Looks like a bigger problem. Could you post your Xen version number and the domU configuration file please?

PS: I'm always getting two equivalent mails from you?!! Please just do a "Reply to all", meaning you send exactly one mail to me with "xen-users@xxxxxxxxxxxxxxxxxxx" as CC.

Hi Andreas, and everyone,

I did as you said and I set extra= "xencons=tty". Now the boot precess goes some more lines further but now there is another problem. These are the last lines of the output of xm create -c ...

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)
chvt: can't open console
chvt: VT_ACTIVATE: Bad file descriptor
ALERT! /dev/sda1 does not exist. Dropping to a shell!


BusyBox v1.10.2 (Ubuntu 1:1.10.2-1ubuntu7) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs) 

Does that mean that the virtual machine cannot recognize the file system? I have a SATA hard drive and I am using the same kernel and setup as for dom0. I tried also specifying the root device as its UUID but didn't work neither.
Do have any idea?

Thank you

Check if "xm list" shows you a running state ("r" for running or "b" for 
booting, "p" often means that an error occurred). I guess you might have 
forgotten the line

extra = ''xencons=tty"

so the domU seems to hang because it doesn't show the login prompt on 
the correct console.

Compare to this thread:

Hi,

I am having troubles starting a domU. I run it with: xm create -c config_file. Then I can see the output and it seems as if everything is going well. Then, the output suddenly stops without any failures and there is nothing I can do. The cursor is blinking but not responding to any keyboard inputs. I even cannot kill the process with ctrl+c. When I run xen-list-images it shows the image: 
$ xen-list-images
Name: virtualrouter1
Memory: 128
IP: 10.23.100.13

Here is the output of xm create:
