Very EC2 centric, and most are already known, but I'll repeat my pet
issues here for completeness:
* some modules are purposedly not shipped in the virtual kernel to save
space, I'd personally prefer if Ubuntu kernel features were identical
inside and outside the cloud, but I wouldn't mind if I had to install
an extra package to get modules which would have been striped out;
see LP #732046
* I didn't test on natty, only on maverick, but it was quite manual to
install a different kernel flavor in an EC2 instance and get it
picked up by pv-grub
* would be nice if we weren't using GRUB 1 anymore; it's a bit
confusing to end up with both in instances
* the server kernel in maverick (not the virtual one) was lacking some
features to work as a complete drop in replacement for the virtual
one and provide Xen console, reboot etc. -- I didn't test in natty
I'm confident that some of these have been resolved in natty and I
apologize for not having tested the above with natty.
On a happy note, I found it a real pleasure to use EC2 images; good
