Just something to be added: - This procedure doesn''t work with a Fedora 9 DomU - Maybe you have to blacklist some modules in the Dom0: AFAIK you have to rmmod (better: blacklist on boot using modprobe.conf) these modules: serial_core 8250 and 8250_pnp ----- Ursprüngliche Mail ---- Von: Federico Fanton <fake@panizzolo.it> An: xen-users@lists.xensource.com Gesendet: Freitag, den 17.

I just wanted to share all the bits of information I needed while trying to get a serial modem to work under a Xen guest :) I found other howtos but every one was missing something. So, my setup consists of dom0 and domU with CentOS 5.2, kernel 2.6.18-92.1.10.el5xen and Xen 3.2.1 To get /dev/ttyS0 to work under domU: - Tell Xen to use something else for its console: in /boot/grub/menu.lst, add "console=xvc0 xencons=xvc0" to the kernel parameters (maybe just xencons is needed) - Tell Xen to "show" IRQ/port to the domU: in domU''s .cfg add addirq = [ 4 ] ioports = [ "3f8-3ff" ] - Tell the domU to autoload the serial module: create in /etc/sysconfig/modules an executable script containing modprobe 8250 Bye! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users __________________________________________________ Do You Yahoo!?
