+### hvix64.exe (Intel)
+
+hvix64.exe is the intel version of hyper-v. This module along with hvax64.exe does not have any symbols. To find the vmexit handler I simply signature scanned for `0F 78` (vmread instruction)
+and then xreferenced the functions that contained this instruction to see if they were called from a stub of code that pushes all registers including xmm's. It took me a little to find the correct
+function but once I found the stub (vmexit handler) and c/c++ vmexit handler I was able to make a good enough signature to find the vmexit handler on all of the other Intel
+versions of hyper-v.
