Following is a workable grub config to enable serial out input, but the kernel will be UP.

I've had this working fine on previous releases from SuSE and others and on the current hardware.<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> When happens at the moment is that the machine boots, gives me the grub menu, where I can choose my boot system (so it's hearing my keystrokes) but once it proceeds into the Xen and ultimately Linux, it doesn't want to hear keystrokes from me any more: I can't CTRL-A (x3) and get the Xen console, nor the linux console which is configured in /etc/inittab. I see the boot messages go past and get a login prompt, but no keystrokes get through or can control the machine.<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> It's making it tricky to send the box to co-lo as I can't get serial control if I take down the network, or Hypervisor control to reboot Dom0.<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> My rpms are:<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> kernel-xen0-2.6.16-1.2080_FC5<o:p></o:p> </div> <div> xen-3.0.1-4<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> and my grub.conf is:<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> default=0<o:p></o:p> </div> <div> timeout=5<o:p></o:p> </div> <div> #splashimage=(hd0,0)/grub/splash.xpm.gz<o:p></o:p> </div> <div> #hiddenmenu<o:p></o:p> </div> <div> #<o:p></o:p> </div> <div> serial --unit=1 --speed=9600 --word=8 --parity=no --stop=1<o:p></o:p> </div> <div> terminal --timeout=10 serial console<o:p></o:p> </div> <div> #<o:p></o:p> </div> <div> title Fedora Core (2.6.16-1.2080_FC5xen0)<o:p></o:p> </div> <div> root (hd0,0)<o:p></o:p> </div> <div> kernel /xen.gz-2.6.16-1.2080_FC5 dom0_mem=384000 com2=9600,8n1 console=com2,vga sync_console <o:p></o:p> </div> <div> module /vmlinuz-2.6.16-1.2080_FC5xen0 ro root=/dev/VolGroup00/LogVol00 rhgb selinux=0<o:p></o:p> </div> <div> module /initrd-2.6.16-1.2080_FC5xen0.img<o:p></o:p> </div> <div> <o:p> </o:p> </div> I'd appreciate any guidance on silly things I may have done here; I'm banging my head on this one.<o:p></o:p> <div> <o:p> </o:p> </div> <div> Many thanks,<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> Tony<o:p></o:p> </div> <div> <o:p> </o:p> </div> <div> <o:p> </o:p> <div> <div> tony <st1:place w:st="on">clark</st1:place><o:p></o:p> </div> <div> director - <a href="mailto:tony.clark@rsp.com.au">tony.clark@rsp.com.au</a><o:p></o:p> </div> <div> --------------------------------------------------------------- <o:p></o:p> </div> <div> rising sun pictures - www.rsp.com.au <o:p></o:p> </div> <div> redefining visual effects delivery <o:p></o:p> </div> <div> ---------------------------------------------------------------<o:p></o:p> </div> <div> address level 1 / 133 gouger street<o:p></o:p> </div> <div> <st1:City w:st="on">adelaide</st1:City> <st1:State w:st="on"><st1:place w:st="on">south australia</st1:place></st1:State> 5000<o:p></o:p> </div> <div> --------------------------------------------------------------- <o:p></o:p> </div> <div> <st1:City w:st="on"><st1:place w:st="on">adelaide</st1:place></st1:City> ph +61 8 8400 6400 fax +61 8 8400 6401 <o:p></o:p> </div> <div> <st1:City w:st="on"><st1:place w:st="on">sydney</st1:place></st1:City> ph +61 2 9338 6400 fax +61 2 9338 6401<o:p></o:p> </div> <div> --------------------------------------------------------------- <o:p></o:p> </div> <div> rising sun research - <a href="http://research.rsp.com.au">http://research.rsp.com.au</a> <o:p></o:p> </div> <div> ---------------------------------------------------------------<o:p></o:p> </div> <div> <o:p> </o:p> </div> <o:p></o:p> </div> <o:p> </o:p> </div> </div> </div> </body> </html>
