Hello,
   Thanks.
        
  1) I am working on 32 bit x86.
        
        2) I triled  with the default, unchnaged xend-config.sxp (taken from
        /dist/install/etc/xebn)
        I ran:
        tail -f /var/log/xend.log
        xm migrate myDomU 127.0.0.1
        
        
        
        I want to add something:
        I think my memory division for domo and domU is OK,
        but I am not sure:
        This was done on a machine with RAM 128 MB.
        in grub.conf I have this allocation:
           kernel /boot/xen.gz dom0_mem=60000
        and in myDomU config file I have mempry set to 32 MB thus:
        
        kernel ="/boot/vmlinuz-2.6.12.6-xen0"
  memory = 32
  name = "myDomU"
  nics = 1
  disk = ['file:/work/dev/tests/feodra_xe_img/fedora.img,sda1,w']
  root = "/dev/sda1"

        
This is the log I got: (seems to be a problem with restore:
        I see "Failed to increase reservation" and other error messages)
