Changing the memory size of a domU is not supported in the July
code.  Work to support it is underway (the ''balloon'' driver).

Adding disks to a running domU works (via ''xm block-attach''),
though
you need to kick devfsadm in the domU to make the device nodes appear
(this will be fixed).

I''ve never tested adding network interfaces to a running domU, though
it should work (the mechanism is the same as that for block devices).
