Hello!
I was a bit confused about the patches that landed; I see now that they only
add a PCI controller for modern -M virt, but don't change the virtio defaults
to use it.
Yes, because in first versions i changed the default and was criticized for
it, because it broke
backwards

a PCIe slot (physically it doesn't work)
But how do you know whether the device is PCI or PCIe ? I don't see anything

Hello!
ACKed all the patches, squashed in the 2/4 amendment and pushed. Sorry
for the delay.
Thank you very much.
By the way, just curious, why is there a restriction to plug in most of
devices
Yeah, that's a good question. In a real world, PCIe is perfectly hot
pluggable. Maybe the limitation comes from qemu?
OTOH, why do we require devices to be hotpluggable ?

Virt machine in qemu since v2.3.0 has PCI generic host controller, and
can use PCI devices. This provides performance improvement as well as
vhost-net with irqfd support for virtio-net. However libvirt currently
does not allow ARM virt machine to have PCI devices. This patchset adds
