Hi,
How do i configure a serial console for a f10/x86_64/PV guest to work.
/boot/grub/grub.conf:
...
title Fedora (2.6.27.21-170.2.56.fc10.x86_64)
root (hd0,0)
kernel /vmlinuz-2.6.27.21-170.2.56.fc10.x86_64 ro
root=/dev/rootvg/root_lv rhgb quiet console=ttyS0
initrd /initrd-2.6.27.21-170.2.56.fc10.x86_64.img
...
The above dose not work.

Now, all the above said, on a modern centOS PV guest, I didn''t have to do any of that. /dev/console simply works. [root@nineteen /home/farmers/farmersfresh]# more /proc/cmdline root=/dev/sda1 ro aoe_iflist=eth1 co:12345:respawn:/sbin/agetty 9600 console [root@nineteen /home/farmers/farmersfresh]# ls -l /dev/console crw--w---- 1 root tty 5, 1 Apr 12 09:51 /dev/console Obviously, your mileage may vary :) ... Unless of course you REALLY want to route the console for one specific guest out a physical serial port. I''m not sure how you''d do that. At times the XEN serial console has conflicted with the serial port drivers... I haven''t looked at that for a long time though :( -Tom _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
