[Qemu-discuss] Q: nested virtualization and VMX live migration

[Syrone Wong]

Hi all,

The VMX live migration blocker is added via
https://github.com/qemu/qemu/commit/d98f26073bebddcd3da0ba1b86c3a34e840c0fb8,
it claims "Nested VMX does not support live migration yet".

While a commit from Linux 4.20 states
> With live migration support and finally a good solution for exception event 
> injection,
> nested VMX should be ready for having a stable userspace ABI.

and the nested virtualization is enabled by default. Should we remove
the blocker for Linux 4.20 and upper?
