I just tried to install rawhide/development to a xen domU with virt-manager,
and it seems current kernel (or xen drivers?) has a bug that prevents
anaconda/installer from autoloading the needed drivers..
[snip]
"No driver found"
"Unable to find any devices of the type needed for this installation type."
"Would you like to manually select your driver or use a driver disk?"
This could either be the xen kernel or the changes within anaconda to
stop using kudzu. Please file it in bugzilla so that it doesn't get
lost in the noise of the list.
xenblk/xennet don't export any aliases that would cause them to get loaded.
So they don't get loaded.
That would do it. Thus, file the bug against kernel-xen. They should
have modaliases so they can get loaded automatically

Implement module autoloading via modalias and udev for xen drivers.
