The fairly "standard" way to identify different hypervisors at a technical level on x86 is to read CPUID leaf 0x40000000. For KVM it reports the string "KVMKVMKVM\0\0\0" while on QEMU >= 2.10 it reports "TCGTCGTCGTCG" for QEMU emulation. In general it is best not to try this yourself and instead just run the "virt-what" command, as there are many other heuristics to check for various hypervisors / architectures.
