I have attached log files. Here are the details of my setup:
 xen 3.4.1
 dom0: official xen 2.6.18
 domU: fresh install of win2003 ent 32bit sp2 with gplpv_2003x32_0.10.0.138.msi

 a2:~# xm create win2-hvm
 Using config file "/etc/xen/win2-hvm".
 Started domain win2 (id=140)
 a2:~# xentop -d1
 a2:~# xm save win2 win2.save
 a2:~# xm restore win2.save
 Error: /usr/lib64/xen/bin/xc_restore 4 142 2 3 1 1 1 failed
 Usage: xm restore <CheckpointFile> [-p]

 Restore a domain from a saved state.
   -p, --paused                   Do not unpause domain after restoring it

 a2:~#

Let me know if you need more information or have something else for me to test.
