Private memory for KVM guests

Shuah Khan
 

All,

Sharing an article that describes the in progress kernel work
to support Private memory for KVM guests.

Currently host system has full access to guest memory. This
feature allows guest to map memory as private and this memory
will not be visible to the host.

Thanks so much Shuah for sharing, this private memory helps with our federated learning workload, we will investigate this private memory approach and compare it with the encryption on memory approach (SGX etc)
