KVM: SVM: Add support for KVM_SEV_RECEIVE_START command

2021-04-21T16:20:04+00:00

The command is used to create the encryption context for an incoming
SEV guest. The encryption context can be later used by the hypervisor
to import the incoming data into the SEV guest memory space.

KVM: SVM: Add support for KVM_SEV_SEND_CANCEL command

2021-04-21T16:20:04+00:00

After completion of SEND_START, but before SEND_FINISH, the source VMM can
issue the SEND_CANCEL command to stop a migration. This is necessary so
that a cancelled migration can restart with a new target later.
