Hi Keir,

I confirmed that the problem was fixed in the changeset 11760.
Thank you.

Then, the kernel of domainHVM panicked and outputted a message

That's a nasty race caused by netfront not waiting for the backend to reach
InitWait state before reading its advertised features. Since this is a domU
guest issue I'd like to have it fixed for 3.0.3. I've put a fix in
xen-unstable as c/s 11755:7da100019e00 and I'll also do a 3.0.3-rc5 shortly,
since this touches some moderately complicated code.
