-Subject: [PATCH] Revert "KVM: VMX: enable nested virtualization by default"
-
-This reverts commit 1e58e5e59148916fa43444a406335a990783fb78
-
-As we're not yet there, and this effectively breaks live migration
-for all VMs using host or +vmx which did not manually enabled nesting
-
-Those which already enabled nesting manually have already breakage,
-but that was something to expect. The situation will get better in
-the future (probably post qemu 4.1).
