Xen users - Jun 2011 - [XCP] Console with PV kernels?

All:

I''m currently using the older Python-based Xen tools on a cluster of
machines, but we''re looking to transition to XCP as the platform of
choice
for our applications. However, I''ve run into one issue that''s
sort of a
blocker: paravirtual Linux domUs boot and run, but the console device is
strangely broken. Most of the output reaches the connected user (some bytes
are dropped), but any input is apparently completely lost. The VMs in
question work perfectly with the older Xen environment, and as I mentioned,
everything else seems to work identically. Is there something I need to do
with XCP (we''re currently testing with a mix of 0.5 and 1.0,
we''ll be moving
totally to 1.0 in the near future, and this happens with both) to make this
work right? A change in the domUs? We''re just using
''console=xvc0'' or
''console=hvc0'' as appropriate, and running a normal getty
against the
console device. Any suggestions would be appreciated, thanks.

Regards,
