OK, it seems that since VB 1.6 it is possible in the advanced option to set the PAE/NX support. When checked, it is possible to boot Ubuntu server. Though 2 remarks: * My VM had only 256MB set, so PAE is not necessary (it's for 4GB+ dynamic memory)! * The message reported by the kernel is only interesting to kernel developer, but of no use even for advanced Linux user (I have more than 10 years experience with Linux), see below: The kernel requires the following features not present on the CPU 0:6 Unable to boot - please use a kernel appropriate for your CPU
