Re: [libvirt] [PATCH v2 2/2] Allow PCI virtio on ARM "virt" machine
Hi!
Clearly (b). For the default it is important that it is backward
compatible (to older libvirt versions) and works with as many guests as
possible.
One very last counter-argument...
Actually, even if we change our default, we are still backwards-compatible, because older
libvirt automatically adds <address type='virtio-mmio'/> to the XML. So, all
XMLs, created before the upgrade, will have it, so everything will keep working. The only
thing affected by the change is domains created after the upgrade. You'll need to
specify <address type='virtio-mmio'/> explicitly in order to work with older
OSes.
