There never was a kernel that was "optimized" for virtual machines. Merely a few
drivers (boot essential PV drivers) where built-in. By now the generic kernel
covers all that. The other difference was that the virtual image contained fewer
modules. This is now done by having linux-image and linux-image extra. You will
get the right packages by installing the relevant meta-package.

Either "linux-virtual" (which includes the headers) or "linux-image-virtual" (no
headers). If you base your guest installation on the Ubuntu cloud-images you get
that setup directly. Otherwise you had to do a normal install and then install
the virtual meta package and remove linux-generic/linux-image-generic.

But only if you worry about the disk space. Otherwise there is no difference.
