the responsibility of the host and the guest has no reconfiguration
capability I presumed it had no influence on it. The biggest problem is that
it brings down the default route with it, cutting off the host from machines
reachable through the gw.

the interface file of the guest is empty, the host has:
auto lo
iface lo inet loopback
# This entry was created during the Debian installation
# (network, broadcast and gateway are optional)
auto eth0 eth1
iface eth0 inet static
address 94.152.112.53
netmask 255.255.255.0
gateway 94.152.112.1
iface eth1 inet static
address 10.10.10.53
netmask 255.255.255.0
The eth0:0 gets added in dynamically (as it is from a failover address pool on
the same subnet) - ifconfig eth0:0 94.152.112.55 up.
