[Xen-users] No login prompt for DomainU with Xen 3.1 on CentOS 5.3

[W.Guo1@xxxxxxxxxxxxxx]

Hello Dear everybody!

I just installed CentOS 5.3 and try the built-in Xen 3.1 with it. But even the
typical ttyLinux doesn't work when the domain is created.-- it just doesn't give
me the login prompt while the domain ttylinux is booted. 



[root@soe-hd513-pc102 nimbus]# xm create ttylinux-xen.conf -c

Apparently the original configuration file for ttylinux image needs to be
adapted. My configuration file ttylinux-xen.conf is like this:
------------------
kernel = "/boot/vmlinuz-2.6.18-128.2.1.el5xen"
ramdisk = "/boot/initrd-2.6.18-128.2.1.el5xen.img"  ### I must have the ramdisk
option.
memory = 64
name = "ttylinux"
vif = ['']
ip = "192.168.1.3"
disk = ['tap:aio:/home/wei/work/nimbus/ttylinux-xen,sda1,w']  ### file: also
works.
root = "/dev/sda1 ro"
extra = "3 xencons=console"   ### This option works in Xen 3.2 on Ubuntu 8.04.
-------------------

If I remove the extra option, or try to use 
extra = "3 xencons=tty" or extra ="3 xencons=tty console=tty0"
no good either.

I tried other images than the typical ttylinux, and got the same problem.

I digged into the Xen maillist archive and tried to find some solution who had
the same problem. Somebody suggested to modify the image file by changing
/etc/inittab and the questioner said it worked. But I don't want to change image
yet because the image was working when I tried it on Ubuntu with Xen 3.2. 

Actually I think Xen 3.1 should work perfectly with a fresh installed CentOS.

Could anybody please help?

Thank you in advance!

Wei
