Though the code compiles with a big endian toolchain, the kvm-unit-tests do not work at all in big endian mode on ARM. Until someone steps up to fix this, disable the package completely on big endian ARM targets.

kvm-unit-tests is a project as old as KVM. As its name
|
|
suggests, it's purpose is to provide unit tests for KVM. The
|
|
unit tests are tiny guest operating systems that generally
|
|
execute only tens of lines of C and assembler test code in
|
|
order to obtain its PASS/FAIL result. Unit tests provide KVM
|
|
and virt hardware functional testing by targeting the
|
|
features through minimal implementations of their use per
|
|
the hardware specification. The simplicity of unit tests
|
|
make them easy to verify they are correct, easy to maintain,
|
|
and easy to use in timing measurements. Unit tests are also
|
|
often used for quick and dirty bug reproducers. The
|
|
reproducers may then be kept as regression tests. It's
|
|
strongly encouraged that patches implementing new KVM
|
|
features are submitted with accompanying unit tests.
