[Xen-devel] [PATCH v2 0/4] x86/vvmx: correctly emulate VMREAD and VMWRITE

2017-02-06 Thread Sergey Dyasli
Currently, emulation of vmread and vmwrite for a guest leads to BUG() in cases when actual VMREAD or VMWRITE ends up in VMfail due to invalid arguments. The goal of this patch series is to prevent the BUG() from happening and report any kind of VMfail back to the guest, just like it would be done
