Cannot start VM bridged to a VLANs when another VM bridged to another VLAN is already running.

Windows Vista Business 64bit host SP2

I have 3 VLANs on an Intel PRO/1000 MT Desktop Adapter lan card.
I have installed the Intel Proset drivers for the NIC v14.3
They enable me to have each VLAN with its own virtual NIC in the form of for example: Intel(R) PRO/1000 MT Desktop Adapter - VLAN : VLAN2018 (The only way to use VLAN in Windows I know of)
If I start a virtual machine bridged to one of the Virtual VLAN NICs it is OK, everything is working
I can also start more virtual machines bridged to the same Virtual VLAN NIC
But the problem is when I try to start a virtual machine bridged to a different Virtual VLAN NIC,
while those VMs bridged to first Virtual VLAN NIC are still running.

I get a crash with message: VERR_INTNET_INCOMPATIBLE_TRUNK

Detailed message from logs: The network already exists with a different trunk configuration.
567 00:00:00.855 ERROR [COM]: aRC=E_FAIL (0x80004005) aIID={9511bc54-15ee-4ddf-808e-472aba03809c} aComponent={Console} aText={Failed to open/create the internal network 'HostInterfaceNetworking-Intel(R) PRO/1000 MT Desktop Adapter - VLAN : VLAN3024' (VERR_INTNET_INCOMPATIBLE_TRUNK).

I tried Virtual Box version 2.2.4-47978 and also latest beta 3.0.6_BETA1-51790 still the same
The only difference is that 2.2.4 locks up hard after a couple of VLAN crashes and I need to reboot my host.

For example:
start VM1 bridged to VLAN1 - OK
start VM2 bridged to VLAN1 - OK
start VM3 bridged to VLAN2 - CRASH!!!

Other example:
start VM1 bridged to VLAN1 - OK
start VM2 bridged to VLAN1 - OK
stop VM1 and VM2
start VM3 bridged to VLAN2 - OK

Anyone has this same problem? Any workarounds?

I could be able to solve this I had the option of doing VLAN tagging inside my guests. Bridge them all to the physical NIC and then tag traffic inside each one guest differently. I tried to install Intel PROSet package for the Intel Desktop Pro/1000 MT NIC inside one of my windows XP guests. I got Blue Screen. The Intel driver itself can be installed separately and is working, but the advanced networking services that includes VLAN and teaming is not. So I am completely stuck here. Some help anyone? Please?

I solved my problem, If somebody has the same, please see - http://forums.virtualbox.org/viewtopic. ... 38&p=97841
