Hi, this patch complete the previous one. Hypercalls are only allowed from kernels. I have added an 'unsafe_hypercall' boolean command line option to enable the two debugging hypercalls. This option is disabled by default, as it may be used to write in the kernel area. Tested by boot+shutdown of dom0+domU (option off). Tested by boot of dom0 + postat (option on). Tristan.
