Re: [libvirt] [PATCH v5 0/4] qemu: Allow PCI virtio on ARM "virt" machine

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 only into PCI, not PCIe? On machines with PCIe host this seems to do nothing good, only prevents them from using MSI-X. For example virtio-scsi still suffers from this problem. I ignore it for now because we currently don't have vhost-scsi support in qemu. Comments say that "PCIe is not hotpluggable". But why? And why do we mandate hotplug?
