Is there any command line option to assign IP and MAC addresses to the VM?. I know we can assign network device but how do we assign IP and MAC so that the VM works properly even after migration.

Subject: [Qemu-discuss] Network Migration During Live Migration
Message-ID:

Content-Type: text/plain; charset="utf-8"
Does QEMU supports network migration during live migration? By network
migration I mean migrating open connections inside the VM so when the VM
moves to a new physical host, it can still communicate with outside world
at the same fashion as it did before migration?
I'm mainly interested in this issue as I've a Web Server running inside the
VM which I use using port forwarding and I would like to know what should I
do to keep the server working after the migration?
Thanks
Azizul Hakim

I am not sure if this will be helpful:
The general concept is that the virtual machine (including
its OS and network software) should be completely unaware
that the physical computer host has been replaced beneath
it.
Thus for networking, it should have the exact same MAC
address(es), IP address(es) and connectivity before and
after. Whatever tool, script or procedure outside qemu
is used to command live migration is expected/required
to make this happen by specifying identical "inside"
network behavior (same virtual NIC model, MAC address
and virtual PCI bus location) and compatible "outside"
network behavior (e.g. bridging or other hookup to the
same VLAN).
Typically the your web server VM would be connected to
a bridged network which is available on both physical
machines and the effect would be as if you instantly
moved a physical web servers network cable from one
position in the outside network switch to another.
This way, even ongoing downloads from the web server
should not be disrupted, except for a short pause while
the migration slows down the VM and the physical network
switch learns the new path to its MAC address.
Enjoy
