The STIBP flag may be supported by the host KVM module, so QEMU
|
|
can allow it to be configured manually, and it can be exposed to
|
|
guests when using "-cpu host".
|
|
|
|
No additional migration code is required because the whole
|
|
contents of spec_ctrl is already migrated in the "cpu/spec_ctrl"
|
|
section.
|
|
|
|
Corresponding KVM patch was submitted at:
