Subject: 802.1q VLAN tagged trunk port required?

Hi I am trying to get the 4.0 setup, previously when I installed 3.x.x =
version few months back I do not remember having to setup vlan for the =
Host system. But with 4.x it looks like there needs to be vlans setup? I =
have not worked with vlan much before. It appears that in order to =
support vlan properly the switch must have 802.1Q vlan and trunk support =
so that it can pass the tagged frames properly. My question is, if I am =
understanding the requirement for a switch correctly in order to run =
Cloudstack with basic networking.

If I follow the doc and create the vlan, I can not connect/ping anything =
to on the primary network/lan. Other machines on the lan can't see the =
host either.


Primary net: 192.168.10.0/255.255.248.0

Here is my /etc/network/interfaces file:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0.100
iface eth0.100	inet static
	address 192.168.10.139
	netmask 255.255.248.0
	gateway 192.168.10.254
	dns-nameserver 192.168.10.254

# Public network
auto cloudbr0

    bridge_ports eth0.200
    bridge_fd 5

# Private network

    bridge_ports eth0.300
