Title:
libvirt evacute on ppcle failed with IDE controllers are unsupported
for this QEMU binary or machine type
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) liberty series:
In Progress
Bug description:
This is on a liberty release
In evacuate, the image_meta is empty. So, we would get the architecture
information from host.
However, in the nova/virt/libvirt/blockinfo.py
get_disk_bus_for_device_type, we didn't have the bus type default for
ppcle or ppcle64. So, it ended up using IDE for cdrom or disk.
So, the evacuate would failed with
