Save/restore is not a frequently tested feature, but it shouldn't be *this* broken.  I know I've tested it with 5.4 vintage packages, and it was at least working for basic cases.  I'm setting the flags to 5.5, although my guess is that this is either a configuration issue or a hardware-specific issue.

I couldn't found xen3.0.3-96 package. So I repeat the experiments on xen-3.0.3-80 and xen-3.0.3-120. 

1)xen-3.0.3-80, kernel-xen-2.6.18-164.el5 or kernel-xen-2.6.18-172
RHEL5 HVM guests and PV 64bit guest works fine.
RHEL4 PV 32bit guest and RHEL5 PV 32bit guest cann't be save and restored and turn into suspend state.
RHEL4 HVM guests sometimes crash and reboot, sometimes works fine, sometimes crash and turn into zombie guest.

2)xen-3.0.3-120, kernel-xen-2.6.18-238.el5
all guests works well after single/multi save/restore in sufficient or insufficient space.
But sometime zombie guests may show up after destroying the save-failed PV guests(reported in Bug #673456).
