VT: serial console?

VT: serial console?

[Gerd Hoffmann]

  Hi,

Current Testing tree: serial ports seem not to work with full
virtualization.

/etc/xen/xmexample.hvm suggests to use "serial='pty'".  That seems to
work partly, at least the pty allocated shows up in xenstore and it is
possible to use "xm console ..." to connect.  But I don't see any serial
console output from the linux kernel (boot with console=ttyS0, fire up a
getty).

Any idea what is going wrong?

cheers,

  Gerd

One more data point: with sdl active it works ok, with vnc it doesn't.

cheers,

Gerd-

I might have done this, which patchset are you using?  I introduced support for the Summagraphics tablet under VNC in patchset 9259 and it used port 0.  With patchset 9967 I woke up and moved the tablet to port 1, freeing /dev/ttyS0 up for the console again.  If you're using a patchset between those two that's probably your problem.

It's 9674 (Testing tree, somewhen last week), so I guess this explains
the problem ;)

Thanks,
