I have an issue with VLANs that was in XCP 1.0.0 and also persisted after the upgrade to XCP 1.1.beta.  I updated to the beta because I spoke with someone in #xen-api that suggested that a fix to the issue would be implemented in 1.1, it seems it may have been overlooked or I have a different issue.

Currently the server has 2 network cards:

00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 05)
02:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection

eth0 is the designated as the management interface and is connected to a port on VLAN 193
eth1 is the interface used by the VM's and is connected to a trunked switch port to provide VLAN access to the VM's

Before moving eth1 to a trunked port without vlanning I could ping it's ip address and ssh to it.  After moving it to the trunked port I have no connectivity to it whatsoever.  The only way I can get a response from it is to ping the static IP on the local machine.  The VM's are using the interface on the created VLANS almost perfectly however they sometimes exhibit strange behaviour such as loss of connectivity when connecting to another machine crossing over a vlan.

I setup my vlans using the XenServer guide here is the output of pif-list:

I suspected that the issue may lie here:

************************************************************************************
uuid ( RO)                  : e602777f-b4e9-e231-7858-81189c47c434
                device ( RO): eth1
    currently-attached ( RO): true
                  VLAN ( RO): -1
          network-uuid ( RO): df87728a-e4a7-a16e-9f8c-c4c4c26dc35f
************************************************************************************

where the eth1 interface is assigned a VLAN value of -1 when it should be on the 201 network.  When I try to do

xe pif-param-set uuid=e602777f-b4e9-e231-7858-81189c47c434 VLAN=201

I get:

Error: Field 'VLAN' is read-only.

How can I assign the interface to the correct VLAN so I can use it again for traffic to the server?
