Kernel parameters would get added into sysctl.conf.

The kind of things you can configure in the domain config file are analogous 
to those options you'd put in grub.conf/menu.lst - they don't affect what's 
in sysctl.conf.

You can either:
a) just change sysctl.conf to make the settings you want, as you would for 
a "real" system
b) add parameters to the extra= variable in the domain config file so that 
those parameters are always passed to the domain in boot
c) use pygrub to start the domain, and put the parameters in your domain's 
grub.conf/menu.lst just like you would on a real system.

Cheers,
Mark
