[libvirt-users] virtio hotplug in CentOS 5.10 guest incomplete

Hi, I just tried to hot-plug a virtio disk to a CentOS 5.10 guest that runs on a CentOS 6.5 host. The Problem is that while the device shows up under /sys/ the corresponding device node does not: /sys/devices/virtio-pci/virtio0: bus device driver modalias net:eth0 power status subsystem uevent vendor /sys/devices/virtio-pci/virtio1: block:vda bus device driver modalias power serial status subsystem uevent vendor /sys/devices/virtio-pci/virtio2: bus device driver modalias power status subsystem uevent vendor So virtio0 is eth0 and virt1 is vda but virtio2 has no device associated with it. Any ideas why the system doesn't pick up the device all the way? Regards, Dennis
