[whoops, my original reply didn't go to the list - fixed]

So you didn't have the type=ioemu anyway - oh well.

One minor point (that might not have any effect):

I think that vif line should probably be written like:

vif=['type=paravirtualized, mac=00:16:3E:30:E1:32' ]

The quotes either side of the comma should be removed to make it a
single string.

I think...

vif=['type=paravirtualized', 'mac=00:16:3E:30:E1:32' ]

...will actually be creating two different interfaces - one with the
type setting and a second one with the MAC setting. The
paravirtualized setting might not have been applied to your actual
interface, but I don't know that will actually make any difference
anyway.
