1. Strong understanding of virtualization (on Intel64 and IA64) and para-virtualization concepts (Xen. KVM and L4 based solutions (Iguana/L4))
2. Strong knowledge of modern kernels (memory management, process management, kernel ABI, construction) of Linux, BSD family and micro-kernels L4, MINIX
3. Strong understanding of system library structure and internal implementation of System V, POSIX and internals (GNU LibC(libC, libpthreads), Solaris libC, {Net,Free,Net}BSD)
4. Strong knowledge of binary executable and linkage formats (ELF, COFF) including initial kernel loaders and modules loading for Linux, Solaris and BSD family.
5. Strong understanding of binary translation implementations (QUEMU) and emulations of kernel interfaces (QUEMU, Intel IA32EL btlib)
6. Strong understanding of Intel micro-architecture (Intel64, IA64) and optimization methods and techniques used in enabling process.
7. Strong knowledge of debuggers (GDB, CDB, in-kernel Linux, NetBSD, L4, Microsoft Windows) and debugging concepts.
MRTE world:
