[CentOS-virt] Running i386 guests under CentOS7 amd64 kvm host

Hi all,

 Maybe it is a stupid question, but I a totally lost. When I try to configure an ubuntu i386 guest under CentOS7 amd64 kvm host (fully patched) using virt-manager, I can't select what architecture I want to use. If I try to change guest.xml using "virsh edit", I can do it, but guest doesn't starts ...

 Is it not possible to run i386 guests under CentOS7 amd64 kvm hosts??

Thanks.
