From 81f76adad560dfc39cb9625cf1e00a7e2b7b88df Mon Sep 17 00:00:00 2001 From: Maxim Levitsky Date: Thu, 7 Jan 2021 11:38:52 +0200 Subject: KVM: nSVM: correctly restore nested_run_pending on migration The code to store it on the migration exists, but no code was restoring it. One of the side effects of fixing this is that L1->L2 injected events are no longer lost when migration happens with nested run pending.
