Re: [virt-tools-list] Windows XP 32 guest - i686 or x86_64

Hi,
if I install a 32 bit Windows XP Guest using virt-manager, the default
arch is set to x86_64.
Is there any advantage using x86_64 or should I switch to i686?.
Or does it make no difference.

Hi Grant,

If you switch the vm to 32-bit mode, it will use the qemu emulator without hardware acceleration.

So, you're best off leaving the virtual machine operating in 64-bit
mode, even if the guest itself is running 32 bit software.

Hope that helps. :)

Regards and best wishes,
