Xen 4.2 in rawhide

[M A Young]

Xen has been updated to version 4.2.0 in rawhide. To get this to work Cole 
Robinson has disabled libxl support in libvirt because libvirt doesn't yet 
support the 4.2 updates to libxl. There should still be time to get xen 
4.2 into Fedora 18 if there aren't any problems in rawhide.

So, just to be sure I understand this correctly, Fedora rh/18 will have
Xen 4.2 and, if one whats to use it with libvirt, that would happen
through XenD, right?

Just in case you're interested and have not seen that, as a consequence
of your previous message in this list, George and I started an
investigation about integration issues between Xen >=4.2 and libvirt.

Here's the thread:

Yes, libvirt has two drivers (packaged separately in Fedora), xend and 
libxl. libvirt will still be able to use the xend driver in rawhide, but 
the libxl driver is disabled (ie. not built) in libvirt. I expect it would 
be easy to add back in once libvirt understands libxl 4.2 .
