I realized this is probably better suited for the devel list.. basically,
is there any way in the BOCHS bios to enable ''Serial Console
Redirection'',
where you see the BIOS contents over the serial line?
Windows 2003''s ''Emergency Management Services''
console (which allows you
to do installs and fix stuff over the serial line) requires this to
activate.. piece of crap.
It''d also be nice for *NIX installs on HVM, where you don''t
want to deal
with SDL or VNC.
Thanks much! :)

Subject: [Xen-users] HVM: Emergency Management Services for W2K3 under Xen
HVM?
It''d be nice to be able to use the "Emergency Management
Services" for Windows
2003 under Xen.. apparently, to use them, however, the BIOS has to support
serial redirection. Is there any way to get the BOCHS bios to support serial
redirection? I haven''t been able to find anything.
Thanks!

Re: [Xen-devel] HVM - BIOS serial console redirection?
Have you tried serial = ''pty'' in the domU''s configuration? This makes the domU''s virtual serial port look like the console of a paravirtualized domU, so you can use ''xm console'' and ''xm create -c'' on it. I''m not sure what you mean by the BIOS contents ... Good luck.

If the BIOS doesn''t support console redirection then you can turn the SAC/EMS on with bootcfg.exe. We''ve done that but it still doesn''t work. We''ve been using serial=''pty'' all along. However looking at the serial port configuration in the hardware manager I can see that the serial port doesn''t seem to be working (the usual windows exclamation mark). It claims a conflict in the IO range from 0x3F8 to 0x3FE with the "Standard PC" device which seems to be a place holder for the HAL. I guess if we could fix that out it would work, but we haven''t figured it out yet... I could manually set the port to the COM2 IO/IRQ range which appear to be free. -- Nick Craig-Wood <nick@craig-wood.com> -- http://www.craig-wood.com/nick _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
