Re: [Xen-users] How to use PV on HVM


The crash which I reported is a warning on slow path. I recompiled it again and I was able to boot into the linux-pvhvm kernel. Thanks for all the help.

Thanks & Regards,

That tutorial is old, and the patch referenced there might not be current anymore..
Please see lkml and xen-devel archives for more information about the new
Xen pv-on-hvm drivers that were merged to upstream Linux 2.6.36.

The patch to Xen was submitted together with the drivers, in August 2010 I think..
that blog post is from May.
