The effort required is to emulate all the necessary instructions to be able to emulate completely the real mode executions of the popular guests( Linux/window/Solaris..). The problem lies in the tough tests that Intel is doing on vm entry in real mode. Complete real mode emulation must be implemented inside the KVM - at least all the common instructions. It would be superb if you'll take over this. If you do we'll help as much as possible. >Will it do everything right if I just set cr0 to indicate that we're >not executing in 32bit more? The vmx_vcpu_setup starts in real mode - check the end when calling vmx_set_cr0 (checking the CR0_PE_MASK bit). >Will KVM spit out some kind of debug information when it encounters an >instruction it cannot handle ? x86_emulate_memop return -1 on error and 0 on success.
