Is there one place (or a small number of places) where some Xen-specific code could be added to Linux to disable the 8250 (using "if (running_on_xen)" without CONFIG_SERIAL_8250=n? It would be nice to retain transparent paravirtualization if possible. Also, will this eliminate the need to have CONFIG_VT=y on dom0 and CONFIG_VT=n on domU?

Thanks, Dan

I went ahead and added polling support to the ns16550 driver and sent it out to xen-devel this morning:

http://lists.xensource.com/archives/html/xen-devel/2005-11/msg 01041.html

With that, the patch below, and disabling CONFIG_SERIAL_8250 in the xen0 config file I have a working serial console and can switch between the xen and dom0 consoles. I'm sending this out now in case anyone wants to have their console work better in the interim (I don't necessarily expect Dan to pick up the ns16550 changes until they're merged upstream). Thanks,

Alex
