Re: [PATCH 1/2] linux-yocto: added kernel configuration for KVM

[Raymond Danks <ray.danks@se-eng.com>]

I'm going to show my lack of knowledge in this area, but I know this is 
going to come up when I push a xen.cfg that I apparently never added.

Is it possible to do something along the lines of PACKAGE_CONFIG in the 
linux-yocto.bbappend?  For example, in the libvirt package one can use 
PACKAGE_CONFIG to construct a "minimal" build of libvirt.  What would be 
the method for one to do the same in this package?

Yes, I imagine that worst case there can be a SRC_URI_distro definition 
that includes only the .scc files required for that "minimal" image 
build, but it seems like we want to keep away from that as much as 
possible being that this isn't a distro layer.

Thanks,
Ray
