Error code 0xc000000e is
STATUS_NO_SUCH_DEVICE, which is a bit sad.
\system32\winload.exe is the first file loaded off the disk (it runs the preboot environement before
\system\ntoskrnl.exe is loaded which is the first bit that anyone would recognise as Windows), so this looks like something in the filesystem driver is objecting to how your virtual machine is representing your virtual disk to the OS (i.e Windows doesn't like the virtual hard disk controller).
Has Windows 8 ever successfully booted up on that Virtual machine before? If not - it may be that the particular virtual machine software you are using isn't supported by the Windows 8 Preview, in which case your best bet is to go and use a different VM software.
If you have booted up on that VM before, this looks like something has gone badly wrong and you might need to reinstall the OS.
