Actually, the three Linux distributions that I deal with on a regular basis - CentOS 5, OpenSuSE 10.3/11.1, and SLES10 - do have -xen kernels included on the CD/DVD distribution media. Now, it still takes a little bit of work to get that kernel to boot correctly for a PV domU installation, but it does work. The virt-install graphical management tool will look for the -xen kernel RPM on install media like CD/DVD and extract and boot it in order to kick off the install. If you're using the command line, though, you'll have to accomplish this by hand.

Short answer: No.
- yes, if it's a HVM domU
- mostly no, if you use PV domU. This is mainly because
--> the Linux installer that I know of is having problems mapping the
ISO as cdrom device.
--> Linux install/live CD/DVD usually don't have -xen kernel.
So it's installer and packaging issue. This might change in the future though.
Note that Opensolaris can use CD/DVD for installation for both HVM and
PV domU installation.

In terms of PV domU installation, these tools (xen-create-image,
debootstrap, etc.) act as replacement for standard installation

Depends on your needs and preference. For RHEL-based distros, the
recommended way is to use virt-install using http mirror. For
Debian/Ubuntu-based, I prefer to use debootstrap plus manual
