Just as the title says I am looking to get my proxmox servers to reside on my untagged vlan which in my configuration is vlan 1. On my Xen servers I have done this with little to no issue. However when I attempt it in proxmox I am left with an unreachable network. I can put them on any other vlan and it works but cannot have it on vlan1. Am I missing something?

It just hit me that I can run it on vlan1 if it is not in a bonded interface. This may be due to running mode4 bonding. I am going to try mode6 and see what happens.
 
I encountered a similar situation with 802.3ad while back. It turned out to be a problem with how the LAGs were configured.
 
The other issue I am running into is on a mode4 bond it seems impossible to get my Dell DRAC cards to work. So I may be forced to go with mode6 afterall. If I read right mode6 will also allow full aggregate bandwidth on the bonded interfaces right? Like I have 2 gigabit interfaces it theoretically should do a maximum of 2gb/sec? Also, what is the LAGs you are referring to?
 
Does this look right for a single interface that is only a trunk? Two of my servers only have 2 NIC's and I need one to be the trunk'd interface while the other goes for SAN traffic only.

I found the way to make it work on an untagged vlan. At least it is working so far. Would someone look over this and make sure I did not mess up anything?

Code: 
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

# soon to be SAN interface
#auto eth1
#iface eth1 inet static
#

# Remove the vlan1 config from the interfaces file since it does not need to be tagged.
#auto vlan1
#iface vlan1 inet manual
#vlan-raw-device eth0

auto vlan2
iface vlan2 inet manual
vlan-raw-device eth0

auto vlan3
iface vlan3 inet manual
vlan-raw-device eth0
..............
auto vlan15
iface vlan15 inet manual
vlan-raw-device eth0

# And run vmbr0 directly on eth0 instead of a vlan
auto vmbr0
iface vmbr0 inet static
        address 10.8.1.151
        netmask 255.255.255.0
        gateway 10.8.1.1
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0

#auto vmbr1
#iface vmbr1 inet manual
#bridge_ports vlan1
#bridge_stp off
#bridge_fd 0

auto vmbr2
iface vmbr2 inet manual
bridge_ports vlan2
bridge_stp off
bridge_fd 0

auto vmbr3
iface vmbr3 inet manual
bridge_ports vlan3
bridge_stp off
bridge_fd 0
..............
auto vmbr14
iface vmbr14 inet manual
bridge_ports vlan14
bridge_stp off
bridge_fd 0

auto vmbr15
