From 6b2341eeea43c00b8e266026cec84d57af1484dc Mon Sep 17 00:00:00 2001 From: Liran Alon Date: Wed, 19 Jun 2019 19:21:31 +0300 Subject: [PATCH] target/i386: kvm: Delete VMX migration blocker on vCPU init failure Commit d98f26073beb ("target/i386: kvm: add VMX migration blocker") added migration blocker for vCPU exposed with Intel VMX because QEMU doesn't yet contain code to support migration of nested virtualization workloads. However, that commit missed adding deletion of the migration blocker in case init of vCPU failed. Similar to invtsc_mig_blocker. This commit fix that issue.
