|

- New 'domid_policy', allowing domain-ids to be randomly chosen.
|
||||
- Option to preserve domain-id across migrate or save+restore.
|
||||
- Support in kdd for initial KD protocol handshake for Win 7, 8 and 10 (64 bit).
|
||||
- Tech preview support for Control-flow Execution Technology, with Xen using
|
||||
Supervisor Shadow Stacks for its own protection.
|
||||
|
||||
### Changed
|
||||
- The CPUID data seen by a guest on boot is now moved in the migration
|
||||
stream. A guest migrating between non-identical hardware will now no
|
||||
longer observe details such as Family/Model/Stepping, Cache, etc changing.
|
||||
An administrator still needs to take care to ensure the features visible to
|
||||
the guest at boot are compatible with anywhere it might migrate.
