[Part2 PATCH v4 24/29] KVM: SVM: Pin guest memory when SEV is active

The SEV memory encryption engine uses a tweak such that two identical plaintext pages at different location will have different ciphertexts. So swapping or moving ciphertexts of two pages will not result in plaintexts being swapped. Relocating (or migrating) physical backing pages for a SEV guest

[Part2 PATCH v4 27/29] KVM: SVM: Do not install #UD intercept when SEV is enabled

On #UD, x86_emulate_instruction() fetches the data from guest memory and decodes the instruction bytes to assist further. When SEV is enabled, the instruction bytes will be encrypted using the guest-specific key and the hypervisor will no longer able to fetch the instruction bytes to assist UD
