Hi Daniel,
I want to manage a 32 bit i686 guest on an x86_64 host with kvm and libvirt. KVM is perfectly capable of doing this (look e.g. at http://kvm.qumranet.com/kvmwiki/Guest_Support_Status) but libvirt did not allow it.
So I created the attached patch to allow it and make it easy to extend the capabilities of kvm and kqemu later on.
This is incorrect. KVM is *not* exposing a i686 architecture CPU. It is exposing an x86_64 virtualized CPU which is capable of running x86_64 or i686 guests. No change is required.
Thanks for looking at my patch. I understand that KVM does not offer a i686 host cpu but allows x86_64 and i686 guests.
The reason for my patch was that I could not create i686 guests on a x86_64 host with KVM, the only option offered was using qemu.
Yes you can - just select the x86_64 option. It is refering to the *CPU* architecture that is virtualized, *not* the OS architecture. You can select x86_64 CPU and then install a i386 operating system just fine.
