Cause: Disk hot-plug was blocked for clusters with PPC CPU architecture (for disks attached with VirtIO interface). Consequence: Disk hot-plug feature was disabled in PPC for disks attached with VirtIO interface. Fix: Adding VirtIO as applicable disk hot-plug interface for 'ppc64' in osinfo-defaults.properties configuration file. Result: Disks attached with VirtIO interface can be hot-plugged in PPC clusters.
