VLAN - VirtualBox - KVM switch for closed network monitoring

[apri]

Hi...

kindly need your all help..
I'm trying to establish new monitoring system in my company, but I need to collect more information if I'm able to do it or not.
Basically, this monitoring involve VLAN, Virtual Machine, and also KVM switch(for remote purpose).
Please see my attachment for more clearer issues.
If you had similar issue and already found the solution, please share it with me.

Any comment is very appreciated.

Thank you very much..

cheers..

If I understand clearly, you want to do VLAN tagging after the host, depending on the VM talking?
Do the VMs need to be aware of the VLANs at some point at all? If not, I fail to see how this is related to Virtualbox.
