Hi,

Is the Windows XP 64bit with SP2 supported host operating system? In the user manual is only Windows XP (32bit) but Vista is supported in 64bit also?

Thank's

See section 1.4 of the User Guide.

Yes, I have read that user guide but there is mentioned only 32bit XP supported.

- Windows XP, all service packs (32-bit)

But Vista support is for both 32bit and 64bit operating system.

I need to know if Virtual Box runs well in XP 64 host or do I need Vista for 64bit windows host?

IIRC that was 1.6.6 which didn't support 64bit guests. I am not sure that it is properly supported. Try it.

64 bit Guest support is since 2.0.0.

Yes, we know but the dialogue was about whether XP-64bit is a supported host for 64bit guests. You could definitely install 1.6.6 on XP-64bit, but the issue is that since 2.1.0 (IIRC) section 1.4 explicitly states that "Windows XP, all service packs (32-bit)" is supported contrasted to "Windows Vista (32-bit and 64-bit1)". There must be a reason why XP-64bit is clearly excluded.

Ah, that. Probably because XP x64 wasn't as popular as Vista x64 is. IIRC, driver support was terrible and most users didn't need more than 2 GB of RAM. And even if they did, they either put 3 GB in there computer, or accepted that they didn't get the full 4 GB (though it was possible to see that with /PAE on the boot parameter). Real need wasn't there yet.
