Re: [Xen-devel] Requesting for freeze exception for RMRR

Please work with maintainers to get those hvmloader patches acked or

I will do.

Note Jackson and Campbell also raised some comments to improve current

2. explain why it needs to be in this release (benefits).

RMRR mechanism was broken for a long time and this makes VM always face
security issues. In addition, those associated devices can't be passed
through to VM and even result in VM crashes.

3. explain why it doesn't break things (risks).

Our policy makes sure that system will work in the original way by default
as without the RMRR patches. And especially, this series just impacts those
platforms which have RMRR.

Your patches touch crucial path in hvmloader to build memory map. There
is risk that it may break hvmloader even if it is turned off.

I would need at least some positive test results from you to confirm if
this feature is turned off everything works as before.

Could you show what sort of test you need here? I just did boot a VM without any RDM parameters. I just think maybe someone had this good experience to check this.
