[Fedora-xen] RE: How to make xen0 and xen with http://free.linux.hp.com/~agriffis/fedora-kernel-rpm

[Zhang, Xiantao]

Aron,
	Seems we have two method, maybe we can use xen-unstable.hg to generate xenlinux patch as first choice or talk to redhat side and persuade them pulling CSet from xen-unstable.hg just at it syncing with xen-ia64-unstable.hg. If so, it will reduce unnecessary extra work more :) 
Just FYI.
Thanks & Best Regards
