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. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
