What management tool are you using that the syntax is "source_device=eth2"?
Are you maybe just paraphrasing your config, and what you actually have
is something like this?:
<interface type='direct'>
<source dev='eth2'/>
...
</interface>
?
If so, the way to make this easily migratable is to create a network on
both hosts that points to the desired physical device, e.g. on host 1:
<network>
<name>direct-net</name>
<forward mode='bridge'>
<interface dev='eth2'/>
</forward>
</network>
and on host2:
(same thing, but use 'eth1')
After net-define-ing the networks, you'll need to net-autostart and
net-start them. Then in your guest's interface config, you would use this:
<interface type='network>
<source network='direct-net'/>
...
You will then be able to migrate from one host to the other without
needing to modify your XML during the migration.
