I have been trying to use kvm to do some microcontroller programming,
mostly with success - until I want to send an ascii NULL down the port.
(I don't know what's going on there, but if you have any ideas, that
would be
fantastic)Our communication protocol is very touchy about speeds, so the
baud rate was being passed on correctly when I used qemu/kvm like this:
kvm <irrelevant options> -serial /dev/ttyUSB0
(I'm using a usb-serial converter). You can have up to 4 COM ports by
repeating
the -serial "device" option. See the qemu man page for more details
(yes, it works
just the same when you're invoking it with kvm).
If you're trying to use virt-manager, then don't.
Virt-manager stops you from having access to a bunch of the underlying
features
of kvm/qemu such as serial ports. I'm told they're working on it, but
it's only useful
for a basic setup at the moment.

First of all, is this the mailinglist to ask this question? Or should I
ask it on the qemu lists?
I'd like to run WinXP/ Vista within kvm and do microcontroller
programming. My host is linux of course. I had some success using the
qemu pre 0.8 way using slsnif. Setting baud rate to 115200 made some of
the operations work, but most don't.
So is there a way to connect COM1 within the guest to /dev/ttyS0 so that
baud rate settings within the guest will be forwarded to /dev/ttyS0 on
the host?
check out for qemu's "-serial" option
