I still struggle a bit to understand what you mean. It's exact
I've looked into those settings and vcpu affinities on Xen wiki page.
However what I'm trying to argue about is memory should be migrated when
vcpus are moved to another node. But setting a vcpu's affinity only seems
to allow vcpu migration between different nodes. As my NUMA server is on
the way
Thank you for such a detailed reply!
Currently what's in my mind is to let memory also be migrated when a vcpu
or a vm has to be migrated to some other node. In that case let's suppose
there would be a simple load balancing mechanism. And I think a NUMA
machine can be some sort of seen as small sym

Status is: it's not there, and won't happen soon. I've started working
on it, but then got preempte

Xen doesn't support memory migration at the moment. However Xen scheduler
won't migrate vcpus o
Let me be more specific, such idea is for the NUMA scheduling as currently
xen only migrate vcpus but leave memory at the previous node.

Hi all,
I'm sorry for taking your time and I'd like to make an enquery about the
status of VM migration support on a NUMA server. Currently It looks like
when a vm is migrated only its vcpus are moved to the other node but not
its memory. So, is anyone trying to fix that issue? If I want to do it
