Hi guys. I cannot wrap my hear around this: -> $ unset _Val; test -z ${_Val}; echo $? 0 -> $ unset _Val; test -n ${_Val}; echo $? 0 -> $ _Val=some; test -n ${_Val}; echo $? 0 What is this!? How should two different, opposite tests give the same result Is there some bash option which affects that and if so, then what would be the purpose of such nons...

Changes from v2 to v3: - Use pfn_to_paddr() to get the address from frame number instead of doing shift directly. - Remove some unnecessary initialization code and add "static" to vmentry_fields and gpdptr_fields. - Enable the VMREAD/VMWRITE bitmap only if nested hvm is enabled. - Use clear_page() to set all 0 to the page instead of memset(). - Use domheap to allocate the
