I'm not sure having the inter-host migration is best implemented on the
autotest-client side. Actually this is one of the few tests I think belong to
the autotest-server side.
On the other hand it is pretty simple to implement it here. So I think we'd
better try first implementing it as a server test, and apply it to the client
side only as a second choice.
A few (minor) problems with it running on the client side:
1. We do not know what the other host is running (what version?, kvm-modules
loaded? etc.)
2. There may be a conflict between a running local guest running on the remote
(if it allowed to run tests while being a migration destination), and the remote
guest.
3. There may be a conflict between two remote guests running a migration test on
two different hosts.
3. get_free_ports run on the local machine, but expected/assumed to be free on
the remote machine too.
4. For a migration to be successful, the image(s) must be shared by both hosts.
On the other hand, when installing a guest OS (e.g. Fedora 8) on both hosts
(let's assume they both are running fc8_quick) we want different images on
different hosts.
These are all can be solved easily by non-trivial pretty simple configuration on
the server. One can configure the "remote" migration to run as a separate tests
to all other tests.

Uri.
