1 LTP KVM Test API
4 Testing KVM is more complex than other Linux features. Some KVM bugs allow
7 system. The worst types of KVM bugs may even allow the guest code to crash or
8 compromise the physical host. KVM tests therefore need to be split into two
9 components – a KVM controller program running on the physical host and a guest
18 1. Basic KVM test structure
21 KVM tests are simple C source files containing both the KVM controller code
24 once to compile the KVM controller part and embed the payload binary inside.

29 A KVM test source should start with `#include "kvm_test.h"` instead of the
34 LTP headers are not available in the payload compilation pass, only the KVM

64 The KVM controller code is a normal LTP test and needs to define an instance
66 functions. Basic implementation of all three functions is provided by the KVM
71 library functions, etc. except for the small subset provided by the KVM guest
