How safe is running a domU sda1 off of an image file located on an NFS?

I am thinking about setting up a WEB server for hosting our internal
web apps on
a domU.  I am thinking about creating the root disk image on the NFS
folder so that when i do i live migration the disk image is available
on the new server.

is this safe?
how is the performance?
is there a better way to do this without investing in SAN?

You should definitely look at iSCSI. It's a "SAN solution" but doesn'trequire any special hardware, and is well supported under Linux & Xen.
