Hi, Pasi:
Thanks for the reply. I have tried the configuration file there.
OS is Ubuntu 10.04, Xen is compiled from source, 4.0
kernel is using jeremy git, branch changed to 2.6.32.x
configured to using serial port to show the debug info, it says:
Built 1 zonelists in Zone order, mobility grouping on. Total pages: 481039

at the same time, the target machine would stop at

Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
-check rootdelay= (did the system wait long enough?)
-check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! does not exist. Dropping to a shell!

Have you encountered this before?
Thanks very much!
Best!
