qemu 2.3.0 added support for enabling armv7l VMs to run on aarch64 hosts with KVM. First patch handles the special command line bit, last two patches are about advertising things in virsh capabilities.
After these patches, 'virt-install --arch armv7l ...' on an aarch64 host with new enough qemu will automatically use KVM and generate a working config.

Perhaps lost by having the tweak dir perms handling patch sneak in... Seems reasonable to me (ACK)... Should there be some way to document how this would be added/usable in the passthrough description in formatdomain? Or somewhere else? Not sure how anyone would know the magic incantation to define/use this... Even though this was posted before freeze, not 100% clear whether it's push-able for this release cycle. John
