And is your Xen precisely matched against libxc? I fixed XENMEM_maximum_gpfn
to really return the last gpfn known to the guest, rather than the last plus
one. Hence we now add one to that value to get p2m_size in xc_domain_save().
But if this fixed xc_domain_save() was run against older Xen, you would have
p2m_size too big by one.
