[Xen-devel] Re: cpuid information to hvm guest

[Keir Fraser <keir.fraser@xxxxxxxxxxxxx>]

Hiding those details by default is a good strategy we’d like to maintain. Furthermore we cannot change CPU-to-LAPIC identifier mapping without breaking saved guest images, which is not acceptable. If our hiding of host information is broken, we’d like a patch to fix it; likewise any other CPUID inconsistency. What specific issues are you seeing?
