Thank you.  I'm not sure how I missed this.  It was even discussed on
this list back in July:
http://lists.xensource.com/archives/html/xen-users/2009-07/msg00333.html

I read on the Xen Wiki
(http://wiki.xensource.com/xenwiki/XenDom0Kernels) that future Xen
versions (3.5/4.0) will default to the pv_ops dom0 kernel.  As most of
the Nvidia drivers are distributed in binary format, does this mean that
Nvidia would have to modify their driver code (aka specifically support
Xen pv_ops dom0) for this to work with future Xen versions?  In this
case it probably wouldn't be wise for me to go down the binary drivers
path and should either try something else or settle on nv.

Does anyone know how long the "old-style" dom0 kernel will be
supported?  Will Xen 3.5/4.0 support both, with pv-ops as the default,
or is the idea to eventually drop the old-style kernel.  As a noob to
Xen, what is the significance of kernel version 2.6.18?  Did something
in the kernel change that doesn't allow for an older style dom0 kernels,
or is it just more effort then its worth to branch the newer releases
(especially with all the pv_ops success).

Brandon
