From 18ab37ba1cee290923240744288dbee8be9355fb Mon Sep 17 00:00:00 2001 From: Liran Alon Date: Wed, 19 Jun 2019 19:21:35 +0300 Subject: target/i386: kvm: Block migration for vCPUs exposed with nested virtualization Commit d98f26073beb ("target/i386: kvm: add VMX migration blocker") added a migration blocker for vCPU exposed with Intel VMX. However, migration should also be blocked for vCPU exposed with AMD SVM. Both cases should be blocked because QEMU should extract additional vCPU state from KVM that should be migrated as part of vCPU VMState. E.g. Whether vCPU is running in guest-mode or host-mode.
