... and here's the first mistake. I assume you're converting an
existing linux installation to Xen?
I highly suggest NOT to do so on your first domU/guest.

This is the first mistake.
While domU can use kernel located in dom0, if you choose to do so then
you also need to specify the additional kernel arguments needed (e.g.
"root=/dev/xvda1"). It should be on an "extra" line.
Also, you need to have a matching set of modules in domU's
/lib/modules (although this does not directly related to the error
you're having now).

this one should be xvda instead of sda

... and you need to match "root=..." kernel arg to whatever's detected
here. Since you use sda on the config file, F14's kernel will actually
detect the disk as xvde, which can be confusing. Better stick with
xvda.

The best way for beginners is start with the easy things first.
Install virt-manager, install a new domU, look at the generated config
file and disk image, then start changing things from there.
