[Openstack] [Cinder] Attach the volume in Local Disk failed. The log in nova/compute.log said "libvirtError: unsupported configuration: disk bus 'ide' cannot be hotplugged"

Hi,all The openstack was running on one server in my experiment. The VolumeGroup named 'cinder-volumes' was comprised by a local disk partition whose name was '/dev/sda2'. A volume was created in the dashboard, and I tried to attach it to a running instance. However, the operation was failed.

[Openstack] [multipath] Could I use the multipath software provided by the SAN vendors instead of dm-multipath in openstack?
