Sorry - I thought I had sent my last reply to the list as
well.
Thanks
for the advice, that is exactly what I did, and it worked, in that I could see
and access to serial ports in the Win2k3 domU. Unfortunately, I think
I am going to have to scrap this configuration. I am running Hylafax in
the dom0 and serial port performance under the xen kernel is not
acceptable. I can't even reliable receive one fax at a time let alone have
all 8 ports on the 8 port fax modem active at once. When I boot into the
native kernel, I have no issues at all. I would have expected this
had I been running hylafax in a domU, but not the dom0.
Have
you seen performance issues in regards to serial ports?

You could let
the config file create com1 and let the wrapper script only add
com2.

Since, I have upgraded to xen
3.3.1 from the the gitco repo. I am
still having issues. It
seems that by default qemu-dm will provide
more emulated hardware, like a
serial and parallel port, unless you
tell it not to (serial none).
When I have attempted to configure the
.sxp file with more than one
serial port, the vm won't start. If I
use the wrapper script, then
I get a 'com1' and 'com2' in the device
manager, but com1 doesn't work
and in fact hyperterminal sees two
'com1' ports. I am sure this is
a confusion between the default
serial port provided to the vm and the
serial ports I am trying to
give to it via the wrapper script.
So,
I succeeded in starting a hvm where windows sees two serial ports,
but
one of them doesn't work.

There doesn't appear to be anything more in the logs.
