Just a C implem nitpick, but that can lead to interesting debugging sessions (I think I got beaten by that a couple of time). Nowhere the compiler can guess that you're accessing a 2 dimentional array with a row of length domInfo.nrVirtCpu, it's a one dimension array so I think cpuMaps[vcpu][byteCpu] is equivalent to cpuMaps[vcpu + byteCpu] there and unless I misunderstood both case that won't work as expected. This is also why I suggested a macro this can of code is easy to get wrong. Daniel
OK, you are right. ;-) Thanks.
