Subject: xl/xm save -c fails - set_vcpucontext EOPNOTSUPP (was Re: xl save -c issues with Windows 7 Ultimate)

I was testing xl/xm checkpoint with the latest c/s in the repo, 23300.
neither xl nor xm seem to work. The error code is 95 (EOPNOTSUPP).
Migration works but not checkpointing. While doing a xc_domain_resume,
the "modify_returncode" phase (for suspend_cancel) fails. Tracing through
the control flow, I found that the hypercall for set_vcpucontext
(in do_xen_hypercall() from xc_private.c) fails with this error code.
I have tested this with a 64-bit 2.6.39 and 32-bit 2.6.18 pv domU.
Any help would be great.
