I am having issues getting the serial port to show up. I have xencons=off I have tried com1=auto,8n1,0x03E8,4 and various other formats in my grub.conf and can''t get the port to show up under xen in iether the main domain or virtual domains. -- Richard Thomas - CEO Cyberlot Technologies Group Inc. 507.398.4124 - Voice _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

In one, someone suggested that the only way to get access to the serial port is to use the xen0 and xenU kernels. You''ll then be able to enable the serial port for dom0, and turn it off for domU. This worked for one guy, but hasn''t for me - my serial port is still toast. It might work for you, so try it out.

First, to make grub use the serial console, I add: serial --unit=0 --speed=9600 terminal --timeout=2 serial console to my grub config (grub.conf or menu.lst) then I make a grub section to boot xen and my dom0 like this: title xen-3.0.2-2/2.6.16-xen0 root (hd0,0) kernel /boot/xen.gz com1=9600,8n1 dom0_mem=256000 module /boot/vmlinuz-2.6.16-xen0 console=/dev/ttyS0\ root=/dev/md0 ro qla2xxx boot I compiled the dom0 kernel with the serial drivers disabled (the xen compiliation foo does it for you... just don''t re-enable them.) then I uncomment the line in /etc/inittab that looks like this: T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100 and from the box I''m using to console in (my console server is a FreeBSD box with an 8-port rocketport but a laptop with a crossover cable would work fine as well) I use cu -lttyR02 -s9600 (where ttyR02 is the serial port on the terminal server or laptop) On Mon, 28 Aug 2006, Kanwar Ranbir Sandhu wrote:> On Mon, 2006-28-08 at 17:26 -0500, Richard Thomas wrote: >> I am having issues getting the serial port to show up.

I don''t want to console into the port, I have data i need to gather from the port within a dom Luke Crawford wrote:> > First, to make grub use the serial console, I add: > serial --unit=0 --speed=9600 > terminal --timeout=2 serial console > > to my grub config (grub.conf or menu.lst) > > then I make a grub section to boot xen and my dom0 like this: > > title xen-3.0.2-2/2.6.16-xen0 > root (hd0,0) > kernel /boot/xen.gz com1=9600,8n1 dom0_mem=256000 > module /boot/vmlinuz-2.6.16-xen0 console=/dev/ttyS0\ > root=/dev/md0 ro qla2xxx > boot > > I compiled the dom0 kernel with the serial drivers disabled (the xen > compiliation foo does it for you... just don''t re-enable them.) > > then I uncomment the line in /etc/inittab that looks like this: > T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100 > > > and from the box I''m using to console in (my console server is a FreeBSD > box with an 8-port rocketport but a laptop with a crossover cable would > work fine as well) I use cu -lttyR02 -s9600 (where ttyR02 is the > serial port on the terminal server or laptop) > > On Mon, 28 Aug 2006, Kanwar Ranbir Sandhu wrote: >> On Mon, 2006-28-08 at 17:26 -0500, Richard Thomas wrote: >>> I am having issues getting the serial port to show up.
