Hide Forgot
With the F-9 pv_ops kernel-xen builds, we have to add "console=hvc" to the kernel command line in order to get output on the Xen console. We didn't need to do "console=xvc" before pv_ops, so we need to figure out how to get back to that nicer situation.

Thanks Markus, this in rawhide kernel-xen
Okay, I've dropped this patch again in kernel-xen-2.6-2.6.25-0.12.rc7.git6.fc9 at Markus's request See bug #437706 for more details
Markus has a good summary of the issue here: http://lkml.org/lkml/2008/4/2/209
Markus just sent this patch upstream: http://lkml.org/lkml/2008/4/4/239 Assuming it builds, it'll be in kernel-xen-2.6-2.6.25-0.16.rc8.fc9
Okay, with pvfb configured, you don't seem to be able to force hvc to be the preferred console using "console=hvc" This is with kernel-xen-2.6-2.6.25-0.19.rc8.fc9 on both i686 and x86_64
Next try: http://lkml.org/lkml/2008/4/10/209
kernel-xen-2.6.25-0.22.rc9.fc9 includes Markus's latest patch and seems to fix the "can't override pvfb tty console with console=hvc" This build, or a later one, should be tagged for F-9 before GA
