Re: [libvirt] [PATCHv4 4/5] S390: Add hotplug support for s390 virtio devices

From: "J.B. Joret" <jb(a)linux.vnet.ibm.com&gt; We didn't yet expose the virtio device attach and detach functionality for s390 domains as the device hotplug was very limited with the old virtio-s390 bus. With the CCW bus there's full hotplug support for virtio devices in QEMU, so we are adding this to libvirt too. Since the virtio hotplug isn't limited to PCI anymore, we change the function names from xxxPCIyyy to xxxVirtioyyy, where we handle all three virtio bus types. Signed-off-by: J.B.
