This commit adds hotplug support for PCI devices on S390 guests. There's no need to implement hot unplug for zPCI as QEMU implements an unplug callback which will unplug both PCI and zPCI device in a cascaded way. Currently, the following PCI devices are supported: virtio-blk-pci virtio-net-pci virtio-rng-pci virtio-input-host-pci virtio-keyboard-pci virtio-mouse-pci virtio-tablet-pci vfio-pci Shmem device SCSIVhost device
Hm, how did you arrive at this list? Is it 'anything that uses msi-x'?
I guess it's just any device that libvirt actually supports hotplug for, with a few exceptions (cf. patch 3 and 6). Not familiar wuth msi-x.
