[Xen-devel] make clear a vmexit reason

[YAO <yffbrave@xxxxxxxxx>]

Hi,

Lately I was puzzled by a vmexit reason 31 which was defined asÂEXIT_REASON_MSR_READ

I allocated an array in xen data section and assigned its MFN to an EPT entry of a domainU,Â

I thought the domU could access this array but after that the domainU crashed

and xen gave me this exit reason "Bad vmexit (reason 31)"

But there is nothing to do with MSR READ, so I'm confused...

Can anybody give me a clear explanation?

Regards,

Eric
