The server has networking, everything appears to be ok on the server's side.
But none of our VMs are getting DHCP assignments after the upgrade to v4.2

Code:
cat interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage part of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

auto lo
iface lo inet loopback
#auto eth0
#iface eth0 inet dhcp

auto eth1
iface eth1 inet manual

iface eth2 inet manual

auto vmbr0
iface vmbr0 inet static
	address  192.168.28.200
	netmask  255.255.255.0
	gateway  192.168.28.1
	bridge_ports eth1
	bridge_stp off
	bridge_fd 0

FWIW, I don't know why there's a VLAN20 - we had one at one point but it is no longer in service.
I don't see how to remove it. Is that the problem?
