[Xen-devel] [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. -dulloor Signed-off-by : Dulloor <dulloor@gmail.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

RE: [Xen-devel] [XEN][vNUMA][PATCH 9/9] Disable Migration with numa_strategy
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?> -----Original Message----- > From: Dulloor [mailto:dulloor@gmail.com] > Sent: Friday, July 02, 2010 5:56 PM > To: xen-devel@lists.xensource.com > Subject: [Xen-devel] [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.

I added support only for xl and couldn''t find a place where disable_migrate is referred to in libxl.> > Can you provide more information, please?> >> -----Original Message----- >> From: Dulloor [mailto:dulloor@gmail.com] >> Sent: Friday, July 02, 2010 5:56 PM >> To: xen-devel@lists.xensource.com >> Subject: [Xen-devel] [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.
