- 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).
