VM with interrupt based APF enabled fails to migrate: qemu-system-x86_64: error: failed to set MSR 0x4b564d02 to 0xf3 We have two issues: 1) There is a typo in kvm_put_msrs() and we write async_pf_int_msr to MSR_KVM_ASYNC_PF_EN (instead of MSR_KVM_ASYNC_PF_INT) 2) We restore MSR_KVM_ASYNC_PF_EN before MSR_KVM_ASYNC_PF_INT is set and this violates the check in KVM. Re-order MSR_KVM_ASYNC_PF_EN/MSR_KVM_ASYNC_PF_INT setting (and kvm_get_msrs() for consistency) and fix the typo.
