I'm currently investigating setting up few Xen servers.  I've noticed
that currently live migration of Xen's require you to use a network
based storage system.

Using network is likely the cheapest and most convenient one unless you happen to have
FC already.

If you are the boss, used 1G FC is quite a bit cheaper (and faster) than used 1G Ethernet.

However, most bosses refuse to use used stuff; and some people think that commodity Ethernet will scale faster than commodity FC, so it's better to just run Ethernet everywhere. (these people may be right; my point still stands that 1G fibre channel, bought used, gives you better storage performance per dollar than 1G Ethernet)
