We need to migrate PR KVM during transaction and userspace will use kvmppc_get_one_reg_pr()/kvmppc_set_one_reg_pr() APIs to get/set transaction checkpoint state. This patch adds support for that. So far, QEMU on PR KVM doesn't fully function for migration but the savevm/loadvm can be done against a RHEL72 guest. During savevm/ loadvm procedure, the kvm ioctls will be invoked as well. Test has been performed to savevm/loadvm for a guest running a HTM test program: https://github.com/justdoitqd/publicFiles/blob/master/test-tm-mig.c Signed-off-by: Simon Guo <wei.guo.simon@gmail.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org> |
