Xen devel - Jul 2010 - [XEN][vNUMA][PATCH 9/9] Disable Migration with numa_strategy

We don’t preserve the NUMA properties of the VM across the migration.
Just disable the migration for now. Also, setting disable_migrate
doesn’t seem to stop one from actually migrating a VM. So, this patch
is only for documentation.

Hmmm... disable_migrate did indeed disable migration last
time I checked it.  But to be precise, it disabled restore
and live migration from the receiver side (which should
cause the migration to fail).  I''m also not sure if it
was ever tested for HVM.  And I implemented it in xend
not xl, so perhaps that is what is different?

Can you provide more information, please?

Oh ok .. I added support only for xl and couldn''t find a place where
disable_migrate
is referred to in libxl.
