I'm writing a script to start qemu virt-machine.

I want to share a folder of host with the winxp guest in qemu virt-machine.
My vm uses NAT networking, the ip address of bridge interface is 10.3.232.1.
I'm using a samba server for file sharing between PC, so I want to start a dedicated samba server for my virt-machines.

Problem occured when doing socket binding operation:
The main samba server binds to 0.0.0.0:139, and the dedicated samba server needs to bind to 10.3.232.1:139. The binding of the dedicated samba server failed.
I know this limit, although I don't understand why it's there.

How should I do this? please help!

Solution in my head currently:
1. winxp only recoginize port 139, so I can't modify the port number of the dedicated samba server,
2. Can I isolate the bridge interface and other interfaces using cgroup?
3. In my script, I can use the main samba server to share the fodler to virt-machine, but it'll be complicate, needs dynamic samba config modification, netbios alias etc.

How does virtual-box implement its "share-folder" feature?
