конечно понятно, как и то что эта опция отношения к x64 в гостевой системе не имеет никакого.
Я потратил время, но нашел в документации к virtualbox
Even though VirtualBox does not always require hardware virtualization, enabling it is required in the following scenarios:
Certain rare guest operating systems like OS/2 make use of very esoteric processor instructions that are not supported with our software virtualization. For virtual machines that are configured to contain such an operating system, hardware virtualization is enabled automatically.
VirtualBox's 64-bit guest support (added with version 2.0) and multiprocessing (SMP, added with version 3.0) both require hardware virtualization to be enabled. (This is not much of a limitation since the vast majority of today's 64-bit and multicore CPUs ship with hardware virtualization anyway; the exceptions to this rule are e.g. older Intel Celeron and AMD Opteron CPUs.)
Так что вы до сих пор будете настаивать что
" эта опция отношения к x64 в гостевой системе не имеет никакого." ?
