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



 But to be clear, the cpu should be left at default x86_64 for the 32bit Windows XP guest.

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.
It shouldn't do that. It should just be using KVM with a 32-bit
CPU model specified. Much older libvirt used to drop back to QEMU
in this case, but we fixed that.
