According to [1], when a network contains more that one IPv4
subnet, they are returned in the 'classless-static-routes'
DHCP option, regardless of whether DHCP is enabled for them
or not.
However, the get_active_networks_info() method used for
synchronizing networks after the dhcp agent restarts filters
subnets with "enable_dhcp=True", which differs from the
get_network_info() method. This will block VM access to
other VMs in the dhcp disabled subnets, even though they are
in the same network. This is visible by looking at the "opts"
file before and after a restart.
Change the dhcp agent to ask for all subnets in its
get_active_networks_info() RPC call by adding an
enable_dhcp_filter argument to toggle the behavior, with the
default being True to not break backwards compatibility.
