You were correct about the *almost*. Great help!
Thanks very much.

you can omit the -t ext3

do not copy dev, just create it like below! You forgot to copy /boot !

this leaves you with a tmp that has wrong permissions, copy it as well or
add the necessary steps afterwards. I assume, home is empty or you do not
want to copy it?
Do you want to go from xvda image to an ext3 file system or what is the
purpose? The procedure is straight-forward and it looks like you have done
it *almost* correctly. I assume you followed an instruction that wants to
boot from an external kernel, there is a nice wiki with a lot of good
explanations about this out there. However, these instructions are nonsense
for paravirtualized CentOS/RHEL guests, probably all PV guests. You simply
copy *everything* *as is* to the new location, except for the "special
directories" dev, proc, sys.
Then you just boot the VM like normal with the pygrub boot loader. e.g.
copy the config file from your original virt-install/virt-manager created
setup, do *not* change it according to the instructions for external kernel
booting you found!
