arm/arm64 supports running tests under kvmtool, but kvmtool's syntax for
running and configuring a virtual machine is different to qemu. To run
tests using the automated test infrastructure, add a new test parameter,
'kvmtool_params'. The parameter serves the exact purpose as 'qemu_params',
but using kvmtool's syntax.
